I build scalable Node.js microservices and high-performance backend platforms.
IndiaWhat I'm looking for
I've built backend systems for Circana's CoinOut loyalty platform, supporting real-time purchase tracking and automated rewards for 100,000+ active members across 26 merchant partners.
I design Node.js, NestJS, Express.js, Fastify, and Koa services across e-commerce, retail, pharmacy, and rewards products. My work has reduced API latency from 800ms to under 200ms through Redis caching, indexing, and API optimization.
I've shipped 10+ production backend systems across AWS, Azure, and GCP, while leading a five-engineer team through delivery, code reviews, and technical mentoring. I focus on reliable microservices, data pipelines, CI/CD automation, and measurable product outcomes.
