Projects & Volunteer Work

2026

Prodspector

LLM-powered product analysis tool; ingests codebases and telemetry to produce data-enriched user workflow maps & testing infrastructure.

2026

Doggo

Multi-tenant platform for non-QM mortgage lending, serving freelance professionals and international borrowers that conventional underwriting turns away.

Private beta.

2026

Terpsichore

Version control and collaborative editing for sheet music, built for musical theater professionals. Diffs scores semantically rather than by file, over a canonical model whose every element carries a stable id, and round-trips MusicXML against real Sibelius and Finale exports. Part-book assembly is in design.

2024

We Tell Our Selves

Non-profit funded by the Melinda Gates Foundation, built on provisional patent RDRP-001-US-PPA1, "Determining Impact of Content on an Audience." Combines sociological research, machine learning, and direct audience feedback to measure which styles of argument actually move a reader to act.

Tools & Experiments

cloxy

Routing proxy between a local IDE and remote LLM providers. Records the structural skeleton of every request—never its content—to inform local tooling. Built to mitigate breaking changes in IDE request formats, where an intra-workday Claude Code update silently degrades local request profiling.

Written in Go. Built to profile my own usage of LLMs.

zhanki

Anki flashcard deck management suite: processes unstructured tutoring notes into vocabulary flashcards, with video and conversational transcript ingestion in progress. Graphs character relationships—which component of a character carries its sound, which carries its meaning—and groups near-homophones into interference sets to assist with learning.

Built to assist my 22-year journey learning Mandarin.

Lair

Godot game built on top of a C# simulation core. Indirect-management colony sim: carve a base out of a mountain, run an autonomous workforce with its own needs, fund it through asynchronous map actions, and survive waves of opposition.

Exploration of game design and first real usage of the Godot engine.
