Over nine months, Jacob contributed to IllinoisRef/mechref by building and refining interactive educational web features, focusing on structural analysis, course navigation, and documentation workflows. He developed reusable Astro and JavaScript components, such as image carousels and dynamic navigation menus, and enhanced search indexing to improve content discoverability. Jacob modernized course content delivery by converting LaTeX and Jupyter Notebook materials into maintainable Astro components, while also implementing real-time LaTeX rendering with MathJax. His work included UI/UX improvements, codebase restructuring, and robust scripting for deployment and CI/CD. The result was a more maintainable, user-friendly, and scalable educational platform.

Sep 1, 2025September 2025 – IllinoisRef/mechref: Stability-focused month with no new user-facing features. Main accomplishment: hardening the navbar against CSS encoding issues by reading CSS files with explicit UTF-8 encoding, preventing potential rendering failures. This was implemented in the navbar script and tracked in commit 65b1191ed755abe1fece8eaa16be58d00216f382 (cbtf scripot).
