Designed and built the end-to-end UPI mandate autopay flow — from mandate creation (local INIT-state persistence, idempotent order handling, LogrefId generation) through NPCI/UNITY registration (encrypted bank calls, lender enrichment) to async callback-driven activation with TPV validation and penny-drop verification — using a pluggable BankAdapter architecture supporting multiple bank integrations without core logic changes; scaled from ~2-3K to 20-25K mandates created daily. Implemented event-driven refund processing on Apache Kafka for payout-based refunds, handling ~5,000 refunds/day: publishing HMAC-signed refund messages with beneficiary bank UPI details via KafkaTemplate, consuming async status callbacks to reconcile refund state, and building scheduler-driven Kafka retries for failure recovery. Created a merchant VPA onboarding plugin — onboarding users on the app and linking their mobile number to a VPA by integrating a third-party API. Reduced API latency by 60% through SQL query optimization, Redis caching, and async processing, improving system responsiveness under peak load. Architected Kafka-based event-driven workflows to decouple critical payment flows, improving fault isolation and service scalability. Automated the loan assignment system and improved observability via centralized logging (Coralogix), reducing manual effort, turnaround time, and MTTR for production issues. Built a scalable file processing pipeline on AWS S3 for merchant data storage and validation; delivered the top-up loan feature for additional credit offerings.
