J Delaney, a rising senior at UC San Diego, is an intern on the JSTestFuzz team, a fuzz tester that uses existing tests to create novel ones testing edge cases. He chose to return to MongoDB for his second internship due to the company's great people and real projects. His job involves finding out what caused bugs found by the project, which can be challenging given the amount of code involved. The best part of working at MongoDB is the free food, with a favorite order being a Chop't salad. In his free time, Delaney enjoys playing ping pong and reading, and has secret talents such as knowing sign language. He values his custom keyboard bindings and binge-watches Battlestar Galactica in his downtime. An average day for him involves checking tests, working with the team, and taking breaks to read or play ping pong until 6:30pm.
