About me
I am a passionate researcher with internationally recognized publications in economics and technical disciplines, but also mathematics. Most of my work has been published under pseudonyms and some of it was never credited to me or to any of my pseudonyms, when it was contributed in a context of a University team. I hope no one has to suffer such a fortune, ever. I have also studied for two years object oriented software development with Java. In addition, I offer fee and commission based services as a crypto-consultant (btc, altcoins, etc.). You may check out my web site @ https://cryptoconsultant.services/ Currently, I look for opportunities in relevant technical fields.
