Bryan Beltrán

Software Engineer II at Chewy — event-driven systems, observability, and developer tooling

About

I work on Chewy's Agent Experience team, building systems for customer care across chat, phone, and email. I was recently admitted to Georgia Tech's Master of Science in Computer Science program and will begin in Spring 2027, following the Machine Learning track. Side projects solve problems in my own life and give me room to learn.
