About
Software Developer & App Architect
I am a Toronto-based Software Developer specializing in custom mobile and full-stack web application development. Leveraging React, React Native, TypeScript, and Next.js (App Router), I engineer robust, cross-platform iOS and Android apps alongside performant web ecosystems. My tech stack includes Tailwind CSS, Node.js, Prisma ORM, PostgreSQL, MongoDB, RESTful APIs, and state management (Zustand, Redux). By blending engineering rigor with user-centric UX/UI design, I deliver clean, maintainable, and SEO-optimized software architectures tailored for maximum speed, security, and market visibility.
Alongside contract work, I build and maintain RK DevTools, a free, privacy-first suite of 56+ browser-based developer and design utilities — no logins, no uploads, no tracking. It's the same engineering standard I bring to client projects: fast, accessible, and built to actually be used. I also write about the engineering behind these projects on the blog.
