• Led zero-downtime migration of a production API from EC2 to ECS Fargate via a self-designed 6-stage Cloudflare canary rollout strategy, enabling instant rollback and eliminating cutover risk, dropping down our cost by 75%.
• Improved React Native catalogue navigation latency from 500 ms to 100 ms using intelligent prefetching, client-side caching, request cancellation, and a feature-flagged Redis caching layer.
• Diagnosed and fixed a distributed inventory-mismatch bug spanning checkout services and ERP synchronization by re-architecting the flow around an existing atomic checkout service, closing a data-consistency gap across microservices.
• Designed a distributed stock-transfer system across all dark stores and warehouses with transactional guards, eliminating a race condition and a phantom-stock exploit under concurrent writes.
• Designed a near-real-time Inventory Health engine using precomputed worker-side aggregation to identify dead stock across multiple dark stores.
• Built Terraform-based IaC (IAM, ECS, ALB, ElastiCache, observability stack) to provision dev/beta/prod AWS environments end-to-end, closing critical KMS permission gaps.
