What I'm looking for

I’m looking for a role where I can lead backend engineering for secure, low-latency microservices in high-availability environments—building distributed systems with real performance and reliability impact.

I’m a Senior Backend Engineer and Team Lead with 10 years of experience building scalable backend systems across fintech, quantum computing, and defense technology. I focus on secure, low-latency REST/gRPC APIs, microservices architecture, and distributed systems that stay reliable under real production load.

At PayJunction, I led backend engineering for a cloud payment processing platform—driving secure Node.js microservices, improving performance by reducing API response latency by 40%, and raising uptime to 99.9%. Earlier at IonQ, I built backend services for cloud-accessible trapped-ion quantum job scheduling, delivering over 20,000 monthly job executions with 99.8% availability and a 35% reduction in queue time; before that at Shield AI, I delivered low-latency telemetry and mission-critical backend systems that reduced processing latency by 30%.
