Hi there,
I am an expert in back end systems development with more than three years of experience in AWS and Cloud infrastructure. I have developed a similar Cloud Function in GCP before and I can get yours setup quickly. To get started, share the following:
1. Add me to the AWS project with suitable roles so I can develop and deploy the Lambda function (I will need at least Lambda Admin Role if not Admin User Role)
2. Does the original WebP images need to be saved alongside the converted images?
3. Does the name and other meta attributes remain unchanged between the two images?
4. Are there any other requirements?
I can get this done in 2-3 hours time and show you a demo. To get started, message me in chat. Thanks for your time and consideration.
