I'm a full stack developer with 12 years of experience in PHP and 6+ years of specializing in Laravel. I've built and maintained large web applications, internal tools, and SaaS platforms for startups and large companies. I enjoy working on clean, readable codebases and simplifying dev workflows. I'm searching for contract or part-time remote work with a small to medium-sized team that values craftsmanship and clarity. I'm eager to jump into established codebases or help architect new ones.

I’m a web developer with 12+ years of experience helping companies turn ideas into real products. For the past five years, I’ve worked remotely; before that, I was onsite in SF and Berlin, contributing to fast-growing companies (one acquired for $7.1B).

I focus on front-end, UX, and product development, but I’m also comfortable working with back-end code when needed. I’ve led front-end teams and built several products from scratch—always aiming for a great user experience.

Ready to jump on a call and chat about how I can help out!

Sample projects:

https://movieo.me/ - A movie discovery platform (co-founded and got traction on Product Hunt & Reddit)

https://yourmonthly.app/ - A personal finance tracking app (a helpful side project)

I'm basically a jack-of-all-trades software engineer who's done extensive "founding engineer" work in the context of both VC-backed startups and for smaller contract gigs over a period of about 10 years.

I have strong technical foundations, good product sense, and have gone deep with AI/LLM tech both in the sense of being able to use it effectively, and in exploring the design space for products/tools leveraging it.

Tools I use most frequently these days: Typescript, node, React, pnpm+vite. I've also done extensive work with three.js in the past. I used to write a lot of Java and a bit of Objective C, have dabbled in Rust and Elixir.

I've done a lot of work in developer tools and data visualization of various kinds. Data-rich, non-traditional UIs with highly optimized UX, and rapid prototyping are my forte.

I've been basically on sabbatical for a while now, mostly taking the time to learn and build with AI. At some point in early 2024 I decided: okay, time to take this seriously, and have. After the long break, I'm ready to start something new!

I'm David Colgan, independent Django specialist since 2011. I offer three focused services:

1. Relief Developer ($125/hr, up to 20hrs/week) Need to ship faster without hiring full time? I remotely join your team to offload tickets from your primary devs. I'm low maintenance and experienced working async.

Currently providing this service for a leading Django consultancy.

2. Maintenance Retainer ($1k-5k/month) Have a mission-critical Django app that needs ongoing maintenance? I'll own your app's uptime with ongoing security updates, backups, and on call support it if it breaks. Fixed monthly price dependent on response time and complexity of the project.

For 7 years I successfully maintained a Django app for a financial services company that ran their back office with zero breaches or data loss and minimal downtime.

3. Django Rescue (fixed price, 20% upfront/80% on completion) Have a mission critical Django app no one dares touch? I'll bring it up to the latest LTS, set up proper backups and monitoring, and return it to a stable, maintainable state. I've worked in dozens of Django apps from v1.6.

No obligation: with read-only repository access, I'll provide a fixed price quote with no surprises.

If interested, send me an email with a description of your project and let's talk.

Founders Ben [0] and Rob [1] have been friends since meeting at Venmo in 2013. Ben worked at Stripe for 8 years. Rob worked at Fin (human-in-the-loop AI executive assistant, before LLMs) and was founding engineer at Substack. We started our first product, Substrate in 2023, a platform for building agentic workflows, and raised an $8M seed round led by Lightspeed [2]. We were pushing the envelope on both infra (serving multi-model workloads efficiently) and developer experience (ahead of our time in several ways) [3]. Though we found solid traction with startups, we realized inference was a red ocean especially upmarket, and decided to spin down the product/team at the end of 2024. We've spent the last 6 months prototyping and discarding ideas, and we’re now gearing up to launch our latest vision, a consumer AI application.

I'm a jack of all trades. I've built highly scalable telephony systems, industrialised startups, discovered major bugs in Twilio's call routing algos through a handy home-made hardware latency tester, built big data teams and pipelines for pharma companies. I even built an industrial camera for the wine industry in the middle of the pandemic. These days I mostly focus on backend software development and architecture, data-archeology and -science, and trying to build cool stuff.

If you need someone who has the ability to absorb a massive context quickly, and is able to maintain the goals of all the stakeholders in his head while coming up with a solution, I'm your person.

Team engagement, mentoring, hiring, devrel, content creation are all additional skills to programming. Building fast, robust, websites and applications is my bread and butter.

Hi HN! I'm a full-stack developer with a strong frontend focus - 10+ years of experience building fast, clean, and scalable web apps.

On the frontend, I work with React, Vue, and Svelte. On the backend, I've shipped systems using Go, Python, and Node (Nest.js, Django, FastAPI, etc). I enjoy working on thoughtful product design and efficient APIs just as much as hacking on UI.

Lately I've been freelancing through ainurhq.cloud, doing both client projects and internal tools. Some recent work includes:

- jsDelivr: contributed engineering support and improvements

- Radiabase: contributed to a CRM-style lead and sales management platform

- UniDeck: a no-code, plug-and-play dashboard builder with built-in integrations. Built from the ground up with my team at AinurHQ

I'm currently looking for freelance/contract roles (or possibly full-time) - ideally on a modern product team where I can contribute across the stack.

I started programming from an embedded system(little NN/ML applications). Then, I worked on low-level programming a little. I have gone through generic web developments quite often with all major cloud platforms. I'm recently working on game development(as well as the facilities and the devopsy part, so you hear about running registry and tuning docker images more if you talk with me this month). I'm familiar with the most thinkable toolings along with them. For job-seeking, I wish to continue growing in any prospective direction, but with better resources, ideally part-time.

My latest projects have been in full-stack edge ML R&D, memory controller firmware dev for POWER servers, and chip bringup/testing for Z mainframes.

I'm passionate about modular synthesis and tinkering with all sorts of analog circuits and DSP. Currently upskilling in analog PCB design and refining my abilities in FPGA development. Also WIP on a 3D-printed robot arm to practice control systems and actuation.

Hi HN! I'm Erfan Besharat, a Software & DevOps Engineer with 9+ years of experience across backend, infrastructure, and distributed systems.

I specialize in cloud-native architectures, having led infrastructure at companies in the blockchain, video streaming, and ticketing industries. Most recently, I was Senior DevOps Engineer at GET Protocol, where I helped scale a platform serving over 6.5M attendees and $110M+ in ticket sales.

Currently, I'm running my own consultancy/research lab, Ainur Tech (https://ainurhq.cloud) based in the Netherlands. We've been fortunate to support companies and public sector organizations across Europe, from municipalities to small and large software and art studios. Feel free to take a look at our current and previous clients on the website.

I'm also building a side project called UniDeck (https://unideck.app) with our team, a no-code dashboard and portal builder that lets anyone craft personalized web experiences using widgets, integrations, and AI. Think Grafana meets browser new-tab simplicity.

Looking for: - Remote or hybrid DevOps / Platform Engineering roles (Open to Backend roles if it matches my area of focus and interest) - Contract / consulting gigs around infra automation, Kubernetes, and developer experience - Or collaborations with teams doing interesting work in OSS, infrastructure, or developer tools

Technologies & Skills: Software Engineering, Data Engineering, Data Modelling & Pipeline Design, Python, FastAPI, SQL, AWS, Azure, DuckDB, API design (full list on request)

Experienced Engineer looking for software / data engineering contracts to solve business problems.

I usually work on the entire data chain from data generation up to BI or ML use cases at the end. Main focus is data from your business operations (logs, sensor data, process data, ...).

More than 7 years of experience in various industries (Aviation, Automotive, AdTech, ...) where I have helped my clients successfully tackle their challenges.

I’m a senior developer and infrastructure consultant with 15+ years of experience — available for part-time work (24h/week). I help teams move fast without breaking things, bringing deep infrastructure expertise alongside strong full-stack execution.

What I Do Best:

• Cloud & Infrastructure: AWS (primary), Azure, GCP, Terraform, Kubernetes, Serverless, CI/CD (GitHub Actions, etc.)

• DevOps Workflows: Monitoring, cost reduction, zero-downtime deploys, secure secrets management, staging/preview environments

• Full-Stack Development: Node.js, React, React Native, Next.js, Tailwind, Postgres, MongoDB

• Delivery-First Mindset: Recently helped a client setup up CI/CD, staging, and production environments via Kubernetes and compliant — from scratch to deploy — in just 3 weeks part-time

What I’m Looking For:

Teams with meaningful technical challenges — ideally past the MVP/PoC stage and ready to do things properly. I’m most effective where there’s a need to scale infra, clean up dev workflows, or modernize architecture.

Engagement Style:

• Part-time (24h/week)

• Open to short/middle term high-impact contracts, retainers, or embedded support

• Happy to mentor as part of the engagement

Projects:

• deepstream.io – Real-time messaging infrastructure (co-founder)

• pikku.dev – Open-source framework for building transport-agnostic TypeScript APIs

Let’s Talk:

• GitHub: github.com/yasserf

• LinkedIn: linkedin.com/in/yasserfadl

• Email: yasser.fadl [at] vlandor.com

I am a Lead Infrastructure Engineer with 20+ years of experience.

Whether your team is stuck troubleshooting infra issues, needs extra hands on an infra-heavy project or is just lacking tech leadership on the DevOps topics, contact me and we'll figure it out.

I prefer to work along the existing engineering teams, mentoring or training them while working together on the real tasks. This is a very effective and also a flexible way to learn and as a bonus, some work gets done on the way.

I am located in EU (Estonia) and work remotely with occasional on-site visits.

The usual topics are various AWS services, Elastic Stack, Linux, wide range of troubleshooting, infrastructure as code, logging & monitoring, managing cloud costs, but I find it rewarding to venture into new areas together with the team.

We're Stored – a digital payments startup redefining how merchants sell and get paid. We recently closed an oversubscribed funding round, driven by several new partnership agreements with some of the world's largest payments businesses.

You’ll be joining a small team where your work will have immediate and visible impact. The majority of the backend has been built by one of our founders, and you'll work closely with them to help take it to the next level.

What we’re looking for:

-Strong experience with C# and back end systems.

-Deep understanding of Postgres, performance tuning, batching, and scaling.

-Proficiency in TypeScript, and capable of owning full features end-to-end.

-Comfortable handling front end logic (we use Svelte, but experience with any modern framework like React or Vue is fine). To be clear, you won't need to design/build UIs, but you should be able to work across the stack.

-Experience with Linux and networking, especially profiling/debugging in high-traffic production environments is desirable but not essential

-Fluent in written and verbal English

-Self-disciplined, motivated, and able to manage concurrent tasks

This is a fully remote role, but we’re based out of London, UK and so only considering candidates in GMT/BST ±3 time zones who are willing to work between the hours of 8am - 6pm GMT/BST.

Interview process:

1) Initial video chat where we'll get to know you and ask some technical questions

2) Technical exam

3) Final call with the wider team

I have 14 years of experience in Fin-Tech, Journalism, TV and Media, Health, Science, and more. I've taken countless projects from 0 to 1 and worked for clients like JPMorgan Chase, Santander Bank, Rob Walling, Trello, Peter Diamandis, Syncthing, SimplyCredit and others. I'm experienced in Vue.js, Django, Phoenix framework, Quasar and many others, I've worked with most web tech stacks out there. I pick up new tech easily and like working on complex products. Case studies are on my website: https://gilli.is.

I can provide the following for you:

- Product Design — Whether you need a design from scratch, a redesign, or you're having issues with a small part of your product, I can design it.

- Front-end Development — I can build the design into a pixel perfect product. This is rare among us designers and has proven to be extremely powerful for the result since there is less wasted effort. I've worked with a wide range of frontend and backend technologies and can hit the ground running on new projects. I pick up new tech quickly, which makes it easy for me to adapt to different environments.

- Analysis — Your users, know everything that's wrong with your product but have difficulty communicating it. Often it comes out in anger and frustration. That's where my usability analysis comes in. I'll review your app from an outsider and expert point of view, and give you actionable feedback.

- Free advice — You might not be sure if I am the right fit, and I very well might not be. I can help you figure out the best direction to go for free.

I take my work very seriously and put a lot of work into excellent communication, proper planning, and, last but not least, properly understanding your product so that we can produce great results.

I bring your solutions to life.

An Engineer of many hats, I solve your problems and bring them into the world. I’ve built entire systems from the ground up, delivered physical products in a matter of weeks, and kept Oil Rigs working offshore, built departments filled with the best people to produce top results and make the wonderful dreams reality.

With a background in Electro Mechanical Engineering, I’ve designed products for the consumer, offshore, military markets, so I know what good hardware looks like. I’ve built prototypes for many markets, and architected complex systems from concept to retirement, in a complete cradle to grave manner. I’ve worked closely with software teams to guide development of new features to protect marine vessels from GPS jamming, developed APIs for integration and dug through code by hand to reverse engineer old products that haven’t been touched in decades to determine their operation and how they will be supported and upgraded to turn them into the feature they should be.

As an Engineering Manager, I’ve been the driving force behind teams. I’ve worked with remotely distributed teams across many different disciplines, all working towards the end goal without ego getting in the way. My job has always been simple as the EM, give the team the tools and trust they need to do their absolute best.

Your idea is your baby, it’s precious to you. I’ve worked at startups, small companies and mega corporations and I’ve always maintained a very simple philosophy when it comes to work - “are we doing what the customer needs with the best people we can get?”

I’m your mechanical engineer, engineering manager, product manager, systems engineer, R&D specialist, market analyst and head of technology in one, and I’m ready to make your dream the product it needs to be, hardware or software.

An artist by trade, I worked 6+ years in ateliers, leading design projects with a multitude of materials as well as teaching basics in visual awareness, paiting and drawing. Since 2015, I have shifted my focus to digital art, collaborating with a variety of clients to provide illustration services and graphic consulting.

Well versed in python and javascript, but capable in other languages as well (the majority of this past year has been writing zig, and have deployed Java/Golang/C/Dart recently).

Commonly found using Django but not restricted to that. Lots of experience with modern react/vue as well as Flutter. I've been a remote worker for a decade now, so I had a track record of getting things done without direct supervision. I live in the UK but can and have worked with US entities.

Willing to relocate: yes, to any location in Africa, where I can get the necessary permission to live and work. Occasional travel is possible.

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. Now it's time to move on and so I am in the process to relocate to Africa.

I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.

I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve your problems.

I am open to work for companies anywhere as long as the work can be done fully remote from Africa.

While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.

In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up your team.

I am a backend expert, having built and maintained mission critical, low latency and highly available systems for several companies over the last 10 years, in addition to over 20 total years of software development experience. I learn new things extremely quickly. AWS preferred but not required.

You will like working with me because I:

  * hold your goals as my priorities
  * communicate verbosely yet synthesize well
  * my rates are reasonable in exchange for the value I deliver
  * I guarantee I will get the job done

* built the streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions!

* Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service.

* replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund, vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit.

* built a ~50 node, AWS, Dockerized, Terraform-deployed distributed system to provide realtime, transformed trade data from crypto exchanges to a Kafka pipeline and data lake (fodder for an analytics platform). Met 5000msec SLA across arbitrarily many exchanges and ticker symbols. Blue-green deployment for complete CICD safety. Cloudwatch metrics proved SLA was met and provided general system oversight.

* built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.

Hi. I'm Craig. I'm an experienced Senior Software Engineer, Systems Architect and Microsoft Certified Professional with a passion for software development.

I work primarily, but not exclusively, with Microsoft technologies and the .NET / .NET Core frameworks, leading complex and challenging enterprise software development projects to successfully deliver robust, secure, scalable and efficient software solutions, encompassing over 20 years of experience in the field.

CV: Available Upon Request

Email: [email protected]

I am a seasoned (>13 years experience) full-stack staff-to-principal-level software engineer/consultant specializing in the backend, systems architecture, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling.

In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade

More recently, I've built a no-code automated form-filler and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patent-pending process; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).

I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry.

I have extensive experience working for and running both startups and software consulting shops, with some mid-sized company engineering experience as well; which gives me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant/all internal and customer-facing areas of responsibility.

If any of the above seems like a match for you and your organization or project, don't hesitate to reach out.
