About

I am a .NET Backend Developer specializing in C# and modern backend architecture. I build reliable REST APIs, microservices, authentication systems, and database-driven applications using ASP.NET Core, PostgreSQL, Docker, Redis, and distributed communication technologies such as gRPC. I enjoy improving performance, writing maintainable code, and delivering backend solutions that support real users and business needs.
I have worked on enterprise web applications and multiplayer mobile game services, including systems supporting more than 50,000 active users and 200 concurrent players. I am comfortable collaborating in Agile teams, contributing to code reviews, configuring CI/CD pipelines, and writing automated tests. I am always eager to take on challenging projects and continue growing as a backend engineer.
