01 — About

Focused on the details
that users actually feel.

I'm a Flutter developer with a background in mobile product work. I care about animation timing, cold-start performance, and building state management that doesn't collapse under real-world features.

Day to day I work with Flutter and Dart across the full mobile stack — from designing the architecture and integrating REST/GraphQL APIs, to publishing on the App Store and Google Play.
