Your ESP32 project keeps changing: new PCB rev, pins moved, features split into lite and pro, customer settings differ, and now the firmware is a mess of branches. I build ESP32 firmware in C++ (ESP-IDF) so you can generate clean, repeatable builds per hardware revision and product variant from one maintained codebase. You’ll get flashable firmware binaries for each variant, the full source repo, and simple build scripts so you can produce the right firmware on demand. The project is structured to survive real-world changes, with solid logging, watchdog recovery, and clear handoff docs that explain how to add a new variant without breaking everything. I have 12 years of hands-on engineering across robotics, industrial equipment, and embedded systems. I’ve built and supported production control software where reliability matters and failures are expensive. If your requirements are still fuzzy, that’s fine. Message me and we’ll do a quick call to clarify scope and lock the right package
