Netflix's Localization team faced fragmented analytics workflows, duplicated pipelines, and siloed dashboards as the platform scaled to 300M+ members across 190+ countries. The modernization strategy rests on three pillars: auditing and consolidating 40+ dashboards into unified backend pipelines, reducing 'Not-So-Tech Debt' by improving UX and combining audio/text language metrics into a single consumption view, and adopting a 'write once, read many' architecture with centralized business logic tables. Looking ahead, the team is building event-level analytics to capture granular subtitle data (e.g., reading speed) to improve member engagement with localized content.
