What I'm looking for

I seek a senior technical role leading scalable, reliable systems and teams, with strong emphasis on observability, CI/CD, and measurable performance improvements.

I am a senior software engineer with extensive experience designing and delivering large-scale, distributed, event-driven systems for high-traffic products. I have led decomposition of monoliths into microservices, standardized low-latency service communication with gRPC and Kafka, and modernized frontends with micro-frontend architectures to improve performance and deployability.

At Roblox I architected services for Groups, Messaging, Economy and Inventory with sub-200ms p95 latency under bursty load, implemented observability with Datadog and Prometheus, and enhanced CI/CD across Kubernetes on Azure and AWS. Previously, I built a HIPAA-compliant telehealth platform with real-time WebRTC video, secure APIs, HL7/FHIR integrations, and AWS infrastructure automation.

I mentor engineers, drive architectural decisions, and emphasize reliability, security, and scalability through testing, load validation, and automated deployments. I seek roles where I can lead system design, improve operational excellence, and deliver measurable performance and reliability improvements.
