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.
• Website: termplot.com | GitHub: termplot/termplot

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.
• Website: artintellica.com | GitHub: artintellica/artintellica

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).
• GitHub: 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.
