Python & AWS Expert for Scalability Optimization

I am looking for a seasoned Python developer with extensive AWS experience to help me optimize the scalability of my systems. This project primarily involves:

- Optimizing existing systems to make them more scalable
- Focusing on AWS Lambda functions, DynamoDB database, and Step Functions workflows

The ideal candidate should have a strong background in system optimization, particularly in the context of performance, scalability, and maintainability. They should also be proficient in Python and AWS, with a proven track record in developing new features and automating tests.

Please note, this project is not focused on data engineering but rather on development and test automation.
