Every floor came from somewhere.
Journey
Hitchhiking across Europe, bus routes through Argentina, seasons waiting tables — and, since 2020, building software. Each line is a real route.

What I carry.
Everything I carry
One bag, opened. Travel taught me what to keep close; building taught me what to leave out.

Method
- 01
Start from the operation: watch the real workflow before modelling it.
- 02
Make the domain explicit: types, invariants, and boundaries enforced in code and database.
- 03
Automate with guardrails: agents get narrow tools, deterministic routing and gates.
- 04
Ship in vertical slices, verified in a real browser and by tests.
04 The Mind
The next floor is yours.
