This is a new tier I added. Wow, the description for Expert somehow is quite motivating even when I know I am still mediocre at competitive programming right now. In some local circles, you might be considered an algorithms guru of sorts. 1 + Div. The software project consists of many small computing tasks with inter-dependence among them.
