Go to Lead Game designer

Lead Game designer

Mainly working for Ubisoft, I led successful game design teams, designed AAA games from conception to release on 7 different platforms (Assassin’s Creed, Immortals Fenyx Rising, The Crew), and developed Live plans drastically increasing ARM and player engagement.

Go to User Experience Director

User Experience Director

Currently UX Director for Ubisoft, I have always strived to deliver the best possible user experience to my players: following trends, creating cohesive designs and directions, and testing with end-players at every step of the way. I also created UX guidelines in trainings used worldwide in Ubisoft.

Go to Creator of

Creator of

Gdkeys is a design community of published indie developers, AAA designers and students, focused on learning and supporting each others games and projects in an open manner. This is where I also share the tools and knowledge I hope I had access to when I started in the industry.


I also make the best crepes!
Players Focused Common Sense

Currently working in Ubisoft Bucharest, Romania, as a UX Director on an unannounced project.

Having worked in so many fields and for such great projects and teams allowed me to really become a versatile designer. Over the years, I've had to be producer, Live-game expert, lead, and of course: UX expert and game designer. This is what the projects presented here try to picture.

Following the - Form follows Function - mantra, I have been putting the players at the center of my design process, through studies (behavior, demographics...) and playtests (AB testing, focus groups...).

Finally, having lived and work abroad for 6 years, from Bulgaria, to Japan, Australia, Spain and Romania, I believe I became a very open-minded person, able to adapt fast in any kind of environment or project.
