About me

I’m a Unity game developer with over 3 years of professional experience in software development and 5 years specializing in mobile and pc game development. I’ve worked remotely on fast-paced projects for international teams, where I was often tasked not just with development, but also with testing, debugging, and building reusable systems that supported the entire team.

My portfolio includes published titles such as Hit Perfect 3D, My Little Universe Rail Master Tycoon: Idle Train, where I contributed to both gameplay systems and quality assurance. These projects challenged me to balance creativity with technical precision—ensuring games were not only fun but also stable, optimized, and player-friendly.

Beyond coding, I’m deeply interested in game systems design, player psychology, and creating engaging user experiences. My background has given me a strong understanding of how mechanics, progression, and feedback loops keep players coming back, which I aim to refine further as I grow into more senior roles.

Outside of work, I’m committed to personal growth—whether it’s building communication skills, overcoming challenges like stuttering and anxiety, or pursuing goals like fitness. Just as in game development, I see every step as part of a bigger progression system: learn, adapt, and level up.
