Mike Yan focused on improving data integrity and documentation quality across the SimplifyJobs/Summer2025-Internships and SimplifyJobs/New-Grad-Positions repositories. He updated the README logo image source using Markdown to ensure consistent branding and enhanced the user experience by removing outdated and inactive job listings from listings.json files. Leveraging skills in data management, front end development, and API integration, Mike’s work addressed both visual and data-driven aspects of the projects. These targeted changes reduced user confusion and support queries, resulting in more accurate job listings and clearer documentation. The updates demonstrated careful attention to detail and a methodical approach to software maintenance.
