Fullstack Developer, Digital Nomad and Crypto Enthusiast
About Me
I started as a desktop developer in a small Siberian company, after which I had the opportunity to work on several high-load systems for global companies in Russia, Germany, and Australia as a backend developer and team lead. I believe that a technical background is merely a support for solving the most complex business product challenges.
