Senior🎓
Top SchoolSébastien Vitard is a seasoned iOS and Android developer with over a decade of experience building mobile apps and hybrid frameworks since 2010. After cutting his teeth at Haploid on high-profile media and fintech apps, he co-founded Kristal to continue developing Cobalt, a cross-platform hybrid framework and a suite of customer-facing apps. He balances hands-on native Android/iOS work (Popcarte, Nokia Smart Office) with framework-level engineering, embedded sensor integrations (BLE, NFC, LoRa) and single-app/locked-terminal projects. Based in Lannion, Brittany, he transitioned to freelance in 2020, bringing both product-minded startup experience and long-term client maintenance skills. Notably, his background combines low-level electronics work and mobile sensor data collection with large-scale app delivery, making him effective at bridging hardware, middleware and user-facing mobile features.
