Freelancer profile translated to English.

Description

Flutter & Android Studio based in Nyon (French-speaking Switzerland). I support companies, agencies, and project owners in the creation, finalization, and publication of Android mobile applications on Google Play.

My concrete proof: Station Math, a gamified educational application published in production on Google Play (package com.stationmath.app), complete Flutter architecture with Riverpod, adaptive engine, and progression system. About ten active alpha testers.

What I deliver:

- Native Android applications in Flutter, from design to store

- Google Play AAB publication and signing (alpha, beta, prod, certificates, JSON credentials)

- Migration of existing apps (Capacitor, PWA, web) to native Flutter

- Takeover and finalization of ongoing Flutter apps

- Material 3 UI redesign, animations, Riverpod state management

My method: clean code, defined scope, deliveries tested on a real device (Samsung S23) before announcement. Direct communication in French. No bullshit, no hidden delays.

What I don't do: native iOS, custom backend, PHP/WordPress.

Available for short assignments (bug fixes, AAB signing, publication) and complete projects (MVP, redesign, finalization).
