About

Hey
there.

I'm a Software Engineer at Visa in Austin, TX. I hold a B.Sc. in Computer Science from The University of Texas at Dallas and have been writing code since a sophomore class in 2017.

At Visa, I build software for global payments infrastructure. Before that, I spent two years as a cloud platform engineer — designing automation pipelines, migrating workloads, and making AWS environments cheaper, faster, and safer.

Outside of work: snowboarding and film photography.
