Websites, stores, dashboards, MVPs and apps.

Websites, stores, dashboards, MVPs and apps.

I design and build them myself, from the idea until they’re up and running, for small businesses, founders and agencies.

Automations

What you do by hand every day, happening on its own.

  • Data that loads itself
  • AI that reads photos and fills in the data
  1. An order comes in
  2. It goes into the spreadsheet
  3. The confirmation email goes out
  4. The warehouse gets notified
  5. Stock gets updated

MVP

The first version of your idea, working and in the hands of real users.

  • A prototype you can use before going all in
  • A web or app version ready to test
  • AI integration when it adds something

  • “Are you being overcharged?” It estimates an electrical installation and checks the electrician’s quote against it.

ServiceIn. In front, the published app; behind it, the redesigned day closing, still in testing. With test data.

Every layer, one person.

A website or an app is built in layers: the interface you touch, the API that responds, the data that gets stored and the server it runs on. I do all of them. Pick a layer and I’ll show you what I build it with.

prototype

Before I quote, I build.

Rompiente. A surf shop that rearranges itself around the water temperature, with a wetsuit advisor.

For one proposal I had the store working before anything was signed.

From the idea to up and running.

One person on the other side, from start to finish. This is how every project moves forward.

  1. You tell me what you need

    By email or message. An idea in one sentence is enough to get started.

  2. I show you a prototype that works

    Before going all in, you see and try what you’re getting, not a PDF full of promises.

  3. I build it

    You talk directly to me, the one writing the code. No middlemen.

  4. I launch it

    Domain, hosting, database, App Store and Google Play: it’s left up and running.

  5. I stick around

    Adjustments and improvements as the business grows or changes.

Tell me what you need.

What you need

You’ll hear back from me, the one who’s going to build it.

Or email me directly
