Welcome to my personal blog!

I am doing software development in many areas, with my main fields of experience being cross-platform software (C++/Qt), Android apps (native), Linux & DevOps (Bash/Python/Ruby, Docker, ...).

Open Source is one of my passions -- I am a developer and maintainer of many open projects and regularly start contributing to additional ones. Support me on my mission! My other favourite activities include photography and being outdoor as much as possible. I am too volunteering at the local fire department. I went to school at HTL Braunau (Electronics / Software Engineering & Mobile Computing), studied at FH Hagenberg (Mobile Computing) and work currently at Felgo.

Currently I am mostly developing things with C++, Java, or Bash. As my main desktop OS is based on Linux I always try to build things crossplatform. On the mobile side my main focus is on Android. I am also working a lot on servers and development services, here I use serveral languages/frameworks mostly combined with Bash scripts.
