About Me

Hi! I'm a Mobile & Blockchain Developer based in Curitiba, Brazil, originally from Saint Petersburg, Russia. I'm passionate about mixing cutting-edge tech with the goal of making a real impact in the world. I'm constantly striving to expand my knowledge, especially in blockchain and software development, always eager to learn and apply new concepts. What excites me most about blockchain is its power to provide economic freedom for everyone. My career goal is to make the world a better place and find success along the way.

Fluent in English 🇺🇸 and Russian 🇷🇺, I'm also conversational in Spanish 🇦🇷, have picked up a bit of Turkish 🇹🇷 and currently learning Portuguese 🇧🇷. My passion for technology extends beyond just work – I'm an active contributor to blockchain meetups and hackathons 🚀.

Outside of work, I enjoy travel ✈️ and photography 📸 as I explore new places. Huge fan of King Gizzard & The Lizard Wizard 🎸 and firmly believe in the importance of privacy 🔒. I'm also fascinated by the advancements in AI 🤖 and where it's taking us.
