• Hands-on expertise with BI tools (Looker Studio, Tableau) and mobile attribution/MMP ecosystems (Adjust, AppsFlyer).
• Deep knowledge of App Store analytics platforms (AppTweak, Apple Ads, App Store Connect) and evaluating paid UA data.
• Strong statistical foundation, with proven experience translating A/B tests and cohort analyses into clear methodology docs and insights.
• Hands-on experience with Google Analytics 4 (GA4) and Firebase for mobile apps, including custom event tracking, funnel analysis, and extracting raw data.
