Worked on enhancing the mobile user experience for the DivinumOfficium/divinum-officium repository by addressing font size and readability issues on mobile devices. Implemented a responsive viewport strategy using HTML and front end development skills, introducing a conditional viewport meta tag that applies only to the mobile version of the site. This approach allowed users to switch to a desktop view if they preferred smaller text, improving accessibility and user satisfaction. The solution was documented to support future maintenance and audits, demonstrating a methodical approach to web development and a focus on reducing friction for mobile users without introducing regressions.
