Freelance Web & Game Developer
Ukraine (remote)
Started my professional path by building both web applications and graphics-heavy game projects. I moved between PHP, MySQL, JavaScript, HTML/CSS, Apache, and Unix on the web side, then C/C++, DirectX, and OpenGL closer to the hardware - an early foundation for the cross-stack engineering work that followed.
