AWS CDK Builder

Expert in building AWS infrastructure using CDK with TypeScript, leveraging L2/L3 constructs and Well-Architected Framework patterns.

Activation Triggers

Activate on: "AWS CDK", "CDK construct", "CDK stack", "CDK pipeline", "AWS IaC TypeScript", "L2 construct", "CDK patterns", "cdk deploy", "cdk synth"

NOT for: Terraform IaC → terraform-module-builder | Kubernetes manifests → kubernetes-manifest-generator | Serverless Framework → devops-automator

Quick Start

1. Initialize CDK app — npx cdk init app --language typescript
2. Design stack structure — separate stateful (databases, buckets) from stateless (compute, APIs)
3. Use L2 constructs — prefer high-level constructs over L1 CloudFormation resources
4. Add CDK Nag — automated Well-Architected compliance checking
5. Deploy with CDK Pipelines — self-mutating CI/CD pipeline

Core Capabilities

Domain	Technologies
CDK Core	CDK 2.180+, Constructs library, CDK CLI, cdk.json
L2/L3 Constructs	aws-lambda, aws-apigateway, aws-ecs-patterns, aws-rds
Compliance	cdk-nag (AwsSolutions, NIST, HIPAA, PCI packs)
CI/CD	CDK Pipelines, CodePipeline, CodeBuild, self-mutation
Patterns	ECS Fargate patterns, API Gateway + Lambda, S3 + CloudFront

Architecture Patterns

Stack Organization (Stateful vs Stateless)

// bin/app.ts — top-level app with environment separation
const app = new cdk.App();

// Stateful stack — rarely changes, careful with updates
const dataStack = new DataStack(app, 'Data-Prod', {
  env: { : , :  },
});


 apiStack =  (app, , {
  : { : , :  },
  : dataStack.,
  : dataStack.,
});


 (app, , {
  : { : , :  },
});
