Ahmed Shamim Hassan
I’ve spent the past ten years building software, from backend services to leading product teams and designing system architecture. Today my focus is AI engineering: building agents and the products that put them to work, like Kinocrew and PulseDeck.
Most recently, I was a senior software engineer at Kahf Yazılım A.Ş. Alongside that work, I write books, teach courses, and mentor developers.
Get in touchThe thinking behind the code
Understanding the problem is part of the engineering work. It’s a recurring subject in my writing and teaching: questioning requirements, finding edge cases, and deciding what to build before writing the code.
I also contribute to the Laravel framework and maintain open-source projects. This site is where I share what I learn along the way.
Books
