At Scapia, I designed and implemented the complete UPI backend, from system architecture through production deployment. It processes 55,000+ transactions daily and more than 4 million cumulative transactions.
I built resilient callback and reconciliation pipelines with AWS API Gateway, SQS, DLQ, and Lambda to support idempotent processing and transaction correctness. I also co-built Scapia Store’s e-commerce backend, covering checkout, orders, refunds, payments, and shipment tracking for 800+ products.
I’ve led backend readiness for a sale handling 20x normal traffic with zero downtime, migrated infrastructure to AWS CDK-managed IaC, and reduced Retool hosting costs by 50%. Previously at Societe Generale, I built .NET Core and React applications and helped migrate projects from .NET Framework.
