Ototek is the tablet of the ARES damage-management ecosystem: every repair type gathered into a single Flutter application, with three mini-apps sharing one codebase — RSS (insurance damage expertise), RSA (workshop management for technicians and chiefs) and ROEA (vehicle inspection). Five languages (TR/EN/DE/AR/CS) with full Arabic RTL support.

Technologies: Flutter, Riverpod/Provider, auto_route, gRPC + REST, Sentry, Firebase Remote Config, OneSignal, Codemagic CI

Since February 2026 I’ve been the senior mobile developer — and because I also wrote the backend of many of these features in ARES V2, I own them end-to-end from API design to the tablet screen. 291 commits, 60 test files.
