Back to original languageAbout Jérémy
Freelance mobile developer, 7 years of Flutter / Dart experience, including the early years on beta. I support startups and large companies throughout the entire lifecycle of an iOS & Android mobile app: technical scoping, architecture (Clean Architecture, Bloc, DI), development, Firebase integration (Auth, Firestore, FCM, Remote Config, Analytics) and CI/CD industrialization (Bitrise, GitLab CI, Fastlane, Firebase App Distribution).
My recent involvements: technical lead for the multi-brand Renault / Dacia / Alpine mobile app (architecture, remote internationalization, CI/CD, quality), Flutter development of a medical solution for early detection of rare diseases at Zanalys (real-time WebSockets chat, biometrics, Dynamic Links), and architecture design of a white-label app for ticket and payment control for SNCF Connect (unit/widget/golden tests, AWS Lambda, Cognito).
Available for fixed-price or time-and-materials missions, fully remote or hybrid in Lyon.
