Built a pre-ranking plugin within the offer-ranking system, serving 1B+ requests daily, to call an index API to detect items co-shippable with a customer’s cart and augments the offer with an incentive amount; targeted a 2-3% unit-share uplift and multi-million-dollar annual shipping-cost savings across 8 international marketplaces. End-to-end implementation of ”Pair and Save” feature swatch for the Multi Offer Display in Amazon Shopping Experience for mobile and desktop in 4 worldwide marketplacess. Verified zero production traffic across metrics and logs over a 2+ week window, then tore down the deprecated region end-to-end (CDK stacks, load-balancer relay configs, certificates, pipeline stages), eliminating a full regional fleet and its recurring operational cost. Shipped a reconciliation Lambda and reusable Java library comparing source and destination records for data replication workflows, with CloudWatch metrics tracking success rate, processed, and failure counts. Programmed an AI-Native on-call analyzer that ingests tickets, logs, and runbooks to auto-generate triage summaries and root-cause suggestions, cutting mean time to diagnosis and easing on-call load. Designed and implemented a CloudWatch-based steady-state validator for data replication workflows, orchestrating composite alarm checks and metric threshold validations via AWS Step Functions.

Engineered the Feedback module using React and AWS Lambda, enabling seamless performance tracking for over 200 employees. Migrated the performance-assessment platform from an always-on to a fully serverless AWS architecture, cutting infrastructure cost by 90% while holding scalability through peak cycles. Restructured and optimized a ColdFusion-based recursive workflow, reducing message delivery time from 120+ minutes to under 35 minutes (70% improvement). Mentored a couple of SDE interns, providing design guidance and code reviews that helped them ship their internship project within the timeline.
