Senior software engineer/architect with 15 years of experience

I have worked on multiple large scale (multi million lines) and perfomance critical projects with C++ and C# but also on smaller web and mobile projects. Realtime 3D graphics has always been one of my favorite topics and I have developed 3D engines for automotive applications, a military geo information system and shipped two games, one on PC another one on PS2, Wii and Xbox360.

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.

One of my strong points is definitively my experience in a broad range of software development areas: 3D and games on PC and consoles, systems architecture, desktop software, server software, mobile app, web and social media, SQL and NoSQL databases, development on Windows, Linux and MacOS X with C/C++, C#, Delphi, Java, JavaScript, ActionScript, Python, PHP, Go, Shading Languages, Assembler.

My latest project is a high level web-framework for Google's new programming language Go: https://github.com/ungerik/go-start
