Backend engineer and Tech Lead, payments infrastructure (Bengaluru)
7 years at Setu (acquired by Pine Labs) building UPI infrastructure, from a 3-person founding team to 77M transactions a month. I work on systems that can't lose money: idempotency, reconciliation, low-latency ACK paths, and NPCI/RBI compliance.
