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.
Designs, builds, deploys, tests, and debugs AWS Lambda serverless apps with SAM CLI, Lambda Web Adapter, event sources, EventBridge, and observability.
Guides AWS serverless and event-driven architectures with Lambda (TypeScript/Python), API Gateway, DynamoDB, Step Functions, EventBridge, SQS, SNS following Well-Architected Framework for APIs, microservices, async workflows.
Builds production-ready AWS serverless applications with Lambda functions, API Gateway, DynamoDB, SQS/SNS event patterns, SAM/CDK deployment, and cold start optimization.

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.
| User need | Action |
|---|---|
| Building a new serverless app | Read architecture.md for pattern selection, then deployment.md for SAM/CDK templates |
| Debugging an error | Read troubleshooting.md — starts with the 5 most common fixes |
| Optimizing performance or cost | Read lambda.md for cold starts and memory tuning, production.md for readiness checklist |
| Configuring event sources (SQS, DDB Streams, SNS) | Read event-sources.md |
| Step Functions, EventBridge, or orchestration | Read orchestration.md |
| Concurrency configuration | Read concurrency.md |
| API Gateway setup | Read api-gateway.md |
| Common anti-patterns | Read the anti-patterns section in production.md |
| Starting with Powertools | Use powertools-handler.py as a template |
| Spans multiple areas | Read the most specific reference first, then consult others as needed |
| File | Content |
|---|---|
| lambda.md | Runtime, memory/CPU, cold starts, SnapStart, layers, containers |
| api-gateway.md | REST vs HTTP API, stages, auth, throttling, mapping |
| event-sources.md | SQS, DDB Streams, SNS, S3, Kinesis triggers |
| orchestration.md | Step Functions, EventBridge rules/pipes/scheduler |
| concurrency.md | Reserved vs provisioned, scaling, ESM concurrency |
| architecture.md | Patterns, reference architectures, service selection |
| deployment.md | SAM/CDK resource types, globals, fast iteration |
| production.md | Readiness checklist, observability, anti-patterns |
| troubleshooting.md | Error → cause → fix for all serverless services |
