Zuma Design is owned and operated by freelance software developer & long time Opencart project contributor Billy Noah and based in Michigan, USA. I specialize in database management, back end development of administrative tools and API integration with payment gateways, shipping carriers and supplier inventory feeds. I can generally be reached 9am - 5pm (EST) by phone, email, or through my website zuma-design.com. You can also find me on the Opencart support forums or over on stackoverflow (http://stackoverflow.com/users/1767412/billynoah).
