C++ Backend & Systems Developer
High-performance networking · Game servers · Security-oriented systems
I’m a C++ developer focused on building low-level, high-performance systems including networking libraries, game server infrastructure, and backend applications.
I enjoy working close to the metal — optimizing performance, designing scalable architectures, and understanding how systems behave under load.
