Worked on enhancing cross-platform analytics by integrating Fenix mobile reports into Firefox Desktop broken-site reporting within the mozilla/bigquery-etl repository. Updated SQL views to unify data from both Firefox Desktop and Fenix datasets, enabling consolidated and up-to-date reporting for site issues. Extended Fenix date filtering to cover a more recent range, ensuring analytics reflect the latest user experiences. Leveraged BigQuery, SQL, and data engineering skills to improve data completeness and accelerate root-cause analysis for user-impacting problems. Maintained clear, commit-driven changes with a focus on reliability, while no major bugs were reported during the period, reflecting a stable development process.
