• Architect reliable webhook and event-driven integrations with idempotency and retry mechanisms. 

• Design highly available AWS infrastructure using API Gateway, ALB, Auto Scaling, and RDS. 

• Establish API standards and OpenAPI specifications for parallel development. 

• Enforce coding standards, perform architecture reviews, and mentor engineering teams. 

• Design, build and manage CI/CD pipelines for automated cloud deployments.
