Just another coder. (Programming is fun!)
Currently in HFT (high frequency trading) which makes it fun using C++ to push the limits what can be done on an Intel off-the-shelf chip. And I paid to do it!
My area of expertise shifts according to the job I'm working in: Video (MPEG), Embedded (PIC32, MSP's of various flavors), Full-Stack (Linux, PHP, SQL)
