I build focused, browser-first tools for AI workflows, simulation, planning, and decision support.
Start here:
- Project portfolio - curated launchpad for active flagships and stable utilities.
- Sponsor this work - support continued maintenance and new public tools.
- Maintainer handoff - public-safe continuation notes for future AI maintainers.
| Project | What it does | Open |
|---|---|---|
| ModelTab | No-install BYOK AI chat PWA for OpenAI-compatible endpoints, Gemini keys, and local provider workflows. | App |
| nFIRE | Deterministic financial independence and solvency planner for local-first retirement modeling. | App |
| FIFA-WC-Sim | Offline-capable World Cup 2026 simulator with Monte Carlo projections and transparent data health. | App |
| LocalFirstApps | Consolidated suite of privacy-first browser apps for dashboards, quizzes, reflection, decisions, fitness, and facilitation. | Apps |
Stable utility apps are maintained inside LocalFirstApps instead of promoted as separate standalone surfaces.
- Keep tools simple enough to run from GitHub Pages when possible.
- Prefer local-first, privacy-conscious workflows where a backend is not needed.
- Keep maintenance focused on the few projects that are most useful.
- Make assumptions, data, and limitations visible instead of hiding them.
