What I'm looking for

Senior backend engineer with 6+ years of fintech experience building high-volume, low-latency systems (UPI/payment flows, distributed transactions) using Node.js, TypeScript, NestJS, Go, and AWS. Looking for a senior backend or full-stack role, remote or Pune-based, at a fintech or high-growth startup where I can own core architecture.

I've built high-throughput fintech, payment, and distributed systems at InCred Money, Airpay, and Quloi, with a focus on Node.js, AWS, databases, and scalable architecture.

At InCred Money, I engineered dual queues for a multi-tenant bullion trading module, preventing partner rate-limit violations during bursts of 400 orders per minute. I also reduced API consumption by over 70% through price caching while supporting 6,100+ daily transactions.

At Airpay Financial Technologies, I reduced customer-facing API response times from five seconds to 10 milliseconds by adopting Go and redesigning monolithic APIs around cached single inputs. I also led a three-day migration of enterprise transaction logging from Azure Functions to AWS Lambda.

I've decomposed monoliths into microservices, improved deployment speed, built serverless products with Go and AWS, and delivered an AI-powered interactive portfolio designed to present technical work safely and dynamically.
