- Led the design and delivery of a highly scalable badges and urgency system for Fashion Show weekly sales, architecting backend services capable of handling 60–70 million requests weekly and contributing to over $30M in annual revenue. - Developed an optimised "Add to Bag" functionality for low-consideration items like Beauty and Sleepwear collections allow seamless addition from the Product Listing Page. This resulted in a 2.3M$ annualised increase in sales by reducing friction in the shopping experience. - Engineered resilient microservices in Go with Kafka-based asynchronous pipelines, improving system reliability and enabling deep observability through Prometheus metrics and Grafana dashboards. - Optimised performance under peak load, achieving a 30% reduction in P95 response times by refactoring database access patterns and eliminating redundant Kafka retries. - Collaborated cross-functionally to optimise Kubernetes clusters, applying cost-efficient deployment strategies and autoscaling best practices that reduced cloud spend by $3K/month - I led the migration of 120+ microservices from Consul to Harness pipelines, collaborating with the BLR team to adopt GitOps via Argocd. We successfully migrated 425 service versions, raised 2,500 PR's, and made 7,500 commits, modernising CI/CD and reducing manual errors.
