Deadlog
A changelog archive for the video game Deadlock, used as a test project for the Mog markup language; per-change classifications such as buffs and nerfs are stored as Mog attributes directly alongside the change text.
CurveFit
This web app is a weightlifting SPA that explores the pareto frontier of a lifter's strength across weight and rep count, and gathers data to understand how fatigue works. It is rep-based, with bar speed measurement in development (currently by strapping a phone to the wrist, with plans for an iOS app supporting the Apple Watch).
Jelly
This iOS camera app rolls the shutter and scores each picture as it comes in, telling the photographer when they have a good one where everybody's eyes are open and everyone is smiling.
Bowerjack
This invite-only web app uses AI to create custom subject playing cards on any theme: users drop in their own art or have their AI agent research creative commons/public domain art that is allowed to be printed, then download print sheets to cut locally on a Cricut or order from online playing card vendors. Planned expansion covers other paper goods with many individual elements such as 12-month and 365-day calendars, field guides, affirmation cards, and tarot cards. Development focuses on token efficiency, documented in a whitepaper comparing token, time, and cost efficiency of different approaches.
AI fork co-maintenance platform
This planned platform lets people maintaining software forks have their AI agents automatically share the ongoing work of review, CI, and rebasing on upstream, with trust established and reputation tracked so that it is difficult for bad actors to inject malware into a fork.
fless.io
This service turns apartment hunting into a lean-back experience by skipping the spreadsheets, endless emails, scheduling work, and spammy building follow-ups, while connecting users with vetted buildings, movers, and other moving-related services. It launched in Chicago, New York, and Santa Clara with more cities added regularly; users can request a city via a form to be notified when it goes live, and can point AI agents to its ai-agents page to have the agent handle the search.
Custom Music Visualizer
A custom music visualizer application that gives the creator more control over the final rendered results than existing visualizer tools, built to produce visuals that complement the builder's electronic/ambient songs. A first proof-of-concept render was produced with it, and a second, more complex rendering-engine showcase was in the works.
LoomDSP
A free and open source modular audio composition environment, inspired by Eurorack modular, VCV Rack, and Bitwig Studio's The Grid. Accepts ideas and bug reports.
ReadPlusOne
A Spanish learning app that uses LLMs to generate stories tailored to the reader's specific vocabulary level. While reading, users tap words they don't know to add them to a spaced repetition system (SRS), and the SRS is later used to generate stories that review those words in context rather than as plain flash cards. A native iOS app built in Swift is in development.
Asheron's Call 1999 client server emulator
A server emulator that works with the original 1999 Asheron's Call game client, as well as the beta and preview clients. Built by reverse-engineering the launch-era network communication layer (which differs greatly from the end-of-retail 2015 client other emulators target), then restoring the abandoned or changed launch-era game mechanics and reconstructing the game world's original content and quests, using documented details from the game's running era together with tooling and Claude-assisted pattern matching.
Koaches
This app is an interview coaching and preparation platform that helps candidates prepare for behavioral interviews. It includes story creation, mock interview practice, and interview-specific practice, starting with behavioral interviews before expanding to other interview types.

Hand-plane hardwood slab furniture project
A hands-on woodworking project that uses hand planes to flatten a hardwood slab (and dimensional lumber) milled from a tree felled in the yard, undertaken as an analog escape from AI/digital overload, with the goal of building furniture.

Studio Galois
A line of math, science, and CS-inspired jewelry whose pieces are beautiful but carry hidden scientific meaning. Two styles so far: lambda calculus based pieces (a y-combinator earring and an expression that computes Graham's number) and quantum computing circuit pieces, sold online with lengthy science explanations of what each design represents.

MimicScribe
An on-device speech transcriber built on a custom-trained Parakeet Ultra model.
