Experienced Software Engineer/Architect. Expert in Large Scale, High Performance Systems and Realtime 3D as in Social Media and Internet Technologies.

My main technical expertise lies in large scale, high performance software development and architecture, which I gained by working on projects in the areas of automotive, science, military, 3D and games.

In nearly all projects, I worked on the design of the basics, the "engine" and the libraries that make the rest of the project go. I am also known as the go-to guy for those impossible problems that have been floating around unsolved for too long.

Over the 15 years of my professional career (20 years including programming as teenager) I have worked with the following static typed languages: Google Go, C/C++, C#, Java and Pascal/Delphi. The dynamic typed languages I used are: Python, PHP, JavaScript and ActionScript.

I have worked on optimizing performance and memory usage of whole applications and specialized math libraries. This includes using x86 Assembler code (starting with drivers for graphics cards under MS-DOS, games, 2D and 3D rendering as well as wearable military prototype hardware).

In addition to large scale software, I have also developed smaller scale web applications with Java, PHP and Python. Databases I have used include Oracle, MySQL, PostgreSQL and SQLite.

Beside my obvious passion for engineering, I am very interested in economics, finances, work processes and success psychology. In general I want to understand what's going on behind the curtain to see the bigger picture.
