During November 2024, E21220 focused on targeted bug resolution within the cepdnaclk/people.ce.pdn.ac.lk repository, addressing a data integrity issue in student profile links. They identified and corrected the GitHub profile link on the e21220.html page, ensuring it reliably directed users to the correct student profile. Using HTML and front end development skills, E21220 implemented precise updates to the page structure, prioritizing traceability and minimizing risk of regression. The work improved data accuracy and user trust, reducing potential confusion and support requests. All changes were managed with disciplined version control, allowing for straightforward auditing and rollback if necessary, reflecting careful engineering.
