Salesforce and AWS Application Developer

I'm looking for a Node.js developer who can work on an application that bridges Salesforce with Amazon S3. The application is to be built on AWS technologies, primarily involving Amazon S3. The key functionalities of the application would include:

- Data integration between Salesforce and Amazon S3
- Automation of data backup and retrieval

The specific data integration requirement between Salesforce and Amazon S3 is to synchronize data between the two.

Ideal candidates should have expertise in:

I'm looking for a professional who can bring these elements together seamlessly to create a robust and efficient application.
