About

I build things for the people

I build production web applications end to end, with a focus on performance, clean architecture, and solving problems beyond what's in the spec — not just implementing tickets.

My strengths are in backend logic and system design: caching strategies, API architecture, and integrating complex systems (payment/financial APIs, third-party platforms, AI APIs) cleanly into a product. I've also taken on legacy modernization work, migrating older systems to modern stacks without disrupting what's already working.

Currently freelancing on Upwork while open to full-time Full Stack / Backend roles.
