Deep technical expertise across infrastructure components - storage (S3, RDS, DynamoDB), caching (Redis), search (OpenSearch), and event-driven systems (Kafka) - with the ability to reason across org-level goals, architectural trade-offs, and component-level details. These large-scale efforts will involve collaboration across numerous backend, infrastructure, and security teams and cross-functional stakeholders, prioritization, decision-making, tracking execution, and driving operational excellence.
