Technologies Used

• AWS CodePipeline – Orchestrates the CI/CD process
• AWS CodeCommit & GitHub – Source control
• Amazon ECR – Hosts the Docker image for the Node.js app
• Elastic Beanstalk – Deploys and manages the app environment
• Amazon S3 – Used for storing security policy (referenced in permissions script)
• Python & Boto3 – For automating S3 bucket permissions

Sample Frontend Page

The test.html file includes a simple webpage used during an interview technical demo with Melita Ltd:
