Summary
🤩
Rockstar🎓
Top SchoolDonatien Garnier is a seasoned embedded systems engineer and entrepreneur with 12 years’ experience building IoT and Bluetooth/NFC solutions and currently co-founding Blecon in Cambridge. He progressed through technical leadership roles at Arm—culminating as Principal Software Engineer—where he made substantial contributions to Arm Mbed OS and Zephyr RTOS, including low-level USB and L2CAP work that demonstrates deep hardware-software integration skills. A founder of multiple startups and former CEO of a company licensing NFC & BLE firmware, he blends product-minded leadership with hands-on device driver and interrupt-level development. Educated at Ecole centrale de Paris/CentraleSupélec, he pairs rigorous engineering training with a track record of shipping connectivity toolkits (notably work tied to an award-winning ARM/Vodafone kit). Colleagues describe him as a pragmatic problem-solver who moves between strategy and the silicon edge with equal fluency.
