Contributed a modularity enhancement to the spring-projects/spring-boot repository by relocating the mime-mappings.properties file into the spring-boot-web-server module. This adjustment aligned resource usage with its primary consumer, reducing cross-module dependencies and streamlining both maintenance and testing processes. The work was implemented in Java using the Spring Framework, demonstrating backend development skills focused on modularization within a large codebase. By consolidating resource ownership, the change established clearer module boundaries and laid the foundation for future improvements in project organization. The update was delivered through a single, well-documented commit, ensuring traceability and adherence to best practices in version control.
