About Me

Engineering systems
built to last.

I'm a Full Stack & Backend Engineer with 5+ years crafting production-grade applications end-to-end — from API design to Kubernetes deployment to observability and monitoring.

At FedEx Corporation, I architect systems processing 10,000+ shipment transactions daily and 1M+ events per day across logistics workflows. My platform CI/CD templates have been adopted by 8+ engineering teams, cutting pipeline setup time by 50%.

I thrive at the intersection of backend engineering precision and DevOps automation — obsessing over latency, reliability, and deployment consistency. My microservices run at 99.9%+ uptime because I treat observability as a first-class concern.

Educated at Texas A&M University–Kingsville (MS Computer Science) and (Bachelor of Technology). Based in Pittsburgh, PA — open to relocation.
