- AWS CDK v2 for infrastructure
- DynamoDB for data, S3 for assets

## Conventions
- Use ESM imports, not CommonJS
- Lambda handlers export a named `handler` function
- Use middy middleware for cross-cutting concerns
- All API responses follow JSON:API format

## Testing
- Unit tests with vitest
- Integration tests with aws-testing-library
- E2E tests use deployed staging environment

KEY DIFFERENCES

1. Config format

2. IDE integration

Goose: CLI. Kiro: Supported.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Goose, configure config.yaml. If you use Kiro, configure .kiro/steering/*.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
