Your website, your app, or whatever your business needs.

We build it. From the first version to having it live, with one person on the other side.

Contact

Tell me what has to ship.

I reply within one business day. If I cannot hit the date, I still say so. The message leaves from your mail app.

Work

Apps and websites already in production.

Fever app screen, showing plans and experiences in the city

App · 2015–2018

Fever

Leisure platform for finding things to do and buying tickets.

I joined as the only person on the app. Then I built the team, led it, and led the squad. The last stretch was deciding what stayed.

App and web · 2025

Alex

Legálitas’ legal assistant for everyday questions.

The Alex app and website: Legálitas answers legal questions in plain language, on the phone and in the browser.

Kado app showing digital business cards on two phones

App · 2021–2023

Kado

Digital business cards you share on the spot.

The app on iPhone and Android. UI, release, and one person.

Services

The website, the app, or both.

01

The app

For iPhone, Android, or both. From scratch, or from the one you already have.

  • What goes in the first version, in writing
  • We look at it together, not in a final reveal
  • Published, and the first week with users
02

The website

The storefront for your business, the shop, or the panel you run it from.

  • It can be the whole job, with no app
  • Or wired to the app when they share accounts or data
  • From the first page to having it live
03

Whatever it takes

Signup, payments, integrations, an internal panel. If your business needs it to work, it is part of the job.

  • If I can hit the date, I commit before I accept
  • Price and scope closed before we start. You pay for the delivery.
  • If it does not fit, I say so in the first conversation

How the work goes

One person on the other side, from start to release.

  1. 01

    You tell me the goal

    What the product has to achieve, for whom, and by when. That is enough for the first reply.

  2. 02

    Scope and price get closed

    I send back what is in, what is out, the risks and an order of magnitude. If I cannot hit the date, I say so there.

  3. 03

    You see the product evolve

    Short deliveries you can open. I do not vanish for months and come back with a surprise.

  4. 04

    It ships, and I stay for the start

    Stores, crashes and the first week with users. After that, a block of hours if you want one.

You can hand him a team and be calm about it: people will be coordinated and fine, and the project will ship.

Practice

It can be done. I have been doing it since 2010.

Telecommunications engineer, Universidad Carlos III.

Products with users since then: Fever, Wegow, GAME, Legálitas, Kado. The app, the website, or both in the same job.

If you already have something half-built, we continue it. If it has to start, it starts.
