I build and ship production software, not demos. In about 1.5 years at Teramob Technologies, I've shipped 20+ production mobile apps that have collectively crossed 160,000+ downloads. I also published my own Flutter package on pub.dev and have customized and forked others for use across our apps.

My strongest area is Flutter and mobile development: Clean Architecture, state management (BLoC / Riverpod / GetX), and native platform integration. I'm now extending into backend development with Python, FastAPI and PostgreSQL so I can own features end-to-end, from API to UI.

I use modern AI-assisted development tools to investigate unfamiliar technologies and speed up implementation, but I direct, debug, and validate the resulting code myself rather than accepting it at face value.
