Code Review & Repair

Your ESP project won't work? I'll find the bug.

Got an ESP32/ESP8266 project that doesn't work, crashes or behaves strangely? You send me your code + a short description of the problem — I find the bug and deliver a tested, working version back to you, including a brief explanation of what was wrong. Whether Arduino, PlatformIO or ESPHome — send me your code and a description of the problem. Scope: up to approx. 500 lines of code / 1-2 files.

Good to know

Pure software/code analysis: hardware defects, race conditions or bugs that only occur sporadically under load cannot always be reliably found from the code alone.
A service alongside my main job — the stated delivery time is a guideline, not a committed deadline (see Terms for details).
