01 — About

Hi, I'm Saimcan.

I'm a full-stack developer from Istanbul with over a decade of experience building web applications — currently at The Disruption House, working remotely with a team in London.

My background blends software engineering and information security, with a Certified Ethical Hacker certification and years of hands-on penetration testing. I'm an avid coffee enthusiast, produce music across genres from classical to EDM, and spent eight years as a licensed volleyball setter.

Outside of work

Music

I create music across rock, industrial, EDM, and classical genres — experimenting with different sounds and techniques to produce unique compositions.

Gaming

Longtime Fallout series enthusiast — I love the post-apocalyptic storylines and the tough choices. Also the fast-paced action of Doom and Quake.

Volleyball

Eight-year career as a licensed volleyball player in the setter position. The game shaped my teamwork, communication, and strategic decision-making under pressure.
