ABOUT

Freelance product engineer with twelve years building and leading startup products as developer, CTO and founder — AI agents, data engines and MVPs, shipped end to end. I bridge design, engineering and business: the same head that scopes a product also builds it. Based in Estonia, working with teams across Europe and the US.
