Worked on the alphagov/govuk-design-guide repository to restore analytics tracking by correcting the Google Tag Manager container ID, ensuring accurate data collection for dashboards and analytics pipelines. Addressed a critical bug affecting data-driven decision-making by validating that user interactions and events were properly captured after the update. The solution involved configuring GTM, validating analytics data, and managing the release through Git, all while collaborating with analytics and product stakeholders to confirm alignment with business goals. Demonstrated skills in analytics integration, front end development, and cross-functional communication, delivering a low-risk configuration change that improved the reliability of product insights and reporting.
