// manifesto
I build mobile.I build back.I ship everything.
One engineer instead of a handoff chain: app, API, database, payments, store release and analytics — in a single pair of hands. Nothing gets lost between mobile and backend, because it is the same person on both sides.

What I work with
// languages & tools01
Mobile
Flutter apps for iOS, Android, Windows and macOS from one codebase. Offline-first, RTL-ready, released to the stores without drama.
02
Backend
APIs, data pipelines, auth and payments. From Firestore rules to a Postgres schema — no "not my area".
03
Web
Storefronts, dashboards and admin panels that share the same backend as the app.
