During June 2025, Kim Mang established the foundational architecture for the INNER-CIRCLE-ICD4/onboarding-project repository, focusing on rapid onboarding and consistent development workflows. Kim set up a new Spring Boot application using Java, integrating JPA, Lombok, and H2 for runtime persistence, and configured the Gradle build system to support both POSIX and Windows environments. The work included creating the initial application class and test scaffolding, ensuring early validation and future regression checks. By standardizing the repository structure and build configuration, Kim enabled cross-platform collaboration and streamlined handoffs, laying the groundwork for efficient feature delivery and maintainable onboarding projects.
