Embedded Firmware Teams Can Maintain

Academic and startup firmware often works — until the original author graduates or pivots. Maintainability is a first-class deliverable.

We favor thin hardware abstraction, explicit state machines over sprawling loop() logic, and naming that mirrors the mechanical system being controlled.

Versioned pin maps, calibration notes, and a short runbook turn a prototype into something another engineer can extend without reverse-engineering the PCB.

Whether the target is Arduino, ESP32, or STM32, the discipline is the same: make the next change cheap and safe.
