At Zeta, I work on end-of-day financial processing on Apache Flink, coordinating fees, interest, NPA-risk checks, and daily account updates through parallel DAG workflows.

I enabled disaster recovery for fee processing by replacing live API and database dependencies with command inputs for incident replay. I also fixed a repayment state-machine defect and reprocessed 30K stuck repayments.

At EpiFi Technologies private limited, I built a debit-card forex refund system that processed 80K refunds per month worth INR 1 Cr+. I also owned the end-to-end credit-card onboarding flow and onboarded 15K users.
