Hire senior Ruby on Rails developers

I didn’t start out planning to be a developer—but solving problems though applied technology pulled me in. What began with scripting solutions for tedious workflows turned into building full-scale platforms used by thousands. Today, I’m a full-stack developer and technical founder with a deep understanding of both code and the business logic behind it. I have worked across both public and private sectors, and in industries ranging from Logistics and Aviation, to Retail and Education. My early career experience as a solutions architect reinforced my customer and user concentric approach. What sets me apart isn’t just the code I write—it's my ability to understand what users actually need and deliver scalable, elegant solutions that exceed expectations.

I’m a veteran Ruby on Rails developer with 10+ years building Rails apps—ranging from greenfield to legacy rescue. I help small teams move faster, clean up codebases, and ship features with confidence. Fluent in Hotwire (Turbo + Stimulus), RESTful APIs, PostgreSQL, and scalable architecture. Also experienced in mentoring devs, improving performance, and navigating compliance (HIPAA, PCI, ISO27001). Currently open for ~10 hrs/week of contract work—hands-on coding, tech guidance, or both.

I'm a software engineer graduate who started with curiosity and a desire to create things that make life easier for others. Over the years, that evolved into a deep expertise in building robust, scalable web applications with Ruby on Rails. What sets me apart is not just my technical skill set, but the way I approach problems, with empathy for the end user and a relentless focus on clarity, performance, and maintainability. I enjoy working closely with designers, product owners, and even customers to ensure we’re solving the right problems, not just writing code. I’m especially passionate about developer experience, writing maintainable code, automating workflows, and sharing patterns that make entire teams more productive. If you need someone who can step in, understand a complex codebase, identify what’s slowing your product down, and ship clean, tested solutions fast, I’m that developer.

I’m a senior full-stack developer with over 8 years of experience, primarily focused on Ruby on Rails, PostgreSQL, Sidekiq, and React. I’ve spent the last 5+ years working remotely with US and Canadian companies, building reliable, scalable systems and shipping features that matter. I've worked with teams at GitHub, Sana Benefits, and Lillo — contributing to everything from critical billing systems to product onboarding flows and internal tools. My journey started with curiosity — I loved solving problems and automating anything repetitive. That turned into a career built around clean code, collaboration, and fast iteration. I’m passionate about building real-world products that users love and helping teams move faster without sacrificing quality. What makes me stand out is my ability to go deep into backend architecture while also being comfortable jumping into the frontend or DevOps when needed. I know how to work independently, communicate clearly in async teams, and push work forward without blockers. I care about writing maintainable code, mentoring other engineers, and staying up to date with the tools that make software better — and I’m always looking for product-driven teams where I can bring real value from day one.

With 5+ years of Rails experience, I come with a wide range of experiences and love to delve into new projects. I am working on a variety of pure Rails apps, leveraging the power of Hotwire and TailwindCSS on the front end. My personal project is https://anecdot.co, a platform for recording, preserving, and sharing life stories.

I love to learn fundamentals and solve problems.

A passionate Ruby on Rails developer, author of i Love Ruby https://i-love-ruby.gitlab.io/ I am a person who can build projects on a turn key basis. I completely agree with 37Signals philosophy of developing software. I agree with Rails 100% including the way it enables us to build modern web apps with Hotwire. I am constantly looking for ways to develop applications with perfection and with less of cognitive load for developers. I love to build high performance teams for your business, and keep them mentally healthy so that we have an honest work place where people are free to tell facts.

Hi, I'm Mike! I've spent the last decade working on Rails at scale--from high-traffic APIs to complex backend systems. Beyond Rails, I've built React frontends within Rails applications, shipped React Native apps, and developed native iOS applications. What I bring to teams: * Code quality at scale - I implement systems (RuboCop, ESLint, automated testing) that keep large codebases maintainable as teams grow * Performance-first mindset - I use observability and metrics to identify bottlenecks before they become problems * Deep debugging skills - Whether it's a memory leak in production or a race condition in tests, I'll dig in until we find the root cause Recent technical interests: Hotwire/Turbo, LLMs, agents, and contributing to open source.

I’ve always been fascinated by the intersection of creativity and technology. My coding journey began when I discovered how a few lines of code could transform an idea into a fully functioning application. From that point on, I was hooked: I poured countless hours into experimenting with everything from Ruby on Rails to more modern JavaScript frameworks. Over the years, I’ve refined my skills and found my passion in building clean, maintainable systems that put user experience first. One of my proudest earliest accomplishments involved leading a small team to develop a custom internal tool that automated a tedious data-entry process. Seeing the hours of manual work drop to just a few minutes was incredibly rewarding—it reminded me why I love being a developer in the first place. I’m constantly seeking new ways to grow: whether that’s diving into emerging technologies, improving my testing strategies, or exploring new coding paradigms, I believe there’s always more to learn. Above all, I thrive on solving tricky problems in ways that others might not have considered. I love collaborating with designers, project managers, and fellow developers to turn concepts into polished products. I bring a unique blend of empathy, curiosity, leadership and technical expertise that helps me bridge communication gaps and ensure every project is set up for success. Helping teams build something truly meaningful is what drives me—and I’m excited for what comes next.

I'm Patrick, a backend developer with over 17 years of hands-on experience building web apps with Ruby on Rails—across startups, NGOs, and large enterprises alike. From launching social platforms in Thailand to building insurance portals in Germany, I've worn many hats: freelancer, CTO, and senior engineer. What drives me is crafting robust, maintainable systems that solve real-world problems. I’ve worked on e-commerce shops, benefit platforms, mobile apps, and even refugee registration systems in South Sudan—always with a focus on clean architecture, fast iterations, and reliable delivery. I thrive in complex environments where others might hesitate: legacy codebases, scaling systems, domain-driven design, or integrating with obscure APIs. If your team needs someone to bring order to the chaos—or just ship that one gnarly feature no one wants to touch—I’m your guy. I'm currently based in Hamburg, but remote-friendly and happy to plug into teams anywhere Rails is loved.
