Work History & Feedback

Virtual River Facebook API programming

129 hrs @ $18.00/hr
Earned $2,322
“This was a extremely complicated application to create and because I had little understanding of how programming works, Denis had to come up with many solutions to obstacles on his own. He was an extremely great communicator and was able to create program functionality that I didn't even know existed. We had a very tight deadline (3 months) to develop this app and he put in a lot of overtime and extra hours to get the project completed. In addition he patiently worked through the changes and corrected all 'bugs' in the system. We are very happy with the results of this project and the amazing Virtual River application he built to help us engage a large audience in conserving water and tracking it in an online river. We will continue using his expertise as we build and expand on this application in the future.”
