Python is one of the best, if not the best, language to start learning programming. It is also one of the most widely used languages today, especially in cutting-edge areas such as machine learning.

This popularity means that Python is constantly evolving. It offers a wide range of tools and libraries, which are free and very varied.

As an aeronautical engineer, I like to share my knowledge and derive satisfaction from it by teaching and motivating others.

I'm used to working with people of different ages. I believe in the importance of segmenting learning, visualizing progress, setting concrete goals and practicing regularly.

Beyond these general principles, there is no magic rule or method. Some approaches work with some students but not with others. Adaptation to individual needs is therefore the main objective of private lessons. So I will do my best to find what motivates and helps my student.

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.

Are you a university student, engineer, or professional who needs to actually use data — not just learn theory about it?
This course is built around real problems and real code. We skip the textbook formulas and go straight to applying statistics and data science the way professionals do: with Python (pandas, NumPy, scikit-learn, matplotlib) and R (RStudio).
What we cover, adapted to your level and goals:
- Descriptive and inferential statistics (the ones that actually matter)
- Data cleaning, exploration, and visualization
- Regression, classification, and intro to machine learning
- Time series and forecasting basics
- R for statistical analysis and academic research

Who this is for:
- University students in statistics, economics, engineering, or biology
- Professionals wanting to move into data analysis or data science
- Researchers who need to process and present data properly

I use Python and R professionally as a working engineer — everything I teach comes from real application, not just academic exercises.
