AWS Serverless

Overview

Domain expertise for building serverless applications on AWS. Covers Lambda configuration, API Gateway debugging, Step Functions orchestration, EventBridge patterns, event source mappings, concurrency tuning, cold start optimization, deployment with SAM/CDK, production readiness, and troubleshooting across all serverless services.

Works best with the AWS MCP server — enables running CLI commands, querying CloudWatch, and validating configurations directly. All guidance also works with standard AWS CLI access.

Note: Reference files contain specific runtime versions, quota values, and feature matrices that may change. When precision matters (e.g., deploying to production, choosing a runtime, or checking a quota), confirm values against current AWS documentation rather than relying solely on the values in these files.
