About

Using complex cloud infrastructure to ship real products.

I build production-ready web applications end-to-end, from UI/UX to cloud infrastructure. Most of my work is TypeScript-first (Next.js/Node), backed by AWS services for deployment, scaling, and automation; allowing the product to ship fast and stay reliable.
