Senior software architect, founder, independent builder.
I design software systems and build apps, SaaS products, and games through Buhane Bilgi Teknolojileri, the company I founded.
I'm Ahmet Bütün, a Computer Engineer from Yildiz Technical University with over two decades of passion for building software that matters.
I founded Buhane Bilgi Teknolojileri, the company behind my product work in apps, SaaS, and games. This personal site highlights selected work; Buhane is the authoritative home for the complete portfolio.
My journey spans from crafting security tools like Nova W-SPY to building open-source frameworks like Crexta, and now pioneering AI-driven creative tools. I believe technology should empower people to do extraordinary things.
