I am a software engineer focused on building robust systems from the ground up without relying on black-box abstractions. Whether it's crafting an x86_64 operating system kernel that can run both Linux ELF and Windows Win32 PE binaries, optimizing chess engines with AVX-512 SIMD pipelines, or solving differential relativity equations in real-time raylib visualizations.
My projects emphasize mechanical sympathy, mathematical rigor, clean architecture, and extreme execution speed.
