Hi, I’m Martin Pramatarov. I have two degrees, a Technician of Computer Networks and an MBA (Master of Business Administration). My passion is storytelling, but I can’t hide my nerdish side too. I never forgot my interest in the Hi-tech world. I have 10 years and thousands of articles written about DNS, cloud services, hosting, domain names, cryptocurrencies, hardware, software, AI, and everything in between. I have seen the Digital revolution, the Big migration to the cloud, and I am eager to write about all the exciting new tech trends in the following years. AI and Big Data are here already, and they will completely change the world!

I hope you enjoy my articles and the excellent services of ClouDNS!
