招聘 senior 自由职业 Ruby on Rails 开发者

My most recent adventure in Rails involved building a real-time visualization feature, powered by Rails 7 and Hotwire technology, for a remarkable number of concurrent consumers. That project proved the productivity and low maintenance burden of applications built with Rails 7, AnyCable, Turbo, Tailwind, and Stimulus. I have experience in all areas of full-stack application development. I have used Terraform to create Kubernetes clusters in the Google Cloud Platform, built data pipelines with Kafka and PostgreSQL, and, of course, created and maintained production Rails-based applications from Rails 2 to 7. I currently build web-based applications with NestJS (Node) and React via Typescript. I am particularly proud at how quickly I am able to adapt to different paradigms and techniques. Take a look at my Github, I also have experience in Elixir and the Phoenix framework. I’m learning Swift; all to say that I’m always eager to improve my craft through any type of project.

I'm a full-stack developer passionate about building scalable, secure web applications that solve real-world problems. With a strong foundation in Python/Django and Ruby on Rails, I've delivered high-impact systems for government, logistics, and healthcare—most recently developing a secure logistics platform for Kenya’s Ministry of Defense. I’ve modernized legacy infrastructures using React, Node.js, and AWS, and contributed to AI research at Scale AI by refining code generated by large language models. I care deeply about clean code, performance, and delivering solutions that drive efficiency and growth. Let’s build something that matters.

Hello, I'm Jonathan. I like solving problems—often with code. I'm a full-stack engineer with 7+ years of experience building scalable web applications, primarily with Ruby on Rails. I thrive in environments where I can own high-visibility projects, collaborate across functions, and move fluidly between strategy and execution. I'm also very comfortable in asynchronous workflows and product-driven teams. I've built integrations with external APIs, including payment processors and Visa, and I've led projects from idea to launch. Mentorship is part of my rhythm—whether through pair programming or thoughtful code reviews. Lately, I’ve been working on a personal project: an AI-powered productivity app designed to help users set goals, track tasks, and build momentum. I care about clean architecture, thoughtful collaboration, and building tools people actually enjoy using.

Hello, I’m a software developer based in Brooklyn, NY. I moved into software after a long career in digital marketing. Ruby was the “new hotness” when I started, and ten years later it’s still one of my top choices. Recently I’ve been diving into pure functional programming with Scala 2 and front-end libraries like Effect. Rails remains my happy place -I love the autonomy and speed it gives small teams. I prefer hands-on IC work, but I’m happy to help plan and organize when needed. Colleagues and managers often describe me as someone who “gets sh*t done” - a badge I wear proudly! I’d love to hear what you’re working on. Feel free to reach out!

I'm a full-stack developer with a strong background in Ruby on Rails, Turbo/Stimulus, a solid grasp of MySQL and even dabble in some Rust. My specialization is building clean, scalable web applications—whether it’s a subscription platform, a CMS, or a custom developer tool. I prioritize practical, maintainable solutions by getting to the root of the problem and applying the right tools to the right job. Over the years, I’ve led the development of multi-language CMS systems, architected data pipelines between third-party APIs and e-commerce platforms, and built gems and libraries to improve internal workflows. I enjoy taking projects from the ground up, designing both backend logic and the frontend experience. I’m a clear communicator who thrives in autonomous environments. I’m fluent in English and Dutch, with working knowledge of Spanish. Outside of work, I’m a trail runner and fermentation enthusiast, always curious and always learning. If you're looking for a developer who delivers high-quality, thoughtful solutions with minimal hand-holding, I’d be happy to connect.
