HDR rendering).

Bizarre Creations::Graphics Programmer September 2005 – March 2006 Liverpool, UK

I worked on the company’s proprietary 3D engine and on visual effects specific to The Club. I implemented HDR rendering and many other features in the engine, and was in charge of post-processing effects, such as depth of field, bloom, tone mapping, and colour curve controls.

I have started learning programming at an early age with the dream of one day becoming a game programmer. I wrote my first 3D engine in pure assembly in 1995. I became involved in the Amiga demoscene, and was a member of the groups Frame 18 and Scoopex. I also enjoy playing video games. One of my recent hobbies is photography. This has inspired me to take an interest in the image processing algorithms used to make the most out of digital camera images.
