Software I've built.

Local apps in Go, with a browser UI. One binary, shared state across tabs, and no separate JavaScript frontend.

Powers a dashboard, a 3D solar system, an xterm.js terminal running Claude Code, and an ffmpeg-decoded video player, all as single Go binaries. Multi-tab and multi-device sync are properties of the architecture, not features.

A custom backtesting engine built for strategies that stopped fitting neatly inside off-the-shelf Python frameworks.

Built for custom logic, exact indicator matching, portable execution, and large runs across millions of candles.

Planetary positions in Go using NASA JPL data. Ported from a working Skyfield pipeline and validated against it.

Integrated into my own pipeline within days.

A three-part progression from simple decision agents to LLM-powered agents and clarifying loops that ask before acting.

The series walks through rules, perception, and clarification using concrete examples rather than abstract agent hype.

A beginner-friendly series on compiling Quake 3 source and modifying missile behavior to create a homing rocket.

Covers the full path from building the source to changing gameplay behavior and understanding parts of the engine.

A Chrome extension for running SOQL and SOSL queries directly against Salesforce with no intermediate server.

Supports REST-based access, paging, result browsing, and direct querying against the target environment.

A realtime web app stack combining Node.js, Socket.IO, MongoDB, and AngularJS for synchronized client state.

Split into transport, client library, Angular integration, and demo app instead of hard-coding everything into one sample.

A flexible Node.js static site generator I built when existing tools felt too rigid and too tied to someone else's content model.

Created to keep content structure flexible, add generators, and avoid hacking around frameworks just to publish a site.

A sitemap-driven SEO analysis workflow built almost entirely with AI agents, then corrected by hand where the agents drifted.

Started from an empty directory, requirements-first, and shipped a working HTML reporting tool for a real migration need.
