Passionate about gaming and development, I am opening opportunities for freelance projects. I offer flexible payment terms for clients with a strong reputation, aiming to build lasting professional relationships.

Outside of the game world, I have expertise in AWS services, distributed web systems, GoLang, C++, C, and frameworks like Angular, Vue, and React, but I’m definitely not a designer! xD
