Well done Bukola! This is a great.

To further enhance security, we can consider implementing server-side validation to verify uploaded file integrity and content after it reaches the S3 bucket.

Additionally, defining a whitelist of MIME types ensures that only permitted content types are accepted, adding an extra layer of protection against unauthorized uploads.
