Hello, I am Rafał

For the last thirteen years I have worked on Active Directory and Entra ID: identity, tiering, privileged access, and the unglamorous work of keeping a large directory safe and boring. That is the day job, and I like it.

Evenings are for microcontrollers. It started with an Arduino, picked up WiFi with an ESP-01, and settled on the ESP32. Some of it ends up as a small screen on a desk, some of it as a lamp you switch on by touching the base, or a doorbell that plays the wrong sound on purpose.

Whatever it is, it usually comes with firmware in C++, a browser flasher so nobody has to install a toolchain to use it, and a case off my own printer. All of it is open source, and the enclosures are on MakerWorld. If you build one, tell me what broke.
