About me

I'm a senior software developer in Austria and have been building software professionally since 2011 — mostly .NET and C# on the back end, Angular on the front end and Azure underneath. Right now I work on tax filing solutions, energy forecasting and AI tooling at Guid.New.

It started when I was 14, with Visual Basic 6 and game cheats. War Rock, a free-to-play shooter, was overrun by cheaters who kept wiping the floor with me, so I set out to give a little of it back — Robin Hood, at least in my head. Reverse engineering has stuck with me ever since, though these days purely for fun.

I prefer pragmatic solutions to clever ones, and an abstraction only where it pays for itself. Outside of work I look after spotify-dart, a Spotify API library for Dart, and this blog, where I write up the problems that took longer than they should have.

At home, my wonderful wife, our little daughter and two tomcats keep me busy.
