- No New Debt (Claude Skill) — A Claude Code skill that installs a ratcheted quality methodology into TypeScript repos: existing debt is counted into a committed baseline that can only shrink, never grandfathered away.
- Open Fountain — A fast, open-data map of public drinking fountains and refill points. Free, clean water should be easy to find, for everyone — no paywalls, no accounts.
- GitHub CI debugger / viewer — A Deno CLI + MCP server that turns GitHub Actions runs into step-by-step timing tables with deltas against the last green run, so performance regressions are obvious at a glance.
- Unreal Engine Crawling framework — A spline-based locomotion system for UE5 that lets characters traverse custom crawling routes with full animation and interaction control — 100% Blueprints, no C++ required.
- Agent Config Manager — A CLI that ports AI agent configurations (skills, tools, rules, instructions) between GitHub Copilot, Cursor, Claude and Windsurf, with validation, backups and dry-run previews.
- More will be disclosed soon!

Diverse Tech Experience:
I've shipped production software across virtually every domain in tech—from hardcore backend systems and server implementations to immersive experiences (AR/VR/XR), native mobile applications, video game development, and everything in between. Whether it's architecting scalable cloud services (AWS/GCP), building performant web applications, crafting interactive 3D experiences, or developing mobile solutions, I thrive at the intersection of creative innovation and solid engineering.
