Core Experience

• Client- and server-side tracking using Tag Management Systems such as GTM or Tealium
• Implementation across core Analytics and Mar/AdTech platforms, including GA4 / GA360, Google Ads, Microsoft Ads, SA360, and social pixels (Meta, Snap, Reddit, etc.)
• Implementation of Conversion APIs (CAPI) and Enhanced Conversions
• First-party data capture to support server-side and API-based tracking (e.g. click IDs, aggregated identifiers, hashed PII, device identifiers)
• Mobile measurement using MMPs such as AppsFlyer, Adjust or Branch, alongside app tracking technologies like SKAN, Firebase and vendor SDKs
• Producing post-change impact analysis strategies for tracking updates, bug fixes and measurement enhancements
• Consent management platforms and consent handling, including Google Consent Mode
• Conducting tracking audits and making clear recommendations to improve measurement accuracy
• Troubleshooting tracking issues across multiple platforms and environments
• Experience with CDPs such as Segment, and analytics tools like Amplitude or Mixpanel
• Configuring data pipelines for event-based data ingestion into warehouses or data lakes

Ways of Working
