About

I am a Unity and C# developer focused on building clean, efficient, and scalable applications and games. I have experience working on 2D and 3D game projects, implementing gameplay systems, and optimizing performance using techniques like object pooling.

I am passionate about game development and always looking to improve my skills while delivering high-quality results. I adapt quickly to new tools and workflows and can work both independently and in team environments.

I’m looking for freelance opportunities where I can contribute technical value and help bring ideas to life.
