    I'm a composer and sound engineer with over 15 years experience playing in live bands and producing music for various projects. I have produced over 70 professional songs in 2014 alone. Just take a look at my feedback and you’ll quickly see why I’m one of the top 1% contractors on oDesk. I'm currently the 'go-to' audio guy for several developers who make iOS/Android games. I am one of the most affordable composers you will find. 

I'm also a full time freelancer. That means I'm not doing this on the side so you'll get the quickest turnaround imaginable. Published Games:
