Senior Level Designer with experience in developing mobile games across Adventure, Match-2, Match-3,
Bubble Shooter, and Domino (Solitaire) genres. Over 6 years of experience and 5,000+ level mockups
created.
I specialize in level design, difficulty balancing, prefab creation, player interaction logic, and the
integration of backend mechanics in Unity.

I have hands-on experience with the full cycle of level development: from concept and prototyping to final
tuning, analytics, and player retention optimization. I have a solid understanding of the needs of live
projects and how to work within production teams.
