Observation as craft, evidence as product
A public studio for AI systems, field notes, and proof.
I build AI and product systems, write in public, and use photography as a way to keep attention honest. The site now treats older work as provenance and newer work as present-tense judgment.
- Reviewable AI and product-discovery workflows
- Essays, notes, and build logs with evidence trails
- Photography and experiments as observation practice
Selected photograph
New York, MarilagFeatured writing
Essays that stay close to evidence.
Longer pieces about product discovery, AI systems, and what becomes visible when observation is treated as a craft.
Field Notes for Product Discovery
Good product discovery depends less on louder frameworks than on better observation loops.
Photo story
Images with editorial weight.
Photography is a first-class medium here, not portfolio filler.
New York, Marilag
A short sequence about weather, movement, and the editorial density of the city.
Selected work
Technical work with a clearer point of view.
A small number of case studies that explain why the work mattered, not only what shipped.
TradingAgents Packet Flow
Clarifying a research-to-decision workflow by turning analysis into a durable packet boundary.
Experiments and lineage
The live site keeps both the current portfolio and the old evidence trail.
The public estate is managed directly in this GitHub Pages repo, while archive and game routes remain visible static exceptions.
Latest notes
Notebook-scale observations.
Shorter dispatches on systems, cities, fieldwork, and the habits of public thinking.
Photography is a form of debugging
A frame makes you decide what matters, what is noise, and where the edge of the system really is.
Observation should leave evidence
A note on why product intuition becomes more useful when it stays attached to its source.
Cities sharpen product taste
Dense urban environments are full of clues about pacing, friction, signage, and human tolerance.
Editorial systems reduce friction
The best publishing systems lower the activation energy between noticing something and making it public.
