Sébastien Dominguez — Embedded Systems & Hardware Engineer

01 · Profile

I work across the whole device.

That usually means the PCB, the low-power firmware in C, the wireless and antenna side, the enclosure, and often the interface on top. I started out in industrial design and graphics, so I care about how a product feels and looks, not just the electronics inside. I recently trained as a solar PV installer (Spain, FP Level 2), which keeps me close to hands-on electrical work.
