Cristian Serb

Blockchain Engineer & Consultant

About

I was a full-stack web-engineer and tech lead for 18 years. I switched my professional focus towards blockchain technologies in October 2017. Since then I've been working on financial products for crypto currencies as well as technologies around blockchain with a product driven approach for developer accessibility.
