Questions before booking

First, a 15-minute video call to get to know each other: you tell me your goal and your level, and I suggest a plan. Then we start the classes: online and live, with a shared screen and editor, at your own pace. You can book the appointment with a date or ask me to contact you without a date.

Yes: if you let me know at least 24 hours in advance, rescheduling is free. With less than 24 hours' notice, the session counts as held (except in cases of force majeure).

A computer and an internet connection. Classes are via video call with a shared editor (I send you the link upon confirmation). For AI topics we use free cloud tools, without installing anything.

All classes are online and live, by video call with a shared screen and editor. They are in Spanish; if you need another language, just ask. Schedule: Monday to Friday 12:00–20:00 and weekends 10:00–13:00 (Madrid time).

No, and we make it clear: classes are about accompanying you. I explain the material, guide you as you code, and review your code so YOU can complete your assignments, projects, and exams. I don't do your work for you or covertly solve exams.

In a group the price is per person and drops with size: 2 people 32 €/h and 3 people 28 €/h. The intensive is a three-hour block for 105 €: useful the day before an exam, to start a thesis or to unblock a stalled project.

Continuity and price. If you are a student, real progress comes week by week: a pack organizes study and prepares for exams without cramming, and works out up to 15% cheaper. If you are a professional, a pack is a scheduled itinerary (from zero to mastering the tool in weeks) with predictable investment and an upfront discount.

From the «Reserva» (Booking) section on this page: choose a slot for the free appointment (at least 24 hours in advance) or ask me to contact you without a date. I confirm by email within 24 hours.

Programming (C, Java, Python), algorithms and data structures, distributed systems, advanced databases (MongoDB, Redis, Neo4j), information retrieval and analysis, machine and deep learning, NLP and LLMs, MLOps, probability and calculus. If you are unsure about your specific case, we will go through it in the appointment.

Bank transfer, Bizum or PayPal. The method is agreed in the appointment and payment is made before the first session (or before the first month of mentoring or when you buy the pack).

Yes, I issue an invoice. I work as an independent professional.

Yes. We work on vibe coding with judgement: you drive, the assistant writes and we review together what it produces. We cover how to ask well, how to read the code the AI returns, when to use it and when not to, and how to leave it tested and maintainable. It works whether you are starting out or already code and want to benefit without filling the project with code you do not understand.
