About
Crafting reliable systems
for critical transactions

I'm a software engineer who thrives at the intersection of complex distributed systems and real-world financial infrastructure. Over 5+ years, I've progressed from building healthcare claims systems to architecting payment processing microservices that handle millions in daily transaction volume.

Currently at Texas Capital Bank, I work on treasury and payment services — integrating ACH, wire transfers, and FedNow instant payments while ensuring every transaction settles exactly once. At PayPal, I built GraphQL-based subscription services powering recurring payments across 200+ global markets.

I care deeply about reliability, data consistency, and building systems that teams can trust in production.
