Embedded developer. Passionate about STM32, Linux and C. Welding steel, building railroad, taking photos, messing with music, playing games, wondering about sewing and many more!

I make living as embedded developer, but lately my work was taking unexpected turn to DevOps and Configuration Management topics. This happened since I dared to ask who will clean up all the mess we have in our repositories. Turns out, I will.

As DevOps I'm working around the clock to pull small department of embedded developers out of dark ages of proprietary build tools. Fighting corporate rules and biroquarcy in progress to bring our department state of the art tools and environment.

Before starting my journey full of yaml files on GitHub enterprise server I was enjoying mostly bare metal development for STM32 and embedded Linux on AM64 platforms.
