What's included

  • Users with roles and permissions (everyone sees only what they should).
  • Reports and dashboards with up-to-date information.
  • Import of your current Excel files, so you don't start from scratch.
  • Works from any browser, including on your phone.
  • Written user guides for each type of user.

How I work

  1. You tell me what you need.

    A free first conversation, in writing over WhatsApp or email. You only pay once you approve the project.

  2. I show you the solution before writing any code.

    You get a written proposal with the scope, timeline and price, plus a mockup so you can see how it will look. What's in the proposal is what gets delivered.

  3. I build it and hand it over.

    Every week you see a version you can test. At the end you get the code, the database, the access credentials, the documentation and a user guide.

I work with English-speaking clients in writing — WhatsApp, email and proposals. Calls and meetings are in Spanish.

Commitments

No made-up testimonials. Commitments in writing.

These four points go into the contract for every project.

  • You talk to the person who writes the code.

    No salespeople or middlemen getting what you need lost in translation.

  • You see progress every week.

    A version you can actually test, not just a status report.

  • The code is yours.

    At the end you get the code, the database, the access credentials and the documentation.

  • A warranty after delivery.

    30 days for websites and 90 for systems: I fix any bug in what we agreed on, at no cost. New changes go into a maintenance plan or a separate quote.

Frequently asked questions

Can I keep using my Excel files?

Yes. The systems can read your current files. In the Sales dashboard, the supervisor uploads their Excel file in whatever format they already use, and the system adapts to it.

Does it work on phones?

Yes, from any browser. In the Sales dashboard, each sales advisor checks their own metrics on their phone.

How much does it cost?

It depends on the scope. After our first conversation, I send you a proposal with a fixed price.
