Worked on initializing the INNER-CIRCLE-ICD4/onboarding-project repository by delivering a foundational Spring Boot application using Java 21 and Gradle. Focused on creating a reusable bootstrap pattern that streamlines setup for future onboarding projects, the work included establishing a standardized build configuration and test scaffolding. The project structure was validated with initial tests, ensuring compatibility with CI/CD pipelines and supporting maintainable development practices. Emphasized quality and clarity in both application and test classes, demonstrating effective use of Spring Boot 3.5.0 and Gradle. This approach reduced setup time and provided a consistent technical foundation for subsequent onboarding initiatives.
