Raúl Mazo & Gabriel Camargo. Engineering Modern Web Applications with Next.js: Full-Stack Architecture with Modern Patterns and Engineering Principles for React Developers. Amazon KDP, ISBN: 979-8195699079, France, 11/05/2026.

Building a web app has never been easier. Building a good one has never been harder. This book focuses on what tools can’t automate: engineering judgment, architectural thinking, and deep understanding.

This book goes beyond frameworks and syntax. It teaches you how to:

- Make sound architectural decisions from day one.
- Prevent simple applications from turning into unmaintainable systems
- Apply SOLID principles effectively in React and Next.js environments
- Structure complex applications using proven patterns like MVC, MVP, MVVM, and MVT
- Build with clear separation of concerns between client and server
- Design systems that remain testable, flexible, and scalable over time.

Raúl Mazo & Gabriel Camargo. Mastering Web Architecture with Laravel: Professional Development with Modern Engineering Principles and Patterns. Amazon Press, ISBN: 9798243156394, France, 2026.

 Through progressive mastery, you'll internalize SOLID principles within the Laravel ecosystem, distinguish between MVC, MVP, MVVM, and MVT patterns through practical comparative analysis, and leverage Laravel’s service container and dependency injection to architect loosely-coupled systems. The book guides you through building a complete Book Exchange application, demonstrating how to structure Blade views strategically, implement controllers that remain thin and focused, design Eloquent models that encapsulate business logic elegantly, and decouple layers to enable independent evolution of each concern.

So, who is this book for?

This book is essential for PHP developers transitioning from tutorial-driven learning to professional practice; Computer Science students and educators seeking rigorous engineering approaches for modern PHP development 

Raúl Mazo & Gabriel Camargo. Modern Web Engineering with Spring Boot: How to Build Robust Java-based Web Applications Using Engineering Principles and Architectural Patterns. Amazon Press, ISBN: 979-8272549853, France, 2025.  

By the end of this book, you will have acquired both theoretical depth and practical skills to build production-ready Java applications. You’ll master SOLID principles and web-specific guidelines, understand and apply architectural patterns (MVC, MVP, MVVM, MVT) through comparative analysis, and leverage Inversion of Control to create maintainable systems. Each chapter includes hands-on exercises with a full-stack Book Exchange application that evolves throughout the text, allowing you to translate concepts into production-grade code immediately.

This book is designed for undergraduate and graduate students in Computer Science and Software Engineering; educators and researchers exploring practical application of engineering principles; and professional Java developers, software architects, and technical leads building the next generation of robust, performant, and evolutive web applications with Spring Boot

Raúl Mazo. Inteligencia Artificial Simbólica: De la Lógica al Razonamiento Automatizado. Amazon Press, ISBN: 9798276198446, France, 2025.

Este libro ofrece una base completa sobre la inteligencia artificial simbólica, tendiendo un puente entre la lógica clásica y las técnicas de razonamiento automatizado modernas. El libro va más allá del razonamiento deductivo para abarcar la programación lógica inductiva (ILP) probabilística, que permite representar sistemas capaces de aprender reglas y probabilidades a partir de la evidencia, y el razonamiento abductivo, que permite a los sistemas explicar, verificar e incluso exhibir inteligencia creativa. Su utilidad práctica se demuestra a través de una amplia colección de ejemplos académicos, científicos y de ingeniería, en disciplinas tales como la ciberseguridad, defensa, gestión de proyectos, robótica, ingeniería de software, líneas de productos, psicología y epistemología. Y los ejemplos explicados en el libro son tan variados como las disciplinas, y van desde los simples sistemas de gestión de reuniones y proyectos en SAT y CSP, pasando por los sistemas de control de robots y dispositivos de riego, la representación y la inferencia de teorías científicas, la verificación de modelos de software, el diagnóstico de enfermedades y de problemas de ciberseguridad, el aprendizaje automático en sistemas de ensamblado y manufactura flexibles usando solvers neuro-simbólicos, los sistemas de defensa antiaérea tales como el domo de hierro, y hasta agentes de ML que pueden aprender de sus propios errores gracias a mecanismos de meta-aprendizaje en  el solver ASP Clingo; y muchos más...

Raúl Mazo & Gabriel Camargo, Sustainable Web Development, Amazon press, ISBN: 979-8327610835, France, 2024. 

In an era where digital experiences shape our daily lives, the responsibility of creating sustainable web applications has never been more crucial. This book is essential for modern and engaged engineers who seek to understand the impact of their work on the environment and strive to develop applications that are not only efficient but also eco-friendly. 

In this book, you will gain a deep understanding of the evolution of web development, from static to dynamic websites, and dissect the anatomy of dynamic requests and exchanges between browsers and web servers. The book covers essential topics such as HTML5 for sustainable web application development, CSS for building responsive and aesthetically pleasing websites, and JavaScript for implementing different programming paradigms with a sustainable approach. Additionally, you will learn how TypeScript's static typing can enhance the reliability of your applications and how to leverage React's component-based architecture to create efficient, resource-saving user interfaces.

Furthermore, practical exercises and questions will help you practice and test what you have learned throughout each chapter.

Mazo Raúl. Guía para la adopción industrial de líneas de productos de software. Editorial Eafit, ISBN 978-958-720-506-0, Colombia, 2018

The essential concepts of product line engineering, the necessary knowledge, and the models and the methods used for developing product lines are progressively introduced in this guide in a straightforward approach: through a complete and unified framework.

There exist other works in the literature that have helped in part and that have contributed in issues specific to product line development. These works are written mostly in English (no one in Spanish) and are the result of research on a specific topic within product line engineering. To unify the concepts and terms that express them, at the beginning of the guide we present (i) a reading guide that shows and explains the different ways of reading the book, (ii) a unified glossary for product line engineering, whose terms are used throughout the book, and (iii) a base example corresponding to a real line of virtual stores that will help us explain and demonstrate the solutions provided in each of the chapters of the guide.
