This course aims to engage learners with little or no programming experience to create Java programs. Participants are introduced to object-oriented programming concepts, terminology and syntax, and the steps required to create basic Java programs using the Alice and Eclipse interactive development environments. Hand-on practice enables learners to experience the power of computer programming.

The JavaTM programming language can be challenging for computer programmers with limited or no experience in object-oriented programming. To provide an easy introduction to Java, Alice is explored first in this course, so that fundamental principles and skills are established using 3D animations in a fun, visually rich environment.

When learners become familiar with the concepts of object-oriented programming, they can proceed with the Eclipse integrated development environment (IDE), which is widely used in computer programming. It contains a basic workspace and an extendable plug-in system for customising the environment.

The content and pace of the course is adapted to the age and needs of the learners.

Python is the programming language these days. It is simple, nice and almost all modern applications use it. With Python, we can now create artificial intelligence models that reduce human effort and give us more accurate and reliable results. The Java and C languages are not lacking in importance, they also make it possible to create applications optimized in terms of RAM.

The composition of the course depends on the level of the student and his own objectives. The first session is a one-hour evaluation session which allows the diagnosis of the level and the needs of the student. From this diagnosis we establish together a program that we will follow during our course.

Generally the course allows the student to assimilate:
* Predefined Data Types & Variables;
* Conditional Structures & Loops;
* Functions ;
* Object-oriented programming (OOP);
* Digital engineering;
* An introduction to databases (Examples and uses)
* Relational Algebra
* LDD, LCD, LMD, LCT
* SQL queries (SELECT, UPDATE, ...)
* Creation of a database and automation of queries using the Python language
* Handling files (TXT, Excel, CSV, JSON, Word);
* Data science;
* Introduction and some applications of Artificial Intelligence.

I am waiting for you to start this adventure.

Java is an essential object-oriented programming language in the world of software development. This foundational course will guide you through the key concepts of Java, starting with basic syntax and control structures (loops, conditionals). You will then discover the principles of object-oriented programming: classes, objects, inheritance, polymorphism, and encapsulation. The course also covers exception handling, Java collections (ArrayList, HashMap), and interfaces. Through practical exercises and real-world projects, you will learn how to write clean and maintainable code. Special attention will be paid to good development practices and Java naming conventions. By the end of the course, you will be able to design and develop simple yet functional Java applications, laying the foundation for more advanced development.

Python programming language course, both theoretical and practical, explained in Arabic and English from scratch. We'll understand what library, if condition, for loop, class, arrays, print, and more are, so we can build a complete project. And, as a cybersecurity professional, I'll also teach him how to exploit several vulnerabilities in Python using a script.

This class is designed for students, young adults, or professionals who want to better understand computer science and programming, whether they are beginners or already have some experience.

I focus on helping students understand concepts deeply, not just memorize syntax. Topics can include programming fundamentals, algorithms, problem-solving, debugging, and practical projects using languages such as Python, JavaScript, HTML/CSS or SQL, depending on your goals.

My teaching approach is structured, progressive and adapted to each student’s level. I take the time to explain complex ideas in a clear and concrete way, using real-life examples and hands-on exercises.

Lessons can be oriented toward:
- discovering programming from scratch
- strengthening academic knowledge
- preparing exams or technical interviews
- supporting career change or personal projects

Between sessions, I may suggest small exercises or mini-projects to help consolidate what we’ve learned, always at a pace that keeps students motivated, not overwhelmed.
