Senior🎓
Top SchoolSébastien Dawans is a hands-on CTO and embedded systems expert with 14 years of experience helping startups turn IoT ideas into production-ready, ultra-low-power hardware and firmware. He leads hardware strategy and rapid prototyping while squeezing microamps from BLE/WiFi wearables, and he pairs schematic/Altium design with firmware, RF/power profiling, and automated production test engineering. As an active contributor to established open-source IoT projects like Contiki and 6LBR, he has improved networking stacks and low-level platform support, reflecting deep protocol and system-level know-how. He advises and partners with early-stage teams to define pragmatic architectures that favor reuse and fast validation, reserving custom silicon only when it adds clear value. Based in Belgium, he also maintains a Python-based automated test framework that accelerates time-to-manufacture across European and Asian production lines.
