    “Prior to bidding cristianocasm said he was available immediately and for 45 hours per week. Then after I accepted his bid he asked for a 3 day extension for what was really a very simple RoR project. I granted the extension. Then by the time of the due date no code had been submitted, not even in draft. Despite the availability of more senior coders he did not ask for help and unilaterally advised that he was giving up. Very disappointing and unprofessional.”

    “Cristiano is really effective. I had him program a statistical algorithm in ruby for risk mitigation models and it wasn't easy because I needed to try and make many changes. He did a good job even to the point of earning a bonus of 50% of the initial starting bid. I will hire him again to make additional changes for this project!”
