Scratch is a visual programming language created by MIT and oriented to facilitate its learning intuitively through blocks. And this means? That instead of writing code we will have different pieces as if it were a puzzle and we will fit them to develop the different orders until we have our project, which could be perfectly a video game.

Learning Scratch the student will develop and improve his critical thinking and understanding, his creativity, and facilitate his systemic thinking. All this will help you improve your school performance.

I help children with their homework, as well as helping them study the subjects that cost them the most.
I believe that education must be close and children must be encouraged to learn and motivated in order to achieve their goals and be eager for learning.

Hello! You will surely think that learning to use many computer programs or mobile applications is impossible and many of those who ask you for help do not have patience with you. I can guide and teach you how to use the internet, WhatsApp and get around the computer faster and easier. Additionally, if you want to write documents, do accounts on electronic spreadsheets or make presentations with interactions of your photos and trips, I can help you. I am passionate about you learning and if that requires patience and understanding, then we do it, I will help you.

Programming for Kids is a course targeted for kids aged 8-16 who want to explore the world of computer programming and learn in a fun, visual way. Suitable for both complete beginners and kids who have some prior knowledge from school.
The course can be taught with either Python, C#, or C++, depending on the kid's needs. The topics, projects and homework will be similar regardless of the programming language chosen, and they will be tailored to the kid's age and level. To keep the process engaging for the kid, there will be fun, visual projects like creating a simple game, and all fundamental concepts will be taught in that context. The general structure of the course is as follows:

--- Part 1: Programming Fundamentals

1. What is programming?
2. Variables
3. if, else
4. Arrays
5. /// Exercise / Project
6. Loops: for, while
7. Strings
8. Functions
9. /// Exercise / Project

--- Part 2: Object-Oriented Programming (OOP)

1. Class, Object
2. /// Exercise / Project
3. Methods, Members, public/private, Constructor/Destructor
4. /// Exercise / Project
5. Inheritance
6. Abstract class, Interface, Polymorphism
7. /// Exercise / Project

I offer private computer and programming classes from basic to intermediate-high level, including the possibility of learning programming from scratch, without the need for previous knowledge. My specialties include:

✔ Python – From fundamentals to advanced development and automation.
✔ Web development – HTML, CSS, JavaScript, modern frameworks.
✔ Mobile programming – Android and iOS applications.
✔ Databases and SQL – Design, optimization and advanced queries.
✔ Good practices and methodologies – Agile development, design patterns and software architecture.

I am a professional with more than 8 years of experience in software development, having worked both in Spain and abroad, including experience at CERN. I have a Higher Degree in Multiplatform Application Development, a degree in Software Engineering and a Master's Degree in Big Data.

Classes can be taught in Spanish or English and can be held online, at my home, or I can travel to the student's location and preference. My approach is practical, combining theory with real exercises to ensure a better understanding and application of knowledge.

Programming enables machines designed and built using robotics to successfully perform the tasks for which they were designed. Robotics is a branch of mechanical, electrical, electronic, and computer engineering. All these disciplines deal with the design, construction, operation, and support of robots, machines, artifacts, or devices that perform the activities, tasks, or jobs performed by humans.

This class is a high-impact, results-focused program designed for students preparing for the Cambridge IGCSE Information and Communication Technology and/or the Computer Science examinations.

The core objective is to maximise your grade potential by mastering both the theoretical concepts and the specific practical skills required by the Cambridge exam structure.

🌟 Why Choose This Class?
Examining Body Expert: I have extensive experience working with the Cambridge International examining body, having taught and assessed this exact syllabus in international schools for at least seven years.

Mark Scheme Insights: You will receive coaching that goes beyond the textbook. Learn how to deconstruct command words, structure your answers to meet mark scheme criteria, and understand the subtle differences between the exam papers.

Practical Skills Specialization: We focus heavily on the common software applications and problem-solving scenarios (Spreadsheets, Databases, Web Authoring, etc.) that frequently appear in the practical exam for IGCSE Information and Communication Technology.
