I offer high-level support in computer science, algorithms, and programming, specifically designed for university students, engineering students, or adults retraining for new careers. My goal is to transform abstract coding concepts into logical, concrete solutions directly applicable to your academic projects and exams.

This teaching is based on a personalized pedagogy, which is precisely tailored to the specific needs of each student and the requirements of their curriculum.

Skills and areas of support:

• Languages & Tools: Proficiency in Python, Java, object-oriented programming (OOP) and databases (SQL).

• Algorithms & Logic: Design of algorithms, data structures and solving complex problems.

• Modern Methods & AI: Learning to intelligently use programming assistants and AI tools (like ChatGPT) to optimize workflow, understand errors, and code more efficiently.

• Practical support: Assistance with university projects, practical work (TP) and programming assignments.

A digital and interactive methodology:
The courses are conducted entirely online via an interactive platform. I make extensive use of modern tools such as screen sharing and real-time problem-solving with feedback, ensuring active learning and rapid assimilation of best development practices. The approach is practice-oriented to develop immediately applicable skills.

Formats of working sessions:

• Intensive format (60 minutes): Ideal for resolving a blocking bug, conducting a specific code review, or validating a precise algorithmic concept.

• In-depth format (90 minutes): Recommended for structuring a complex academic project, assimilating a new programming paradigm, or preparing for a technical exam.

Whether you are a beginner looking to understand the basics of code or an advanced student aiming for excellence in your programming projects, this tailored support will allow you to gain autonomy and performance.

Feel free to contact me to schedule your first session and structure your progress.

Do you want to learn how to program desktop applications in Java, C language, C ++, CSharp (C #), PSeint, Visual Basic .NET, Macros in Excel?

Do you want to learn how to program mobile applications in App Inventor 2?

My teaching methodology is Project Based Learning (PBL).

In this way, to build an application, I will teach you that the really important thing before sitting down to code (by attempt and error) in front of the computer, is the analysis and design of the algorithm (which constitutes 90% of the success of the program to be implemented. ), for this, with an example from the real world, the construction process will be explained: 1. Example with data from the real world, 2. Collection of information on requirements (input data, calculations, output data), 3. Hierarchy of operators (mathematical formulas versus computational formulas), 4. Desk test on a spreadsheet, 5. Constants, variables and data types to use, 6. Algorithm construction, 7. Flowchart, 8. Desk test on paper, 9. Implementation of the algorithm in the chosen programming language, if it is in console mode, it is implemented directly, if it is in form mode, the user interface is drawn on paper (UX) first.

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.
