Project for Lawrence L. -- 20/12/14 17:59:11

Lawrence's PCB designing and communication skills were top-notch. I asked for additional milestones and he was very accommodating, spent extra time on it, and always gone beyond the tasks needed to help us improve our original designs, and the deadlines were always kept. I´m very happy with the result and I will work with him again in the future.
