I’m a senior full-stack engineer who builds and modernizes high-volume platforms, especially for mission-critical domains like fintech, transaction processing, derivatives/exchange workflows, and enterprise healthcare and commerce systems. I focus on designing reliable microservices, creating secure and predictable REST APIs, and delivering responsive user experiences with React and Next.js—while keeping performance and reliability at the center of every release. Over the years, I’ve led backend-first delivery across independently deployable services, optimized API latency and throughput, and automated workflow reviews to reduce manual effort without sacrificing auditability. I also work end-to-end with CI/CD, observability (metrics, logging, tracing), containerization on AWS with Docker and Kubernetes, and strong testing practices—so teams can deploy faster, troubleshoot quicker, and operate with confidence.…I’m a senior full-stack engineer who builds and modernizes high-volume platforms, especially for mission-critical domains like fintech, transaction processing, derivatives/exchange workflows, and enterprise healthcare and commerce systems.
