Topcoder is a great opportunity for learning and improving your skills, meeting people from all around the world, winning trip to the USA, and all this, while having fun.
The things I'm the most proud of is probably reaching the 3rd place in the marathon ranking, and reaching the final three years in a row.
Besides Topcoder and other programming contests, my hobbies are game design, movies, and video games.
Always assume that you can do (much) better.
I didn't had any programming contest experience before starting on Topcoder, so I didn't have any big expectation for the first marathon match in which I participated.
I didn't qualify, but was close enough to get hooked…
