As a client with a functioning batch-based application, I'm looking for an expert who can contribute to my project by:

- Implementing cucumber tests with a strong focus on Java Spring Boot and Spring Framework.
- Specializing in data processing, specifically relating to payment transactions.

Ideal Skills:
- Extensive experience writing cucumber tests.
- Advanced proficiency in Java Spring Boot, Spring Framework.
- Practical experience with batch-based applications.
- Previous work with payment transactions data processing is a huge plus.

Please note, the handling of the payment transactions itself is not part of this project.
