Stefan Ivanov
The person behind the workSkopje, North Macedonia

I am Stefan Ivanov, the independent engineer behind Stefan X Miami. I am an independent product engineer and creative developer in Skopje, North Macedonia, working worldwide, and I design and build premium websites, web applications and mobile products end to end.

One person owning the whole thing means the person who designs it is the person who builds it and the person who answers for it. There is no handover between a designer who has left and a developer who was not there.
