About

With 13+ years in game development, I bring deep technical expertise and leadership across mobile and PC. I began as a Unity Developer, advanced to Team Lead, and later CTO—guiding teams through all stages of game development, from prototyping to live ops.

I specialize in team leadership, project planning, and building internal tools that streamline workflows and boost productivity. I’ve developed reusable code packages, automated build systems, and a flexible Unity-based framework that became the studio’s foundation.

As CTO, I focused on hiring, mentorship, and fostering a strong dev culture through clear documentation and best practices. My work aligns tech strategy with creative and business goals, with a strong focus on multiplayer systems, performance, and efficient pipelines. I lead with collaboration, innovation, and a passion for great games.
