Jan 2024 – Sep 2025
* Owned the end-to-end technical design of PowerBox, an experimentation platform enabling A/B testing across Amazon's grocery business (Whole Foods Market, Amazon Fresh) — for multiple teams, supporting 100+ concurrent experiments * Drove the build-vs-buy decision and architecture for the experiment lifecycle engine; chose an event-driven serverless design (Step Functions + EventBridge) over a polling-based approach to eliminate manual experiment management, reducing launch time from days to minutes * Designed the data model and access patterns for a multi-tenant DynamoDB backend supporting 10+ entity types with complex querying needs — selected single-table design with GSI-based access patterns. * Built the platform's authorization layer from scratch, implementing role-based access control with custom middleware on top of AWS IAM — navigated between Amazon's org-wide auth standards and the team's need for fine-grained experiment-level permissions * Defined the experimentation data contracts (experiment designs, success metrics, guardrail definitions, custom groups) across 3 business units with conflicting metric definitions — resolved ambiguity by designing a flexible schema that let each BU configure custom metrics without platform changes
