Batool F. developed enhanced customization capabilities for AWS Config rules within the awslabs/landing-zone-accelerator-on-aws repository. She introduced a new TypeScript interface model for defining Lambda-based custom AWS Config rules, formalizing how custom rules are configured and triggered. Her work included refactoring the existing ConfigRule implementation to support cases where customRule may be undefined, which increased flexibility for optional rule definitions and reduced setup complexity. Batool updated documentation using typedoc to improve type safety and developer experience. Leveraging AWS, Infrastructure as Code, and TypeScript, her contributions provided a more maintainable and adaptable approach to managing AWS Config rules.
