What I do

I build full-stack web applications end to end — from database and API design to production-ready front ends and deployment.

Frontend

Clean, responsive interfaces in React and TypeScript, styled with Tailwind CSS and built for accessibility.

Ship & operate

Docker, Nginx, and CI/CD pipelines to get software into production and keep it healthy.
