Summary
UX designer crafting meaningful player experiences across multi-platform and mobile games. At Sperasoft, I worked on the UX design of a co-op shooter and led a team of 3-5 UX/UI designers on live ops for two mobile titles. With a Master’s in Human-Computer Interaction, I specialize in creating effective, flexible design systems built on solid information architecture and seamless user flows – fostering player trust and engagement. I’m also involved in hiring, mentoring, and business development while expanding my expertise into game production.
Work Experience
Lead UX Designer @ Sperasoft, a Keywords Studio
Sperasoft is a game co-development company headquartered in California. We work closely with our partners to deliver high-quality titles for world-class publishers. Sperasoft is a part of Keywords studios, an international technical and creative services provider to the global video games industry and beyond.
Projects I worked on:
- "Rainbow Six: Extraction" (Ubisoft, 2022):
- Co-developed a variety of UX/UI features, including Communication Wheel, Mark&Ping System, After Action Reports, and Tutorials;
- Contributed to utilities such as friends list, onboarding menus and accessibility settings.
- "Mortal Kombat Mobile" and "Injustice 2 Mobile" (NetherRealm Studios):
- Designed a large number of features such as Team Presets, Battle Pass, Collection, Combat HUD, Store, Survivor Game Mode and so on. Most of them resonated the players and have had a positive impact on the project performance;
- Led a team of 3-5 UX/UI designers working on both projects for 2 years. We developed quality-of-life features and assisted the game design team.
In addition to my design responsibilities, I am also involved in hiring and business development activities.
As a co-developer/outsourcer working not with just art assets but more sensitive product- and development related information, my portfolio is strictly limited by NDAs and cannot be public, but I am allowed to talk about my challenges and solutions in general, avoiding specific details.
