• Deep on the signal side: EMQ, CAPI, server-side events, deduplication.
• Comfortable with Advantage+ and broad targeting.

Strong pluses: TikTok Ads; APIs / MCP tooling to build your own reporting; working alongside a creator or UGC program; health, fitness or nutrition apps; Apple Search Ads or AppLovin; having taken an account through a major signal change.
