Pacific Northwest
Operating systems, firmware that runs on telescopes and 3D printers, and image-processing pipelines for light that's been traveling for millions of years. I work close to the metal — and I like it there.
Featured work
Native C++ open-source World of Warcraft client with a custom Vulkan renderer (originally OpenGL). Compatible with Vanilla 1.12, TBC 2.4.3, and WotLK 3.3.5a servers. Modular C++20 architecture, 80+ releases. 418★ on GitHub. Featured on Hackaday and TechEblog (Feb 2026).
Open-source reimplementation of Apple Macintosh System 7 for modern x86 hardware, bootable via GRUB2/Multiboot2. Written in C; reconstructed from binary analysis with AI-assisted agent orchestration and QEMU verification (3-day reconstruction documented in Zenodo paper). Featured on Hackaday.
A modern capability-based nanokernel operating system. Emphasizes minimalism and clean separation of kernel and userland through Fast Inter-Process Communication (FIPC).
Research & scientific computing
Reproducibility study of Pioneer 10/11 Doppler anomaly analyses using public data — independent verification pipeline in Python.
Peer-reviewed framework (Zenodo, May 2025) for identifying Doppler-invariant technosignatures using distance-aware signal models — proposes a tiered detection model based on a civilization's ability to compensate for Earth's motion.
Zenodo paper (2025) showcasing an AI-assisted framework that reconstructed Apple System 7.1 from binary analysis within 3 days using agent orchestration and QEMU verification.

About
I'm an independent engineer who's spent the last 10+ years building things that run close to the metal — kernels, firmware, image-processing pipelines. A lot of it is open source. Some of it ended up in published papers. Most of it started because I wanted to image one more nebula and needed software that didn't exist yet.

Why I rebuilt geekastro.dev from the ground up — and what's coming next.
Research code, not a finished tool — a U-Net trained against PIPP / AutoStakkert outputs, exploring whether you can get stack-quality detail without keeping every frame.
The Anycubic Kobra Neo ships with a closed firmware on an HC32F460. Here's what it took to get Marlin 2.1.x running on it — TFT, bed leveling, input shaping, the works.
