Projects

Angel Guirao — I build software for thinking clearly, deciding carefully, and shipping products people can actually use.

This page is a plain map of that work. Each piece is its own repository. I prefer to reuse good open-source tools and write the connecting tissue myself.

Public surfaces

These are the ones a stranger can open today:

Holzen	A practice for investors: pause when markets get loud, before moving capital
AI-Native Product Building	A living handbook on how AI changes product decisions
AIE Sessions	Open library of AI Engineer talks — catalogued and summarized so you can decide what to watch
angelguirao.com	Public site — interactive rooms and short footnotes from my reading

---

The rest of the stack

Most of this stays private. It exists so the public work has a spine.

Personal wiki (folio) — Notes from what I read and think. Capture, search, and turn ideas into short public footnotes when they’re ready.

Reading library (codex) — Books and PDFs on my machine, linked into the wiki.

Personal AI OS (PersonalOS / LifeOS) — A private distributed workspace: desks on Vercel, wakes on Trigger, life graphs on LangSmith, coding on Fly, ledger on Supabase — career, health, and venture work in one system, not a product for other people. Venture company text lives in Plane; PE/code in GitHub Issues; Postgres is the execution ledger. (architecture · trackers)

Experiment sandbox (bench) — A place to try open-source tools before adopting them for real.

Bitcoin node tooling (anchor) — Guides and setup for running my own Bitcoin infrastructure.

How it fits together

I read → notes land in the wiki → some ideas become public footnotes or handbook chapters → products that earn users (like Holzen) get their own home. The AI OS helps me run the private side. The sandbox is where experiments live or die before they graduate.
