Ruby on Rails site needs Front-End Skinning

“Upon seeing the specs for the project, Sergio expressed excitement, asked pointed questions about specific components, and got to work. He delivered quality work. When he was challenged by a particular part of the project, Sergio would respond by diving deeper, working harder, and asking for help when he needed it. I believe our project was more intricate than originally anticipated, and that caused us to miss some deadlines… but I think the responsibility for understanding the scope of the project was shared among us, and I appreciate that Sergio stuck with the project. He is a talented developer and an excellent communicator, and I would hire him again in a heartbeat.”

Google Data Rails app- MySQL to Google Docs Spreadsheet integration

“It was a pleasure to work with Sergio, and hope to work with him again soon. Despite a slightly stronger skill set with Microsoft and dot-net development, Sergio's Ruby on Rails skills allowed him to develop our Google API integration with no hitches. It was also a great first experience with oDesk. Was apprehensive at first as it doesn't have an escrow or arbitration system like Vworker. But the lack of those things make for less overhead and smoother work with trusted vendors.”
