I’m a full-stack engineer focused on distributed systems, security-first engineering, and infrastructure that stays fast under pressure. I’ve spent 1.5+ years building production-grade, real-time WebRTC systems and event-driven microservices designed for measurable performance.

At Capsitech IT Services, I engineered REST APIs with JWT auth and RBAC middleware, and enforced OpenAPI/Swagger specs across 10+ services—reducing cross-team integration bugs by 60%. I built WebRTC + Mediasoup SFU messaging and HD video calling with optimized TURN/STUN on EC2 to achieve sub-100ms latency, and I cut admin overhead by 70% through hierarchical RBAC workspace modules.

I also introduced event-driven architecture using RabbitMQ + BullMQ to decouple async workloads and eliminate request timeouts during burst traffic. On the platform side, I improved release velocity using GitHub Actions + Docker (cutting release time from hours to minutes) and strengthened observability with Prometheus (reducing MTTD by 50%), while continuously optimizing data and infrastructure for high-concurrency workloads.
