Full-Time Roles

Scrappy ex founder and developer with a can-do attitude.

I am an ex founder of multiple dating/consumer social apps. I now help companies in rapidly developing web and mobile applications without compromising stability. What sets me apart is my ability to tackle challenges with minimal or no guidance, driven by the persistent determination akin to an 8-year-old requesting a Lego set.
