Zoriana Omelchuk

Zoriana Omelchuk is the Head of Marketing at CAS.AI, where she leads user acquisition, paid traffic strategy, and growth marketing for a portfolio of 200+ published mobile games. With 12 years of experience in mobile marketing, Zoriana has managed multi-million dollar UA budgets across Meta, Google, TikTok, Apple Search Ads, and all major ad networks.

Her core expertise spans paid user acquisition, ASO (App Store Optimization), creative strategy for mobile ads, and ROAS optimization. At CAS.AI, Zoriana oversees the company’s $1M+/month UA investment, working directly with partner studios to identify winning creatives, optimize funnels, and scale profitable campaigns into Tier-1 markets.

Zoriana is a recognized voice in the mobile marketing community. She has contributed to industry discussions at conferences and roundtables, including a recent expert panel on ASO and UA integration in 2025 — exploring how paid traffic and organic optimization must work as a unified growth system rather than separate disciplines.

Her data-driven approach combines A/B testing at scale with deep understanding of ad creative performance, audience segmentation, and cross-platform attribution. Zoriana advocates for treating UA and monetization as two sides of the same coin — a philosophy embedded in CAS.AI’s publishing methodology.
