Worked on backend development for the OpenCSGs/csghub-server repository, focusing on code quality improvements rather than user-facing features. Applied Go to refactor conditional logic in deployer.go, inverting conditions to simplify the structure and enhance readability without altering existing functionality. Additionally, removed an unnecessary debug print statement from collection.go, reducing log noise and streamlining maintenance. The approach prioritized maintainability and clarity, laying a foundation for easier future contributions. No bugs were fixed during this period, but the targeted refactoring and cleanup reduced technical debt and improved the overall codebase. Emphasized backend development and code refactoring throughout the project.
