• $250K a year cut from infrastructure spend across Finance, Brand, Seller, Contracts, Eywa (multi-agent platform), and Supply Chain, through workflow redesign and right-sizing.

• The backend monolith retired: workflows moved to microservices across 12 teams and 3 stacks.
• MongoDB moved from Atlas to self-hosted EC2 with no read downtime — under a 10-second cutover, $20K a month saved — on a migration library written for the job.
• 500+ stability, fallback, observability, and P0 fixes landed across the vertical.
• Prism (procurement, invoicing, spend) and Athena (central approvals rule engine) shipped — now how Zepto approves spend, purchase orders, layouts, and pricing.
• Agentic AI workflows ship through CI/CD, so non-deterministic changes roll out with the same safety as code.
