During July 2025, work focused on implementing backend submodule integration within the woowacourse-teams/2025-feed-zupzup repository. This involved introducing a dedicated Git submodule to establish a modular backend architecture, enabling code reuse and clear separation of concerns across external backend components. The integration required configuring submodule paths and URLs, ensuring seamless connectivity and maintainability for future development. By leveraging Git Submodules and backend development practices, the changes laid the groundwork for scalable, cross-repository collaboration. No bugs were addressed during this period, with efforts concentrated on feature delivery and architectural improvements to support more efficient backend integrations moving forward.
