In April 2025, Alec Ere developed Cognito-based user authentication for the aws-samples/amazon-bedrock-samples repository, introducing a new CognitoAuth construct and integrating it into the project’s deployment pipeline. Using AWS CDK and TypeScript, Alec replaced the legacy username and password login with Amazon Cognito, centralizing identity management and enhancing both security and scalability. The web service was updated to rely exclusively on Cognito when enabled, effectively reducing the attack surface associated with traditional password-based authentication. This work demonstrated a focused application of Infrastructure as Code principles, delivering a robust authentication solution within a short timeframe and with clear technical depth.
