05. INTERESTS

Chess

I have a genuine love for the game of chess itself—the depth, the patterns, and the quiet contemplation. I spend most of my chess time studying and solving tactical puzzles.

LEGO

I like collecting and building LEGO sets. There is something grounding about stepping away from screens and assembling physical structures brick by brick.

Lindy Hop

I love jazz music and dancing to it. Social swing dancing brings great music, rhythm, and spontaneous connection together in an energizing way.

Cooking

I like trying new recipes, experimenting to understand what makes a dish work fundamentally, and tasting the final result.

Cycling

I like riding my bike along the shore and moving around the city. It’s my favorite way to clear my mind and experience Istanbul at my own pace.

Fitness

I enjoy being alone, fully concentrated, and locked into a consistent routine. It keeps me grounded, disciplined, and physically sharp.
