Hi, I'm Sinan Kalac

I'm a web developer and trained application developer from Osnabrück, Germany, focused on modern web technologies such as Next.js, React, TypeScript and TailwindCSS. I enjoy building clean, responsive interfaces, data-driven components and maintainable frontend architectures. Besides web development, I work on game development experiments, pixel art and small C/raylib prototypes.
