What gets taken out
Removing the wholesale market from the product, simplifying the home page and carts, and adding the Bolsa as a mascot. A week of deciding what to leave out.
ReadBlog
What I am building with products, AI agents and data: the decisions, the costs and the lessons each attempt leaves behind.
A home-cooking recipe book
One hundred Peruvian home recipes with household measures — cups, spoonfuls, cloves of garlic — and a week that fills itself in with one tap.
ReadThe generic becomes a card
Someone who types "milk" isn't looking for a brand. Turning the generic into a card of its own, with hundreds of products that had to be separated without mixing what shouldn't mix.
ReadThe redesign lands
What I planned on paper was built screen by screen and went through a massive review. The hardest part was deciding what, out of everything, stayed out.
ReadA faster judge for the catalog
Judging whether two products are the same, case by case, doesn't scale. I brought in an outside service that clears the obvious cases on its own, saving the costly judgment for what disagrees.
ReadRethinking the interface from scratch
Before redesigning, I studied dozens of real apps to understand what actually works. Then came the hard part — deciding what of all that was Nada Menos.
ReadThe catalog opens up, and the list gets polished
Baby products, pet supplies, liquor and beauty join the catalog. Plus a batch of small shopping-list fixes — removing, undoing, where to add — that add up to feeling big.
ReadThe app becomes real
A real icon, signing in with Google from inside the app, and a scanner that answers "where's this cheaper" with the camera. Tested on an actual phone.
ReadThe app learns to measure without spying
Improving the product means knowing what people use and what they don't. Building that measurement without storing what someone typed or who they are.
ReadThe price depends on who is asking
Some stores charge differently depending on the card or membership you use. Ignoring that meant the "cheapest" price we showed wasn't always the real one.
ReadReorganizing the house before it grows
The front-end code had grown fast and tangled. Before building the app, every piece got its own name, its own boundary, and its own test.
ReadWhat the instrument doesn't look at
If the product is going to say every day where things are cheaper, it had better be right. I spent this week measuring how often it isn't.
ReadThe brand learns to speak
Nada Menos starts telling people every day what got cheaper, with a synthetic presenter of its own. Generating the video was the easy part.
ReadThe catalog audits itself
Duplicate product cards kept slipping through. The discipline of measuring every fix before calling it good, taken one step further.
ReadMi semana: from list to full menu
The question missing from the picture came before the shopping list — what to cook. Mi semana is a weekly planner built for whoever plans a family's meals.
ReadOperating live
The bugs that only show up once real people use the product every day. And the rule I adopted so none of them slip by unnoticed again.
ReadLanding in the cloud
Everything built so far had lived on a laptop. The story of the first real deployment, and the surprises that only show up once real traffic arrives.
ReadA face of its own
Nada Menos adopts Curaca's design system. The quipu, the knotted-cord instrument, becomes the central metaphor for the spending chart.
ReadMaking comparison actually save money
Driving to three stores to save fifty cents isn't saving, it's a hassle. How I thought through splitting a long shopping list across several stores.
ReadThe real problem: recognizing the same product
Four supermarkets, each with its own way of naming and packaging the same item. The story of Nada Menos's hardest problem, and a catalog that broke once.
ReadKeeping lists from getting lost
A shopping list that only lives in the browser disappears the day you switch phones. Moving from a demo to something people can actually rely on.
ReadThe comparator is born
The first version of Nada Menos already had to solve something far from trivial — the same product goes by a different name at every supermarket.
ReadWhy does Curaca exist?
Twenty years selling technology, and now I build it with a team of AI agents. Why I am leaving a commercial role to code again.
