If you’ve ever felt that science and math are difficult, it’s probably because no one showed you how to think like a problem solver.
In my classes, you’ll learn not just formulas or code but how to truly understand concepts, apply them, and build strong logical intuition.

I teach:
• 🔢 Mathematics: From algebra and calculus to applied problem-solving for real-world use.
• 💻 Computer Science: Coding fundamentals (Python, C++), algorithms, and logical thinking for beginners and intermediate learners.
• ⚛️ Physics: Mechanics, thermodynamics, and practical examples that make abstract ideas simple and visual.

As a Software Engineer and Master’s student in Engineering at Nagoya University, I bring both academic knowledge and hands-on experience from real projects. My teaching approach is interactive, visual, and deeply focused on understanding over memorization.

Let’s turn complex problems into clear, step-by-step insights — and make learning something you genuinely enjoy.

As an experienced teacher of mathematics, physics and programming, I offer online courses tailored to students wishing to improve their understanding, prepare for their exams or succeed in their university projects.

I have been teaching for several years to students of different levels: high school, university, engineering schools, and adults retraining for a new career. My goal is to make complex concepts simpler through clear, progressive explanations adapted to each student's level.

I can assist you in the following areas in particular:

• Mathematics: analysis, algebra, probability, statistics, differential calculus, exercises and exam preparation
• Physics: mechanics, electricity, thermodynamics, general physics and problem solving
• Computer science and programming: Python, Java, algorithms, object-oriented programming, SQL, project support and practical exercises

The courses are conducted online via videoconference with screen sharing and detailed step-by-step explanations. I place great importance on a genuine understanding of the concepts and on student autonomy.

I also use modern artificial intelligence tools (such as ChatGPT and programming assistants) to help students learn more effectively, while developing their thinking skills and personal understanding.

I can help you for:
• Exam and competition preparation
• regular support
• university projects
• homework and practical exercises
• catch-up and remedial education
• Introduction to programming

Feel free to contact me to discuss your goals and level in order to set up support tailored to your needs.

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.

I offer programming lessons for students who want to build strong foundations, improve their problem-solving skills, or get help with coursework and projects.

I am a Master’s student in HealthTech and Robotics in Strasbourg, with a strong background in engineering, mathematics, programming, and technical problem solving. I teach in a clear, patient, and structured way, with a focus on helping students understand the logic behind the code, not just copy solutions.

Depending on the student’s level and needs, I can help with programming fundamentals, algorithms, problem solving, debugging, and writing cleaner code. I mainly teach Python, MATLAB, C, and C++, and I can also help students understand basic embedded programming concepts and microcontroller-related work.

My goal is to make programming more understandable, less intimidating, and more practical, while helping each student build confidence and become more independent.

Vous souhaitez découvrir l'univers de la programmation mais vous ne savez pas par où commencer ? Python est le langage idéal : simple à lire, puissant et utilisé partout (Web, Intelligence Artificielle, Automatisation).

Ce cours s'adresse aux débutants complets, aux étudiants ou aux passionnés qui souhaitent acquérir des bases solides sans se perdre dans une théorie trop complexe. Mon objectif est de vous rendre autonome rapidement.

Au programme :
Le contenu est adapté selon votre rythme, mais suit généralement cette progression :

Installation & Setup : Configurer votre environnement de travail (VS Code, PyCharm ou IDLE).

Les Fondamentaux : Variables, types de données (nombres, listes, dictionnaires) et opérations de base.

La Logique de Programmation : Maîtriser les conditions (if/else) et les boucles (for/while) pour donner de l'intelligence à votre code.

Fonctions & Modularité : Apprendre à structurer son code pour qu'il soit propre et réutilisable.

Ma Méthodologie
80% de Pratique : On apprend mieux en tapant du code qu'en regardant des diapositives.

Pédagogie Positive : Pas de jugement, on avance étape par étape. Chaque erreur est une occasion d'apprendre.

Suivi Personnalisé : Je m'adapte à vos objectifs spécifiques (aide aux devoirs, projet personnel ou curiosité intellectuelle).
