AWS SES, S3 and Lambda Application Adjustment

Description

I am seeking a developer with good experience of AWS SES, S3, Lambdas and DynamoDB to modify our existing AWS email autoresponder application.
The primary task involves transitioning from using an SNS topic when handling an incoming email, to utilising an S3 bucket for storage whilst calling a Lambda application.
The ideal applicant will have good experience with AWS Services including SES and will have ideally worked with rule sets and S3 buckets and their interation with incoming emails to SES before.
