Objective
Engineer with 30 years of software development experience, from React components
in TypeScript, to shaders in WGSL, to cryptography in Rust, to data analysis in
Python, to device drivers in C, currently 100% focused on artificial
intelligence and machine learning. Seeking to leverage high-breadth
cross-discliplinary expertise in physics, mathematics, and engineering to
contribute code in TypeScript, Rust, Python, Lua, Nushell, and WGSL for advanced
AI systems as a full-stack software engineer at a leading AI company in the San
Francisco Bay Area.
Current Projects (AI & Machine Learning Focus)
Nutorch: PyTorch-like Interface for Nushell
- Developed a Nushell plugin in Rust, wrapping tch-rs (which itself is a wrapper
for libtorch, the C++ library behind PyTorch), enabling a PyTorch-like data
analysis experience directly on the command line in Nushell.
- Offers seamless integration with command-line tools via Nushell’s structured
data pipes, providing a compelling alternative to Python data analysis for
anybody who spends their time in a terminal.
- Tech stack: Rust, Nushell, Python, tch-rs, libtorch, PyTorch.

Termplot: Advanced Terminal Plotting Library
- Created a terminal plotting tool using web technologies (Plotly.js, React
Router, Express, Puppeteer) to render high-resolution, full-color plots as
images in any iterm-compatible terminal via ANSI escape codes.
- Designed for compatibility with Nutorch and other CLI tools, enabling a
complete data analysis workflow in the terminal, from data generation, to
processing, to reduction, to visualization.
- Tech stack: TypeScript, React, Plotly.js, Express, Puppeteer, ANSI escape
codes.

Chatvim: Chat with Markdown in Neovim & CLI
- Built a developer tool for AI-powered chats with Markdown files: a Neovim
plugin (Lua) and a CLI tool (TypeScript). Why markdown files? Because it
maximizes compatibility with existing editor and terminal tools.
- When combined with a customized Neovim configuration and command-line
configuration, it provides an extremely fast interface for inputting and
outputting instructions and code with LLMs, enabling a significant speed
advantage over web-based chat interfaces. Although not (yet) agentic, the
speed advantage is comparable to agentic tools like Claude Code and Gemini
CLI.
- Tech stack: Lua, TypeScript, Neovim, xAI/OpenAI/Anthropic, CLI.
- Website: chatvim.com | GitHub:
chatvim/chatvim.nvim &
chatvim/chatvim.cli
Hallucipedia: Collaborative AI-Generated Encyclopedia
- Founded a Wikipedia-like platform where all content is AI-generated (using
xAI/OpenAI for text and images), allowing users to create linked articles for
a small fee.
- Tech stack: TypeScript, React, React Router, Node.js, Express, tRPC,
PlanetScale, MySQL.
- Website: hallucipedia.com
Artintellica: Free Machine Learning Educational Resource
- Authored (partially with AI) a comprehensive open-source resource with 100+
blog posts and 200+ code demos/exercises on machine learning, neural networks,
deep learning, and reinforcement learning.
- Tech stack: TypeScript, React, React Router, Node.js, Python, PyTorch, NumPy,
Matplotlib, xAI/OpenAI/Anthropic.

Pow5: A GPU-Based Proof-of-Work Algorithm for EarthBucks Blockchain
- Designed a new proof-of-work algorithm for the EarthBucks blockchain,
leveraging WebGPU to enable fast, parallelized mining on consumer GPUs, while
still being fast and cheap to verify on CPU. Significantly faster, more
efficient, and orders of magnitude easier to verify than the previous
Proof-of-Work algorithm for EarthBucks called algo1627 (which was written with
TensorFlow.js and which I also created).
- The algorithm is implemented in WebGPU Shader Language (WGSL), and wrapper
code in TypeScript for the WebGPU web API, allowing the shader to run in
Chrome-based browsers (and soon Safari/Firefox), making it accessible to all
users.
- Features first-of-its-kinds implementation of Blake3 hashing algorithm in
WGSL. Great care was taken to manage memory to optimize performance.
- Tech stack: TypeScript, WebGPU, WGSL, Rust/WASM (used for testing).

earthbucks/earthbucks
WebBuf: Fast Buffer Utilities for Cryptography
- Engineered a high-performance buffer utility library in Rust (compiled to
WebAssembly, wrapped in TypeScript) for hex/base64 encoding and cryptographic
algorithms (SHA256, Blake3, secp256k1, AES256, CBC) across Node.js, Bun, Deno,
and web.
- Enables isomorphic cryptography between server and browser with full typing
and speed optimizations (thanks to Rust/WASM).
- Tech stack: Rust, TypeScript, WebAssembly, Node.js, Bun, Deno.
