Worked on the mozilla/bigquery-etl repository to deliver an analytics feature upgrade focused on campaign attribution accuracy. Updated the android_app_campaign_stats SQL view to leverage the v2 underlying table, aligning data access with the latest schema and enabling GCLID-based attribution. This change improved the precision of downstream dashboards and business intelligence reporting by ensuring attribution data reflected current methodologies. The work involved careful use of BigQuery and SQL, with a clean, review-friendly approach that documented the scope for future iterations. No bugs were addressed during this period, with efforts concentrated on delivering a targeted, high-impact feature within the analytics pipeline.
