I'm Pankaj - a Senior Software Engineer who spends his days on systems that move money: the ICICI Bank loan journey at Paisabazaar, Stripe payout infrastructure at Drivelah in Singapore, and Aadhaar/NSDL e-sign flows at Revfin. I started out at TCS building an IAM system for 20,000+ users. Day to day that's Node.js, TypeScript, Nest.js, React and a lot of AWS - Lambda, Step Functions, SQS, SAM, DynamoDB, CloudFront. I've split a monolith into microservices and come out 20x faster at near-zero cost, sharded MySQL to survive high-volume payments, and cut page load times by 70%. Book me if you want to: get hired at a fintech or product company; untangle a backend that's creaking (microservices, event-driven design, payouts, reconciliation, DB scaling); or ship a payments/KYC/lending feature without a six-month detour. I mentor new hires and run design reviews at work, so I'm used to explaining the why rather than just handing over an answer. Come with a specific problem, leave with a specific plan.
