About Grum

I'm the lead developer of the Crazy-Froggers, the CF12.NET and all of our game modifications. I define the standards, design the architecture of our systems and set the technical directions CF goes. Passions of mine are gaming and the creation of digital goods. I do competitive gaming, game modding and develop various - also online driven - applications. Especially systems that interact with each others have drawn my attention.


Born in the old german hanseatic city of Stralsund 30 years ago, I live and work in Hamburg by now. I'm employed as IT-Consultant and software developer for an IT consulting company and work for a global player of the consumer goods industry. Happily married I am too. As many others, I enjoy to explore foreign nations and cultures. Since history is also one of my hobbies, I have a notable collection of old german and prussian military. Aside of german, I speak english, russian and a few words tagalog.


I program internet-based and desktop applications as well as web applications for different needs. The coding language doesn't matter to me but I usually use PHP for web applications and C# for windows desktop applications. You can find my portfolio of programs and tools here.


As I mentioned already, I like to create digital goods of all kinds and since the most games I appreciate often don't fit my expectations in detail, I try to modify them according to my needs. I'm very familiar with the unreal engine 2.X and general game modding like scripting, mapping, a little 3D modelling, UV mapping and texturing. I do enhanced scripting for Morrowind using the community provided Script Extender and Morrowind Enhanced. Creating simple shaders counts also to my limited repertoire of skills and knowledge.

Since community work and activity often means bitching around with several personal issues and differences with other persons, you won't find me very active in any community but this. I'm simply tired of all the idiots and wannabe heroes out there.
