About me

I have been working as an IT professional since late 1990s. I had the chance to build a horizontal skillset that allowed me to approach almost any IT related project. Since 2005 my role has mainly been as CTO in different companies, spacing between small ISPs and System Integrators. My main area of interest has been IT Architecture, Network and Data Security and protection.

Since 2017 I am workig on a new platform for Intellectual Property and Copyright assets protection and management and founded a company called Rights Chain. The Company's vision is to create a comprehensive platform for effective management and protection of Intellectual Property and digital assets, as well as facing ethical issues like Reputation and Privacy.

Blockchain use cases vs Blockchain religion

If you are looking for a post where Blockchain is described as the “new disruptive technology” that will change the world, this is not one of it. You will probably find more “don’ts” rather than “do’s” in this post, so if you care to lose some time on it, please, be my guest.
