"Jae led our team in building a successful project for our client. He was always on top of things. He was always prepared for meetings and presentations, and always checked in on the rest of the team to see if they needed any assistance and would lend a hand if any was needed. When there were tasks that nobody else would want to do, Jae would volunteer to do them. I am very pleased to have worked with Jae."
