Worked on the ArthurSeche/eleve7 repository to implement cross-page Google Tag Manager integration, enabling analytics tracking and marketing campaign measurement across six distinct HTML pages. Focused on robust analytics deployment by adding both script and noscript tags, ensuring reliable data capture even when JavaScript is disabled. Utilized HTML and JavaScript to update multiple pages, maintaining a clear and auditable commit history throughout the process. The work provided analytics-ready pages, supporting data-driven decisions for marketing and product teams. Emphasized clean version control and traceability, with all changes focused on feature delivery and preparing the site for comprehensive analytics coverage.
