I design and build large-scale distributed systems and ship full-stack product features — from event-driven backends to modern React/Next.js UIs.
- Built high-throughput gRPC microservices for a global travel search platform (flights, lodging, cars)

- Owned data platforms processing 500M+ product records; drove dashboards to sub-second P99

- Built event-driven billing on AWS (CDK, EventBridge, DynamoDB) and improved reliability with strong service contracts
TypeScript (NestJS + React/Next.js), AWS, Kubernetes, event-driven microservices — plus AI-augmented workflows with Cursor, Claude, skills, and MCP.
