I build high-performance systems software in C/C++ - from 3D renderers that run on ARM microcontrollers to multithreaded HTTPS servers built from POSIX sockets. I love working close to the hardware and understanding how things work at the lowest level.

Currently seeking entry-level roles in systems programming, embedded software development, or game engine engineering.

shader-works - Software 3D renderer with zero dependencies Complete CPU-based graphics pipeline in pure C. Renders 3000+ triangles at 40 FPS without a GPU. Successfully ported to ARM Cortex-M4 microcontroller (200MHz, 192KB RAM) with fully functional voxel world demo.

secure-serve - Production-ready HTTPS web server in modern C++ Built entirely from raw POSIX sockets with OpenSSL encryption, dynamic thread pooling, and smart pointer memory management. Features whitelist-based routing and exception-safe resource handling.

Tiny-Serial - Lightweight serial monitor for embedded debugging Minimal alternative to screen/minicom written in 140 lines of strict ANSI C89. Non-blocking bidirectional communication with graceful signal handling.
