PlateMath

PlateMath is a power-user workout tracker that logs all PRs and lifting metrics, with fast keypad input or CodeMirror-style syntax input for jotting sets. It generates any exercise from a movement + modifier system, tracks fractional sets and bodypart volume, and computes rolling averages and other metrics. Users can build and import training programs using a syntax language.

YouTube Sub List Viewer + TV Scheduler

This app is a YouTube subscription list viewer and TV scheduler that lets users build and share custom YouTube TV stations. Its primary table view supports double column sorting, and middle-clicking the title column queues a playlist based on the current sort, generating a playlist of a set duration modified by playback speed with options like skipping watched videos, making it easy to stay up to date with your own subs. It can boot into a TV mode, and setup uses a Google Sheet with Apps Script so the user's own YouTube API quota is accessed; syncing between devices costs a nominal fee.

kuluu-ffxi

A faithful reimplementation of the Final Fantasy XI retail client (~0.9:1) that eliminates the original's performance jank and cruft while adding cross-platform support, with a plugin system and hackable source code that lets players layer on optional quality-of-life, graphical, and UI/UX improvements or build entirely new experiences across various private servers.

alint

A general repository linter that lets teams declaratively define rules and conventions for their repos beyond what language-specific linters cover, including checks for directory structure, required files, file staleness/freshness, file size, binary files, and invisible Unicode, all checked deterministically. It packages the hand-authored scripts large repos typically use for these checks into a fast, reusable, and extensible tool.

Pessimal

A disk-space monitoring stack for headless VMs: a minimal OpenTelemetry agent sends VM metrics to an OTel collector (Signoz for now), and an iOS/macOS app queries the metrics at regular intervals. It works with an existing Signoz instance at no extra cost, Honeycomb and Clickstack compatibility is untested so far, and the apps are currently in private TestFlight.

Willikins

A CLI tool that deterministically provisions new projects’ supporting infrastructure — git repository, secrets vault/config, build pipelines, and more — based on the project’s needs (CLI tool, web service, mobile app, etc.). It is very much in progress but has already forced some config cleanup.

VentureRanker

A wizard-based tool that evaluates a business idea from multiple angles and perspectives, similar to how a VC would, by asking the user to score the business from different viewpoints. It produces two deliberately separate scores: how good the opportunity actually is and how good a fit it is for the user specifically. A planned next version will let one or more AIs answer the wizard so users can compare their evaluation with the AIs'.

vision-demos

This project provides open-source real-world computer vision demos focused on fitness, built on ViTPose+ Large pose estimation across different sports. The demos compare dancers performing the same choreography and compute a sync score, visualize a runner's ankle path and average knee shape upon foot strike, and count chin-up reps while measuring each rep's duration. Code is available on GitHub.

Conciliatower

A browser-based WASM remake of SimTower, produced through a six-month rewrite with Claude Code that replicates the original game's functionality from a Ghidra decompilation of the binary, an AI-generated summary of the original source code, and the author's memory of the gameplay. No new art was created: players load their own original game binary, which on-page code parses to pull out the original assets, preserving the original look and feel.

Total rewrite of long-shipping app
