Hello, I'm Berk, an experienced C# Unity developer with a strong background in developing 2D, 2.5D, and 3D games, as well as creating effective tool packages and scalable gameplay systems. My expertise includes gameplay programming, software architecture, optimization, debugging, and building maintainable systems based on SOLID and OOP principles. Throughout my game development journey, I have focused heavily on writing clean, reusable, and scalable code while maintaining strong performance standards using tools such as Unity Profiler and Frame Debugger. I also approach development with a problem-solving and test-driven mindset. Before transitioning fully into Unity development, I gained solid experience with .NET, ASP.NET Core, MSSQL, and MySQL, which strengthened my understanding of backend systems, scalable architectures, and data-driven applications. In recent years, I have also been actively exploring AI-assisted development workflows using tools such as Codex and Claude to improve productivity, architecture planning, debugging, and development efficiency. I enjoy learning new technologies and adapting modern workflows to improve both software quality and development speed. Additionally, I have expanded my expertise into VR development and Unity ECS/DOTS methodologies to stay aligned with modern industry trends and high-performance game development practices. I also run my own company, Terek Gaming OÜ, a private limited company registered in Estonia, which enables me to collaborate on a B2B basis with partners and clients across Europe. I am enthusiastic about the opportunity to contribute my technical skills, problem-solving mindset, and passion for development to your team. Best regards, Berk Terek
