What I'm looking for

I seek a hands-on engineering role focused on performance, reliability, and scalable web platforms with strong CI/CD, observability and team collaboration.

I am a Full Stack Developer who builds scalable web applications using React, Next.js, Node.js, Express and MongoDB, with a strong emphasis on performance, observability and predictable API contracts.

Across roles at Tata Consultancy Services, TechnoMold and university projects, I reduced p95 latencies, stabilized distributed flows with Redis/Kafka/BullMQ, and implemented CI/CD and containerized deployments to improve reliability and delivery speed.

I deliver measurable outcomes — smaller QA and incident rates, faster endpoints, and safer auth and billing flows — by focusing on caching, query optimization, typed APIs, structured logging and resilient integration patterns.
