About Ievgen Kavalerov

Product Designer with 12+ years of experience designing and shipping live-service games, specializing in monetization UX, scalable UI systems, and interaction design for measurable growth. Currently working at Prodigy, where I lead design for conversion-critical features such as One-Time Purchases, Unified Store, Bundles, and HUD—contributing directly to multi-million-dollar revenue initiatives and company OKRs.I focus on turning complex product goals into clear, testable, and player-safe experiences, especially for younger audiences. My work combines data-informed UX decisions, high-fidelity prototyping, and production-aware UI design, enabling teams to validate ideas early, move faster, and ship with confidence. Known for bridging design and engineering, improving pipelines, and building reusable systems that scale across features, platforms, and LiveOps needs.
