A path with order and explanation, not a list of courses.
3 stages
Follow the official Introduction to C# series on Microsoft Learn, in Spanish and in order, without inventing a .NET bootcamp.
Who it is for: Beginners who want C# or the Microsoft ecosystem, not Python or the browser on day one.
Walk the path
3 stages
Start Excel in Spanish with a university course you can audit, then move to data and official Microsoft training, without selling the edX certificate as if it were free.
Who it is for: Anyone who needs spreadsheets for work and does not want a paid course on day one.
Walk the path
3 stages
Understand what AI is before training models, and only then move to practice that asks for Python.
Who it is for: Anyone who wants to get oriented in AI. If you do not program yet, do the Python path first; we do not skip that step.
Walk the path
3 stages
Learn JavaScript in Spanish: first contact with Cisco, algorithm practice on freeCodeCamp and a second stretch on NetAcad, without selling a third-party exam as if it were free.
Who it is for: Anyone who can already lay out a bit, or comes from the programming path, and wants the browser language with order.
Walk the path
3 stages
Start inbound in Spanish with HubSpot and then a broader view of digital marketing and Google Ads, with the conditions stated: you need an account and each platform issues its own certificate.
Who it is for: Anyone who wants digital marketing without paying a platform on day one.
Walk the path
3 stages
Go from never having programmed to understanding how software is built and publishing a page with HTML, CSS and a bit of JavaScript.
Who it is for: Anyone who does not know where to start and wants a real foundation, not a weekend tutorial.
Walk the path
3 stages
Learn Python with a first contact in Spanish, a serious foundation and project practice, without selling the Coursera certificate as if it were free.
Who it is for: Beginners who want Python for data, automation or a later move into AI.
Walk the path
3 stages
Start SQL in Spanish, practice with PostgreSQL and, if English works for you, close with Harvard’s course. Without selling a Coursera trial as if it were an audit.
Who it is for: Anyone who needs to query data or understands that back-end work asks for databases, not a first programming language.

Both can be a start. Doing them in parallel is the usual way to quit. This is how we choose, without inventing a hybrid.

You can start without code. You cannot skip the limit: to go further you will need Python. We say where that line is.

Audit is not “the course and the diploma are free”. We explain the difference so you do not pick a trial thinking it is free.

Do not start with a framework. First mark up a page, then style it, then add logic. That order is in the catalog.
Read guideFeatured because they are a good first step, not because they pay a commission.
The Microsoft Learn path we had is gone. Official Excel training in Spanish remains: videos and guides on the interface, formulas, formatting and pivot tables. It is free. It is not a university diploma.

View pageA short free path in Spanish: a first HTML page, CSS and a touch of accessibility, with VS Code in the browser. No prerequisites. It is not a bootcamp or a university certificate.

View pageHarvard’s introductory course to understand programming, algorithms and how software is built. It is demanding, in English, and still a solid starting point if you want a real foundation. If English is a barrier, there are Spanish options in the same cluster.
Harvard · Beginner · English
View pageThe CS50 version focused on Python. It starts from zero and covers functions, data, libraries and projects. Still in English. If you want a first contact in Spanish, start with Cisco or freeCodeCamp.
