Selected Work
Products I've built and shipped, from SaaS platforms to internal infrastructure.
I build full-stack SaaS platforms that solve real business problems.
I work mostly in the TypeScript ecosystem (Next.js, React, Node.js, Supabase), taking products from zero to production and caring about performance, clean architecture, and the developer experience along the way.
I keep up with the newer parts of the stack and ship production code with Next.js, React 19, Tailwind, and Biome. I'll pick up a new tool early when it actually earns its place. Right now I'm open to full-stack roles where I own a feature from the API to the UI.

Full-Stack Product Engineering
I build and ship complete SaaS products, from the database schema to the polished UI, using the Next.js App Router, Server Actions, and edge-first deploys.

API Design & Backend Architecture
Engineered scalable REST and GraphQL APIs with Node.js, NestJS, and Hono. Deep experience with Supabase real-time, Row-Level Security, and multi-tenant data isolation.

Performance & DX Optimization
Built performance-first frontends with React Server Components, Turbopack, and code-splitting. Cut build times and improved time-to-interactive through profiling and disciplined tooling.
