I participated in a team that designed the Xvive Mike guitar pedal. My main contribution was the audio signal processing code (equalization and level control) and also the code to generate the equalization parameters. I modified an existing hardware design for this specific pedal. Buy the Xvive Mike here

Another project was writing python/Django web site tests as a subcontractor. Although I wasn't under NDA at the time I'm not sure that I should go into more detail. This gave me a chance to improve my python skills and gain more familiarity with HTTP packet data.

I have also been involved in writing mathematical and embedded software, and designing hardware, but under strict NDA.
