    Exceptional work. This was a long and involved project. It involved Ruby, Rails, and Javascript. Sophy excelled at all of them. He followed BDD practices and set up a new test data factory system. He researched new technical topics and recommended sound solutions. He understood the requirements well and collaborated with others on the team. He stayed up late at night to get work done. His code was of high quality.
