About

I'm Steven Armenta, a Southern California–based Software Engineer with a Bachelors in Computer Science from SNHU, currently pursuing my Masters in Artificial Intelligence at UT Austin.

This site is my public study journal. I keep notes on the algorithmic problems I work through — not just the solutions, but the patterns, the wrong turns, and the mental shortcuts that make new problems feel familiar.
