Hi, I'm Jan Cernik

I started with Arduino and small electronics projects as a kid, gradually moving from basic circuits and microcontroller code to applications that live in the browser and on servers. That path eventually led me to working on full web stacks and infrastructure, until software became the main thing I work on.

Today I focus on web development and running my own services on Linux, Proxmox and Docker, while still using electronics for personal projects, especially for home automation.That includes custom switches and sensors, self-hosted services and a few experiments that connect the physical side of my setup with the software I write.
