About

I like working close to the app, where small details change how the whole thing feels.

Most of my recent work has been mobile: Android, iOS, app navigation, authentication, QR and camera behavior, BLE-connected features, and performance issues that show up on real devices.

I also build full-stack web apps, especially with React, TypeScript, FastAPI, Node.js, and SQL-backed APIs.

Experience

2 years of software development experience across mobile and web work.
