Figuring Out GitHub OIDC for AWS Deployments

I've got my AWS infrastructure working pretty well. Frontend deployed to S3 with CloudFront, backend APIs with Lambda and DynamoDB, visitor counter incrementing nicely. But I'm still doing everything manually - running ./deploy.sh for the frontend and terraform apply for the backend.

Implementing GitHub Actions OIDC for AWS CI/CD

I wanted to automate deployments using GitHub Actions instead of running manual scripts. OIDC authentication eliminates the need to store AWS credentials in GitHub secrets while providing secure, temporary access tokens. While this is more complex than manual scripts, it mirrors the constraints of production CI/CD environments.
