For the multimedia OS BeOS/ZetaOS I created a audio editor with support for VST plugins. This software is now part of the Haiku OS in a slightly changed version under the name BeAE.

It featured:

- C/C++ code
- VST plugin support. I also worked on the VSTGUI port for BeOS.
- Sample precise audio editing
- Build in effects like loudness, reverb, trimming, normalize, ...
- Virtual memory management to edit files larger than RAM
- Multi-language support

$For my own company, Xentronix, I created the photo retouching software Refraction. It was initially developed for the BeOS platform, and later on for the ZetaOS. The unique part is that every thing in the software is build as a plugin, and it uses drag and drop a lot. It's a fully functional, full featured and quite capable photo/image editor. Besides the development of the framework of the app, I also created all the tools, filters and effects and layer effects. Used skills: - C/C++ - Assembly to speed up core processing - Scripting engine - Multithreading - Multi-lingual - Low-level graphical development - Color spaces, conversions and blending - Image processing kernels - GUI design More info on Refraction: www.xentronix.com$

For Byelex Multimedia, I created an iPad/iPhone application to interact with their Buzztalk platform. The idea was to create a 3D Game-style front-end to their platform using REST to communicate with the backend.

The Buzztalk platform is a very advanced technologic system that can analyze texts and can both tell what a document is about and what the sentiment of the text is. It's capable of creating top lists of the most trending topics on the internet and tell if people talk positively or negative about it, and it does this on a scale.

Using this platform, our client presented us with sentiment lists of names of the most popular names and brands in various categories. The app acts as a search engine and presents these names as images on an 'advertisement' board which can be rotated by swiping to move up and down in the list.

Using our own OpenGL game engine. Written in C++ and Objective C using multi-threading to search and download images through the Bing search engine.
