About

Software Engineer with ~6 years building enterprise-grade distributed systems across fintech and ed-tech. I specialize in scalable backend platforms, cloud-native infrastructure, and cross-border product launches — delivering work that reaches tens of millions of users and spans multiple continents.

I hold an M.S. in Computer Science from Arizona State University and currently work on expanding PayPal's global credit portfolio. Outside of backend systems, I'm actively building into AI/ML engineering, bringing agentic workflows and LLM-powered tooling into daily engineering practice.

Outside work: Formula 1 obsessive, football fan, and .
