Firmware & Embedded Systems
Bare-metal and RTOS firmware on ARM, RISC-V, and Espressif — from board bring-up to OTA.
What it is
Firmware that has to run for years in the field, not just demo on the bench. We write drivers, integrate wireless stacks, and stand up bootloaders with secure update paths so the device on the shelf can be fixed in the field.
Board bring-up is part of the practice — first prototype to functional firmware in days, with the hardware/firmware integration debugging that prototype phase always actually needs.

Often paired with
Hardware Engineering
Board-level design for systems where signal integrity, power, and thermals are non-negotiable.
PCB Design & Layout
Two to seventy-six layers, including HDI, flex, rigid-flex, and high-speed — with SI/PI built into the routing, not bolted on at the end.
Manufacturing & Assembly
Prototype to production, SMT and through-hole, with sourcing and quality systems in the same engagement.
