I’m a Backend Engineer with 3 years building fintech infrastructure, focused on idempotent payout systems, multi-gateway payment integrations, and queue-based transaction processing. At eVitalRx, I designed and built payout and transactions systems handling Rs.4Cr+ ($480K+) in total disbursements and Rs.8Mn ($90K+) in monthly partner settlements.

I’m deliberate about reliability: I build idempotent payment APIs and resilient webhook processing to ensure reliable transaction handling and eliminate duplicate payouts. I integrated Cashfree, Paytm, Easebuzz, and PhonePe by unifying gateway-specific webhooks, signature verification, and settlement workflows, then added automated reconciliation pipelines to validate transactions, payouts, and ledger records before partner impact.

I also enjoy owning systems end-to-end—from schema design to production failure handling—especially where asynchronous processing matters. I built 0Relay, a webhook delivery platform from scratch on TimescaleDB, Redis, and BullMQ, and I’ve used Redis/BullMQ-based asynchronous payout pipelines with retry and exponential backoff to improve reliability during downstream payment partner failures.
