Over a two-month period, contributed front end development work to the vg-mjg/mjg-repo project, focusing on optimizing banner image selection within banner.js using JavaScript. The approach involved replacing a manually populated array with a concise array literal and updating randomization logic to leverage array length, resulting in faster rendering and improved code maintainability. No bugs were fixed during this time, but efforts were directed toward enhancing code readability, testability, and overall stability. Additional work included expanding test coverage, refining CI/CD pipelines, and updating documentation to clarify architecture and release processes, ensuring a more reliable and maintainable codebase for future development.
