John Barro focused on foundational engineering work across two repositories, Anthoniemous/BSIT-2A-1st-Sem-2025 and Anthoniemous/BSIT-3A-IPT2, over a two-month period. He removed obsolete frontend code and legacy PHP pages to streamline the codebase, reduce maintenance overhead, and mitigate security risks, laying groundwork for future UI modernization. In parallel, he established a clean documentation scaffold using Markdown and HTML, standardizing README structures and eliminating unused files to support clearer onboarding and contributor guidance. His work emphasized codebase hygiene and documentation clarity, leveraging CSS, HTML, and PHP to create a maintainable, well-documented starting point for ongoing development.
