Senior Software Developer at Delhivery; owned Orion for FTL billing and vendor reconciliation.

At Delhivery, I owned Orion, a vendor receivables/payables platform for FTL operations, from architecture through production reliability. I built invoicing, vendor onboarding, and charge-review workflows, and moved notifications to an asynchronous Kafka-consumer architecture.

I also led a zero-downtime migration of 22 services and data stores from Singapore to Mumbai, and improved P99 latency across 30+ APIs by 50–90%. At Spinny, I built inspection APIs and workflows, improved async task reliability from 85% to 99.8%, and reduced MySQL response times by 30%.
