I write code close to the machine—compilers, kernels, allocators, emulators, runtimes, and quantum circuits. I care about the layers where abstractions stop being free and correctness starts costing real cycles.

Web is where I ship. Systems is where I think. Quantum is the long game.


01 // PRIMARY SIGNAL

qasm-rs

An OpenQASM 3 compiler in Rust with compile-time qubit linearity enforcement.

It treats qubits as linear resources—the quantum analogue of Rust ownership—so use-after-measure errors die in the compiler instead of wasting hardware time.

qubit q;
bit c;

c = measure q;
h q; // error: quantum state already collapsed

02 // FIELD WORK

signal transmission
CappyDisk Native SwiftUI disk visualizer with safety-aware cleanup, a radial map, and explicit metadata-only AI inspection.
zSprite Local-first pipeline that converts short AI animation videos into game-ready transparent sprite sheets.
RustybaraOS A small operating system in Rust, because the best way to understand the machine is to remove the machine's safety rails.
Chip-8-Emulator A C++ emulator built to make fetch → decode → execute tangible.
veryrandom A quantum random-number generator that runs Hadamards and measurements through IBM Qiskit.
ZPT2 A GPT-2 implementation built for learning the machinery behind language models.

03 // TOOLCHAIN

SYSTEMS      Rust · C · C++ · x86 ASM · Linux · Swift
QUANTUM      OpenQASM 3 · Qiskit · IBM Quantum · linear types
COMPILERS    lexing · parsing · semantic analysis · IR · DAG optimization
AI / ML      Python · PyTorch · MCP · model-backed developer tools
WEB          TypeScript · React · Next.js · Node.js · APIs

04 // OPERATING PRINCIPLES

+ make invalid states unrepresentable
+ measure before optimizing
+ keep the sharp edges visible
+ ship the useful thing
- mystery abstractions
- correctness by coincidence

Outside the terminal, I produce and DJ electronic music as Capybara Watanabe. The signal chain changes; the obsession with systems does not.

If you're building something difficult near the hardware boundary, I want to hear about it.
