Welcome to my personal blog with main topics Android, Linux & Open Source!


I am doing software development in many areas, with my main fields of experience being cross-platform software (C++/Qt) and Android apps (native). In development teams I'm usually responsible for managing development services, setting up CI/CD jobs and keeping everything uptodate. For various tasks I love to script with Bash, Python or Ruby. Beside software development I'm also educated in electronics. I'm building small scale home automation, IoT and retro gaming solutions for myself and my friends, preferably with Arduino and Raspberrry Pi.

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) and studied Mobile Computing at FH Hagenberg. I'm now employed at V-Play as software engineer.

Support me

If you like my work or just want to spend me coke beer or coffee, consider a small appreciation via

I’m too active on Battle.Net + Steam and always happy to give (old-) new games a try. If available I prefer to play Open Source or DRM free games, e.g. from Humble Bundle and alikes.

  • If you plan to signup for Humble Monthly you can use this referer link, which gives me free credits if you subscribe.
  • Let me know if you want to get started with some Blizzard game, I will gladly send an invitation (benefits for both).

Development

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. For embedded/IOT development I mostly work with Atmel or ARM based platforms (Arduino, AVR, Raspberry Pi, i.MX, ..).

Here are some more platforms, frameworks, services and technologies I used for development:

  • Java, Android
  • C++, Qt
  • F-Droid, OpenStreetMap, osmdroid
  • Bash, Go, Python
  • MySql, PostgreSQL, Sqlite
  • C, Β΅C(Atmel), Arduino
  • C#, Mono, Unity, Windows Phone 8.1
  • PHP, HTML, CSS, JS, Node.js
  • REST WebServices, Swagger
  • JSP/Servlets, Slim PHP, Flask
  • LaTex, Liquid, Markdown
  • iOS, Swift

  • CircleCI, Jenkins, GitLab CI, Travis CI
  • GitHub, GitLab, Gitea/Gogs, Bitbucket
  • Bugzilla, JIRA, Trac

  • Atom, Eclipse, Vim, Qt Creator, Unity
  • Visual Studio, Mono Develop, X-Code
  • Android Studio, IntelliJ, PyCharm, PhpStorm
