Kenan Duman
ABOUT / THE PERSON BEHIND THE SYSTEMS

Twenty years of building.
Still asking what’s next.

I’m Kenan Duman—a founder and software engineer who works across the product, the interface and the infrastructure.

PERSPECTIVE

Ownership across the stack.

My career has taken me through product teams, senior engineering roles and technical leadership. Today, I am building Tournament Suite: a platform for operators who want to create their own competitive communities.

I enjoy the work between disciplines. Translating a business problem into a useful product. Turning a product promise into clear system boundaries. Making the interface and the background workflows part of the same design.

My portfolio spans esports, commerce, AI-assisted education, media processing and mobile applications. The common thread is end-to-end responsibility for how a product works.

The complete journey.
