I led the end-to-end data tracking solution for a global telecom company, designing a structured data layer to enhance tracking accuracy. Managed tag management systems like Tealium iQ, Google Tag Manager, and Adobe Launch, setting up Facebook Pixel, Google Ads conversion tracking, and server-side APIs like Facebook CAPI. This solution improved match rates by over 90%, optimized multi-channel tracking, and enabled the analytics team to provide data-driven insights to stakeholders.
