Hey!! I'm Alexiy, an incoming MS student in CSE at UCSD (Graduted from Purdue with a BS in CS and Math May '25!) 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 / skiing, and finding excuses to visit coffee shops.

Feel free to reach out!!
