I build scalable Node.js and TypeScript backend services, distributed workflows, and reliable APIs.
IndiaWhat I'm looking for
At Thoughtworks, I build backend services for Kaluza and TeamLease, owning API design through production support. I migrated 200K+ records with near-100% data integrity, improved processing throughput by about 60%, and built a Kafka-driven notification engine handling 10K+ concurrent messages.
I work across Node.js, TypeScript, Fastify, AWS, Kafka, distributed systems, and observability. I also mentor interns, conduct code reviews, and build tested services using unit, integration, and contract testing.
