Description

# Android/Kotlin Specialist (+9 years of experience), I have contributed to apps used by millions of users (Carrefour, Eurosport, GoPro). Scalability, monitoring, and security are at the core of my work. Convinced that a developer must stay up-to-date, I have integrated AI into my daily workflow (agents, custom skills for Claude Code/Copilot) for better velocity without reducing quality.
