About me

I build at the edge of product and systems.

Cristian Martinez

Based in Bussum, NL.
Originally from Medellín.

Hi, I'm Cristian. For 14 years, I've turned difficult technical problems into products people can actually use.

My work moves between polished React interfaces and the systems beneath them: SDKs, distributed backends, workflow engines, analytics infrastructure, and AI-powered creation tools.

I've helped platforms scale to millions of users, led architectural migrations, built products from zero, and contributed across the full stack. What keeps me interested is still the same thing: understanding how the layers connect—and making them better.
