Fedja Bosnic

Founder | Leader | CTO

I'm a seasoned engineering veteran, turned leadership, turned founder.

In a nutshell:

- Founder of an AI startup

- 10+ years of engineering leadership

- 20+ years of engineering and architecture

My mission is to take the burden of technical complexity away from founders and their creative teams, so that they can focus on building their product.

Open to fractional CTO, engineering leadership and advisory roles.
