I am a student at Poznan University of Technology. I have a BSc degree in Computer Science and now I am on last year to reach MSc. I have used Qt in most projects since I know about it.
I have done projects in many languages, apart from C++ and Qt there are projects in Python(PySide), Delphi/Pascal, Assembler, Lex/Yacc, VHDL.
I have used Qt also in final project where a tank was controlled by distributed system (cameras, wifi, bluetooth and more). I wrote a port of desktop application to my N900. You could control the tank, view video from different cameras and communicate with other people connected to the system.
Recently I have started a 3D game engine project for N900, beginning from setting everything up: UI, sound, OpenGL ES 2.0 and shaders, settings, input. I think there is a lack of something like that for Maemo and MeeGo, especially the version 2.0 of OpenGL ES should get more attention. Apart from that I want to realize my idea of modular emulator entirely written in Qt. It would be nice to make it all for the new MeeGo phone.
