About me

Former game developer transitioning into traditional software engineering, with hands-on C# experience, production Unity engineering background, and a growing focus on backend architecture. I am now building full-stack systems with ASP.NET Core, Entity Framework Core, PostgreSQL, React, Docker, and AWS, while carrying forward the performance mindset I developed from gameplay, rendering, asset loading, and mobile optimization work.
