Kimmang Kim developed the foundational onboarding project for the INNER-CIRCLE-ICD4/onboarding-project repository, focusing on establishing a standardized Spring Boot application scaffold. Leveraging Java, Gradle, and Spring Boot, Kimmang set up the initial architecture with web, JPA, Lombok, and H2 runtime integrations, ensuring cross-platform build compatibility for both POSIX and Windows environments. The work included creating a basic application class and initial test scaffolding, laying the groundwork for early feature validation and regression testing. By defining the repository structure and development workflow, Kimmang enabled consistent collaboration and streamlined handoffs, providing a robust baseline for future onboarding feature development.
