    Train me to use OpenBravo POS.
    Gildardo was amazing. He was absolutely brilliant, on time, and could answer any questions I have. He was able to talk to me on a very technical level, yet explain things so well, that even a "dummy" could understand what he's talking about. He was readily available. Unfortunately, my personal client put the project on hold. As soon as my client restarts the project, I will be hiring Gildardo immediately. Great person to work with and I've worked with a lot of oDesk individuals. He's really one of the best.
