At DiarchGo, I led a zero-downtime migration of a production API from EC2 to ECS Fargate using a six-stage Cloudflare canary rollout. I also fixed an inventory mismatch across checkout services and ERP synchronization by reworking the flow around an existing atomic checkout service.
I designed a distributed stock-transfer system with transactional guards to eliminate a race condition and phantom-stock exploit under concurrent writes. I also built Terraform infrastructure for AWS environments and designed an Inventory Health engine to flag dead stock across 8 stores in near real time.
At Amazon, I architected a GenAI-powered payment intelligence platform that automated 50% of payment data analysis and support-ticket triage. I also worked on payment microservices, including idempotency for fraud evaluations and concurrency controls for refunds, and contributed to Amazon Seller app integrations and features.
