Tim Dumol is an avid competitor in programming contests, a machine learning enthusiast, and a full-stack developer. He has been in love with math and coding since high school. Tim’s first foray into open source was in his senior year at high school, where he was a heavy contributor to the web UI for the Sage mathematical software package. Thereafter, he discovered the excitement of programming contests, and placed in several national and international contests, such as the Google Code Jam, the Manila Game Jam, and the ACM ICPC. While competing in college, Tim freelanced for a couple of years until he was found by Kalibrr, where he now works as its Chief Software Engineer. This makes him without a doubt, a programmer of such great kalibrr.
