I build products.

I'm Marko Marinovic, a software engineer and founder. I love building products, and I'm at my best on the parts that are hard to get right - the agent that goes off the rails in front of a customer, the system that falls over under load, the bill nobody can explain.

I'm CTO and co-founder of Blank, where I build AI and full-stack software with ambitious companies. Most of my work now is agents. My latest is Totebot, a platform online stores use to deploy assistants that sell and support customers.

The way I see it, the model writes the code now. What's scarce is judgment - deciding what to build, knowing what good looks like, and refusing to ship what isn't ready. The hard problems didn't disappear. They moved.
