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.

About me

I am a Blockchain and Full stack developer. When I work on a project, I strive for excellence and 100% client satisfaction. Having an idea is easy, but being able to turn that idea into a reality is the tougher challenge. You have the idea ready, as well as detailed spec and graphics and etc, but the final missing piece of your app is to bring all of these together with programming. That missing piece is my specialty. With your design requirements and idea, I write the code to combine it all into a fully functioning. Blockchain ✔ Ethereum DApps development - smart contract, web3, metamask integration ✔ Build and Deploy a Solana Smart Contract ✔ DEX and Centralized Crypto Exchange ✔ Web/Mobile Wallet ✔ Crypto Collectible Platforms and Non-Fungible Tokens ✔ Custom dApps ✔ ICO, STO, Blockchain Copyrighting and Whitepapers Full Stack ✔️ React, React-Redux, React Router, Redux-Saga, Next.js… ✔️Vue, Vuex, Boostrap Vue.. ✔️Django,Laravel,Node js
