Some projects start with a problem I want to solve. Others start because I'm curious whether I can make something work. This is a selection of the tools, products, games, and experiments I've built along the way. Not everything I work on is public, and not everything here is intended to become a product.
An experimental aviation weather workstation built with Rust, Python, and modern web technologies. Inspired by my earlier work in aviation meteorology, Cirrus explores how far an agentic development workflow can take the construction of a complex system.
An experimental flight simulator inspired by aviation, games, and the experience of flight. It's part sandbox, part creative exploration, and part excuse to keep learning how to build games.
A character-driven game about choices, conversations, and the subtle ways people connect.
A tip calculator that became an unexpectedly elaborate exploration of product design and AI-assisted engineering.
A gentle, family-inspired adventure built around exploration, storytelling, and the satisfaction of reaching an ending.
An AI-powered financial coaching experiment that taught me as much about product decisions and distribution as it did about building software. It's an idea I may revisit.
A command-line tool for managing local language models on Apple Silicon, from selecting and downloading models to running them and diagnosing configuration problems.
A version manager for llama.cpp on Apple Silicon, with support for installing, switching, pinning, and benchmarking different builds.
A Ruby library for calculating the position of the sun and moon, moon phases, and sunlight events including sunrise, sunset, dawn, dusk, and golden hour.

# => 2013-03-05 15:02:52 UTCI built an app to help name our twins, using decades of Social Security baby-name data. After all that effort, Meg told me she'd already picked Anna and Cora. Sometimes the simplest solution doesn't need software.
There's more in progress, including work I'm not ready to share publicly. This isn't a complete history of everything I've built.
