招聘 mid-level 自由职业 Ruby on Rails 开发者

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.

I majored in mathematics at Penn State, where I worked on simulation and data modeling projects. I found myself drawn more to the coding side than the math itself, and after graduation I pivoted into software development with the goal of building tools that people actually use and rely on. I now work at Alpha Omega Integration on a USCIS project where we’re digitizing the asylum and refugee process. I’ve led a refactor that made our Rails architecture form-agnostic, which prevented a costly split into multiple systems. I also migrated our test suite to Playwright, cutting runtime by over 75 percent and helping us ship with more confidence. Rails has clicked for me because it encourages clean, readable code and rewards long-term thinking. I care about building systems that are easier to reason about, easier to maintain, and easier for others to step into. Whether through thoughtful refactors, clear conventions, or active collaboration, I try to make code better for everyone who works with it.

I'm a full-stack developer with a strong foundation in React and Ruby on Rails, and a track record of building fast, reliable, and user-focused applications for startups. I've contributed to products across fintech, SaaS, e-commerce, and healthcare—adapting quickly, shipping often, and solving real-world problems with clean, scalable code. I thrive in fast-paced environments where collaboration, curiosity, and impact matter most.

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.
