About

I'm a software engineer with deep expertise in C++, systems programming, and cloud infrastructure. My work spans from building game engines and binary protocol parsers to designing scalable deployments with Docker, Kubernetes, and Cloudflare.

I enjoy tackling challenges at the intersection of performance and architecture — whether that's optimizing virtualization setups, implementing diff algorithms for game engine serialization, or building robust API integrations.

When I'm not writing code, I'm exploring emerging hardware technologies, researching high-performance computing configurations, and contributing to open-source projects.
