Systems Engineer & Polyglot Programmer. Passionate about building high-performance infrastructure from scratch—ranging from raw C embedded graphics engines and C++ multithreaded servers to Rust compilers and autonomous AI simulations. I don't use frameworks; I write them.
C02 (C, Rust)
An optimizing compiler targeting the MOS 6502 8-bit architecture.
- Implements a custom virtual register machine mapping variables to Zero Page memory locations for ultra-low latency execution.
- Features a full custom semantic analyzer, scoping engine (
SymbolTable), and an explicit down-growing software stack pointer in main RAM. - Engineered entirely left-handed post-op during dominant-wrist surgery recovery.
shader-works (C)
A zero-dependency software 3D rendering engine for bare-metal embedded hardware.
- Implements a fully programmable graphics pipeline from scratch, featuring software-defined vertex and fragment shader emulation.
- Handles raw matrix math, coordinate space transformations, clipping, and rasterization entirely on the CPU without native GPU acceleration.
secure-serve (C++)
A custom, high-concurrency, multithreaded HTTPS server built from the socket level.
- Implemented entirely with raw POSIX threads (
pthreads) and native sockets, utilizing a custom-built manual thread-pool architecture. - Features low-level OpenSSL bindings to handle cryptographic TLS handshakes and packet processing directly at the bytecode level without web frameworks.
ai-survival (JavaScript)
A multi-agent, in-browser simulation tracking emergent social and survival dynamics.
- Models autonomous AI agents dynamically interacting within a shared, high-stakes ecosystem.
- Explores finite state machines, multi-variable feedback loops, and unscripted emergent behaviors in real-time environments.
- Languages: C, C++, Rust, Java, JavaScript, ARM Assembly, 6502 Assembly
- Low-Level Dev: Systems Programming, Memory Management, Compiler Design, Embedded Rendering Pipelines
- Networking: POSIX Sockets, Concurrency (
pthreads), TLS/SSL Cryptography
