whoami

Hey!! I'm Alexiy, a 3rd year at Purdue pursuing a Master's in CS while completing my Bachelor's as a double major in CS and Math at Purdue with an unbreakable caffeine addiction (even full-timers at SpaceX were concerned...).

I love learning anything new and learn best by getting my hands dirty. For me, the best feeling in the world is when something works/clicks after bashing my head against a problem for hours or even days.

In my free time, I love hiking / mountain biking, and finding excuses to visit coffee shops.
