ABOUT ME

Sepehr Chahnavi

Game Developer & Software Engineer

Born in 1998, with a bachelor's degree in Software Engineering. I turn ideas into interactive worlds, combining thoughtful engineering with a love for game design.

A little about my work

My work sits at the intersection of technology, design, and storytelling. I build systems that feel responsive and worlds that feel alive, with a focus on the details players always feel: the weight of movement, the rhythm of interaction, and clear visual feedback.

I enjoy solving complex problems, experimenting, and refining ideas. My goal is to create experiences that entertain, educate, and inspire.

THE IDEA BEHIND REDWING

Your game. Your wings.

Your game is your vision and creativity. Your wings are the knowledge, tools, and community that help you bring it to life.

Through Redwing, I share practical lessons and the real development process, from bugs and experiments to breakthroughs, to help other developers build with confidence.
