Hi, I'm Serkan Korkut. I turn real-world problems into simple, useful products people love using.
I build products that I actually like using, including apps used by millions, development & developer tools, and distributed systems. I love to find a real problem, turn an idea into something useful, and keep learning from the people who use it.
