At Zomato, I build financial infrastructure that handles high-volume billing, invoicing, payouts, and accounting workflows. I’ve delivered a regional migration across 14 ECS services, 55TB of DynamoDB, and 2TB of RDS, reducing backup costs by 60% and saving $1M annually.

I’ve built a multi-tenant gRPC invoice platform processing 50L invoices daily and reduced processing time from 24 hours to 15 minutes. I work across Java, Go, AWS, distributed systems, Kafka, SQS, and event-driven architecture, while mentoring junior engineers and owning systems end to end.
