I am a senior mobile engineer based in the south of France with more than 13 years of experience in Android and cross-platform development. In 2023 I became a full-time solopreneur, focusing on building products with Kotlin Multiplatform and Compose Multiplatform.

• KMPShip: a production-ready Kotlin Multiplatform boilerplate that helps teams launch Android and iOS apps faster, with subscriptions, notifications, analytics, and clean architecture already integrated.
• Bloomeo: a mobile app built entirely with KMP and CMP (with KMPShip) that demonstrates how cross-platform technology can power polished, real-world products.
• Open-source libraries that improve the KMP ecosystem:
  • Passage → Firebase authentication for KMP
  • Alarmee → local and push notifications for KMP
  • Chartopia → charting with CMP
  • Czan → a design system for CMP

I combine deep Android expertise with cross-platform leadership. My focus is on building scalable architectures, shipping production-ready apps, and improving developer experience through open source. I thrive at the intersection of product and engineering, and I am always exploring how modern tools like KMP can accelerate delivery without compromising quality.
