What I believe in

Four principles that explain every decision at Logali Tech.

01

Clean core as a discipline, not a slogan

Extending S/4HANA without mortgaging the upgrade. RAP, BTP and extensibility properly understood: what I teach is the same thing I defend on projects.

02

Training in Spanish on par with English

Quality SAP technical material almost always arrives in English, late or never. Logali Tech exists so that in Spanish nobody has to settle for less.

03

Truly senior, not a factory

In consulting it is me who steps in, not a profit and loss account. Few projects at a time, with the same standard I teach in the courses.

04

Knowledge is meant to be shared

The Labs MCPs are public, the blog has no fluff, and I am the creator and sponsor of open-hand.org: the profit from the books is donated in full. As simple as that.

Now

What I am working on this quarter, updated with every launch.

  • Building Logali Tech: the subscription-based SAP training platform, with 25 courses and monthly live classes for Premium.
  • Writing the Logali Books collection: ABAP Objects, CDS Views, RAP and S/4HANA extensibility.
  • Selective BTP consulting with client teams (architecture, RAP, integration).
  • At Labs: MCPs that connect AI assistants with ABAP systems, published for free.
The road to here

  1. 2004

    First ABAP projects

    Hands-on development in R/3 environments: reports, exits, forms. The classic school.

  2. 2008

    ABAP Objects for real

    OOP stops being optional on projects. No material in Spanish: you learn through sheer practice.

  3. 2013

    International projects

    Industry, banking, retail and public sector. Distributed teams and ever larger architectures.

  4. 2015

    The Logali brand is born

    I founded Logali Europe, the first company of the brand. From it would come the school, the books and everything that followed.

  5. 2016

    The HANA era

    Migrations to S/4HANA, CDS Views and the paradigm shift in the data model.

  6. 2020

    Cloud and extensibility

    BTP, RAP, Clean Core. The stack that defines the next decade of the ecosystem.

  7. 2024

    Training at scale

    The Logali school passes 100,000 students across Udemy and logalitech.com. Teaching stops being a side project.

  8. 2026

    Logali Tech

    The subscription platform: courses, Logali Books, BTP consulting and Labs. Built by engineers, for professionals.

What I write about

ABAP Cloud, CDS, RAP, Clean Core and what I see on projects. Technical notes with no marketing, published on the blog.
