About Me

My name is Stefan. I came up with STFN way back in 2007 when I was looking for a cool username for DeviantArt, and at that time I though that “stfn” looked good. And it stuck for every platform I have ever used since.

I work as a Python developer, and I am a Python developer after work. I learnt it by myself back in 2019 when I decided I no longer want to be a project manager. I was lucky enough to get a job in IT without previous commercial coding experience, and here I am.

In the past I used to be deep into analogue photography, and into building bicycles. Today, my hobbies include Raspberry Pis, microcontrollers, and any kind of tinkering that connects programming with soldering. I also became interested in ham radio, both in the traditional sense of voice communication, and also in the more modern digital communications such as APRS, FT8, LoRa and Meshtastic.

Apart from IT stuff, and I’m also into gardening, permaculture and off-grid installations. I’m an Avgeek, despite being very concerned about the climate emergency we are in right now.

I’m getting married this year!

Politically I’m a rather radical leftie.
