In August 2025, Jaewu Chun enhanced the nwplus/portal codebase by upgrading the Markdown rendering in the HackathonInfo component. He replaced react-html-parser with react-markdown, streamlining dependencies and introducing a more specialized markdown processor. This frontend development work, implemented using JavaScript and JSX within a React framework, preserved existing formatting while simplifying the rendering pipeline for future improvements. By maintaining UI consistency and reducing reliance on general-purpose libraries, Jaewu set a foundation for easier maintenance and extensibility. The depth of this contribution lies in its targeted scope, addressing both immediate technical needs and long-term codebase sustainability without introducing regressions.
