Neoh focused on lightweight portfolio prototyping and repository hygiene in the yypang2/SECP1513202420251-09 repository. Over the month, Neoh developed a transient HTML portfolio prototype to evaluate presentation strategies, then removed it after assessment, ensuring the repository remained uncluttered. To enhance documentation and accessibility, Neoh added a Markdown reference file linking directly to the author’s portfolio. The work also included cleaning up empty placeholder files, reducing confusion and maintaining mainline stability. Throughout, Neoh applied front end development skills using HTML, CSS, and Markdown, demonstrating a methodical approach to iterative prototyping and repository management within a short project timeframe.
