Research is where I start.
Building is how I learn what I missed.

Twelve years designing. Eight in research. Now solo-building AI-native products where the design is what makes the AI honest.

Urban Tech AI

Piná 🍍

AI for urban-code compliance. Reads a building project, cross-references it against municipal code, tells the architect if the design will pass, before city hall says no.

  • 4-level extraction pipeline (PDF-first, vision on gaps)
  • Source-tagged claims, every value points back to PDF / CALC / LEI

Pre-investment terrain viability. Multi-scenario reports for investors deciding whether to buy or develop a plot, investor language, minutes not weeks.

  • City rules parameterized via JSON, new municipalities onboard fast

Qualfita

AI music-taste mapper for people whose Spotify algorithm has flattened them. Reads your library, reveals the shape of your taste.

  • "Side A to begin. Side B to discover.", two modes
  • Visual identity in active iteration (cassette/VHS language)

Approach (04)

What holds across projects
P / 01

Trust-centric by default

AI that shows its work and asks when it doesn't know. Source tags over confidence theater. The product doesn't replace the expert, it gives them an auditable triage.

P / 02

Atomic Research as method

Qualitative findings as atomic, queryable units. Same logic from Sheets-by-hand to LLM agents. Method is what compounds, tools are throughput.

P / 03

Methods over tools

Tools change every year. Methods compound for decades. I bet on the practices I'll still be using in five.

P / 04

Constraints as signal

What a project leaves on the table tells you more than what it ships. The messy middle is a senior move, not a junior risk.
