Worked on the ArthurSeche/eleve6 repository to deliver three new features focused on analytics, privacy, and user interface improvements across a static HTML site. Implemented Google Tag Manager integration using JavaScript and HTML, enabling comprehensive analytics and conversion tracking on seven key pages. Enhanced privacy compliance by integrating a privacy management SDK, loading the necessary script on hello.html to support regulatory requirements. Improved the user interface by adding class attributes to links for better styling, targeting, and accessibility. Maintained codebase hygiene through consistent updates and clear commit documentation, supporting future maintainability and traceability. No major bug fixes were recorded.
