During the month, contributed front end development and web analytics expertise to the ArthurSeche/eleve6 repository by implementing Google Tag Manager across six key HTML pages. This work involved embedding and updating GTM scripts to establish a consistent analytics infrastructure, enabling comprehensive tracking of user journeys and supporting future event tracking and funnel analysis. The technical approach focused on direct HTML integration, ensuring that each page—such as confirmation, contact, and product views—was instrumented for reliable data collection. No bugs were addressed during this period, as the primary focus was on laying the groundwork for data-driven decision making and marketing attribution.
