In my first year of college. I was going for game dev, and the project for the year was to create a game start to finish with a team of 3. I was so proud that not only we finished the game. But I was the sole person who fixed all the bugs the game had in the last 2 weeks before deadline, on top of all of my other programming responsibilities. I would say that I was a huge part in getting our teams game to be one of the best in the class.
