Hire principal / staff Ruby on Rails developers

I started writing apps at 8 years old in Microsoft Access with my Dad. Then 3d games in BASIC, and finally in college PHP and MySQL web apps. Never looked back. Mid-Level/Senior Software Engineer capable of independently developing and assisting in the design of products loved by customers and associates, with many years of experience with full-stack technologies in a cloud environment, and back end technologies such as Java and C#. Great attention to detail with well-architected systems and enjoyable user interactions. Strong communicator with interpersonal savvy.

Over 10 years of experience going from 0 to scale as an Engineering and Product Leader 6× Founding Engineer of multiple successful companies, including a telehealth unicorn Ruby on Rails enthusiast, building real tangible value since v3

With more than 10 years of experience in Ruby and Ruby on Rails, I have a track record of delivering high-quality solutions that meet both functional and design requirements. Throughout my career, I have collaborated closely with product managers and UI/UX designers to scope, design, and implement complex projects. I have also worked with both back end and front end technologies, including React with TypeScript. In addition, I have some experience with a variety of other programming languages, including Go, Elixir, C++, Haskell, Python, and Java, as well as developing my own toy programming languages and DSLs. As a passionate learner, I am always looking for opportunities to work with like-minded people and build the best software possible. During my PhD, I worked on the open-source project Bohrium, which allows for automatic parallelization of NumPy and Ruby code written in C++. Additionally, my implementation of a CSP framework for Ruby benchmarked better than the Python implementation at the time. I am comfortable working remotely and believe that effective communication is key to successful collaboration. When I am not at my computer, I enjoy geocaching, playing board games, and cooking. Jokingly, I have made stickers for my own jam brand. I am committed to becoming the best version of myself and would welcome the opportunity to bring my skills and enthusiasm to your team.

I’m a senior full-stack developer with over a decade of Ruby on Rails experience, having started with it back in 2012. I was immediately hooked by how quickly I could bring greenfield ideas to life using Rails, and despite experimenting with other stacks—like Go, TypeScript, and even Salesforce—I always find myself returning to Rails for its elegance, productivity, and ecosystem. What makes me unique is a strong focus on code maintainability and developer empathy. I’m deeply influenced by the SOLID principles and aspire to write clear, change-friendly code, taking inspiration from people like Sandi Metz. In recent roles, I’ve often been the person brought in to refactor legacy codebases, introduce design systems, and reduce complexity—turning code that others fear into something a team can iterate on confidently. I’ve worked remotely for companies across the US, Australia, and New Zealand, collaborating across time zones to ship features, reduce tech debt, and keep product momentum strong. I'm passionate about building tools that people enjoy using, and I leverage AI tools to improve my speed and consistency, giving me more bandwidth for creative problem-solving and mentoring.

Senior Full Stack Developer with 10+ years of experience delivering scalable, performant solutions across global enterprise and e-commerce platforms. I've led engineering efforts that directly improved business outcomes—cutting page load time by 96% for NinetyPercent.com, boosting form submission rates by 275% at Owens Corning, and reducing security vulnerabilities by 19.3% through large-scale refactoring. At Owens Corning via Toptal, I introduced a reusable geolocation service adopted by 9 datasets and built a multilingual translation engine that improved LATAM and Canadian outreach. My contributions consistently reduce costs, enhance UX, and modernize legacy systems with measurable results. Skilled in Ruby on Rails, React, Symfony, Postgres, Docker, Redis, and CI/CD pipelines, I thrive in remote, agile environments, leading teams with a balance of technical depth and collaborative mentorship.

Senior Software Developer with 10+ years of experience delivering robust full-stack software solutions.

Proven track record architecting cloud-native applications, optimizing CI/CD pipelines, and orchestrating infrastructure. Deep understanding of testing software and continuous delivery systems. Adept at leading Agile teams and modernizing legacy systems to drive scalability, performance, and speed to market.

Full Stack Software Engineer with over a decade of hands-on experience in full-stack development, specializing in Ruby on Rails. Proficient in managing end-to-end software solutions from backend to frontend and mobile applications, with a strong focus on scalable distributed systems including serverless architectures (AWS Lambda). As a Full Stack and Tech Lead at current small company Brightree, I work on different languages programming and tech stacks.

I’m a senior full-stack Ruby on Rails developer with 8+ years shipping production-grade software — from bootstrapped MVPs to fully-fledged SaaS platforms. I thrive in startup environments where shipping fast, clean code is key, and where product thinking is just as important as engineering chops. Rails is my weapon of choice — API-first apps, Hotwire interactivity, background jobs, payments, and complex business logic? All handled. I build with intention, scalability, and UX in mind. Beyond code, I’ve co-founded multiple products, run lean experiments, managed integrations with payment gateways (M-Pesa, Stripe, Paystack, Circle), and built systems used by thousands in Kenya and beyond. I speak startup.

I’m a full-stack web developer with experience in JavaScript and Ruby. I have 15 years of experience working with projects in different industries, from digital campaigns to HR, e-commerce and SaaS products. In my current role I led the development of many modules of the Applications & Leasing system, with a strong dedication in delivering robust solutions that could be extended to support other use cases. Some of these modules include an application template builder, document template builder, lease renewal score and document signing. This experience helped me to expand my ability to connect the dots by understanding each department’s needs and how data flows through the different actors in the company.

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.
