Denver
Stefan is a software engineer with experience developing code for CenturyLink's bill payment services, leading teams of Red Hat JBoss BPM software consultants, and developing Pega BPM prototypes along with becoming a certified Pega System Architect. Stefan is currently spending time away from software consulting to pursue personal projects that may or may not become startups, to teach, and to practice his programming chops by curating HackerRank's programming challenges. Stefan is a graduate of Centre College where he studied computer science and dabbled in history, theater, and pottery. He'll talk your ear off about coffee mug design, so be wary if you find him holding a coffee mug, which unfortunately is likely at all times.
