Experience
- BayardSenior React Native and AI IntegratorPUBLISHINGMay 2026 - Today (3 months)Paris, FranceI support Bayard's Digital Factory on the La Croix mobile application (iOS and Android), used by several hundred thousand subscribers.What I bring concretely:
- I take over and stabilize a mature and hybrid React Native codebase (PowerSync, REST API), tackling technical debt on state management (Redux, Zustand).
- I optimize performance where it matters: Android cold start, list rendering, and migration to the New Architecture (Hermes, FlashList).
- I upskill junior developers on advanced React Native patterns.
- I structure the use of AI in the team (Copilot, Claude Code): training on ethical best practices, context management, and agentic AI, with a clear objective of productivity gains.
In the end: a faster and more stable app, and a team autonomous in React Native best practices.📊 Live iOS & Android App · Improved cold start · Team upskilled on RN best practices - The Citadel - ÉPOPÉE
