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.

With years of experience as an engineer in Belgium and the Netherlands, I would like to help other students navigate the sometimes complex world of mathematics and physics. During my studies, I tutored for six years in secondary schools in the regions of The Hague, Delft, Rotterdam, and Antwerp. In doing so, I aim to review the subject matter interactively with the student and link theoretical concepts as much as possible to examples from our daily lives to prepare and motivate the student.

So if you would like tutoring on one or more subjects in mathematics or physics, you can contact me.

Does your child understand mathematics, but their results don't reflect their effort?

He gets average grades despite his hard work?
He understands the lesson but loses points in the exercises?
Is he lacking in method, precision, or confidence?
Does he want to move to a higher level and achieve better results?

I can help him identify what is causing him to lose points and to implement a more effective work method.

I am a mathematics teacher with 15 years of teaching experience and hold a Master's degree in mathematics. I tutor middle and high school students, particularly in the French and Moroccan curricula.

🎯 UNDERSTANDING WHY GRADES ARE NOT IMPROVING

Two students with the same grade can have completely different difficulties.

One may lack basic knowledge.
The other person may understand the lesson but not know how to solve the exercises.
Another person may have the necessary knowledge but lose many points due to errors in calculation, reasoning, or writing.

That is why I begin by identifying the difficulties that are actually limiting the student's progress.

📈 HOW TO IMPROVE RESULTS?

We are working specifically on:

• a thorough understanding of the course;
• mastery of fundamental concepts;
• the solution method;
• the analysis of the statements;
• mathematical reasoning;
• calculation and logic errors;
• drafting the solutions;
• exercises of progressive difficulty;
• time management during checks;
• autonomy in the face of exercises.

The goal is not to do dozens of exercises without a method.

We seek to understand the errors, correct bad habits and gradually build effective automatic processes.

🧠 A METHOD TO BECOME MORE INDEPENDENT

During the sessions, I am not simply trying to provide the solution.

I guide the student so that they gradually learn to:

Understand → Analyze → Choose a method → Solve → Verify

This approach allows the student to better manage exercises when working alone.

The goal is for him to need less and less help over time.

📚 FOR STUDENTS WHO WANT TO IMPROVE

This support can be particularly useful for a student who:

• wants to improve his grades;
• wants to consolidate his knowledge;
• aims for better results in controls;
• wants to get ahead of the program;
• prepares for an important year;
• wants to gradually prepare for the Brevet or the Baccalaureate;
• understands the concepts but lacks effectiveness in exercises.

I adapt the exercises and the pace of work to the actual level of each student.

💻 INTERACTIVE ONLINE COURSES

The classes are held remotely using Google Meet and an interactive whiteboard.

The student actively participates throughout the session: he searches, answers questions, completes exercises and explains his reasoning.

I can also send screenshots of the work done during the session so that the student can review the important concepts after the lesson.

🏆 15 YEARS OF EXPERIENCE

With 15 years of experience in teaching mathematics, I have supported students with very different levels, objectives and difficulties.

For my final year students who were tutored in mathematics, I achieved a 100% success rate in the Baccalaureate, with 75% obtaining a distinction of "Bien" or "Très Bien".

My goal is to use this experience to provide personalized and practical support.

👨‍🎓 LEVELS

• College
• 5th
• 4th
• 3rd
• High school
• Second
• First
• Final year
• French and Moroccan programs

📩 DO YOU WANT YOUR CHILD TO PROGRESS?

In your message, simply tell me:

• its level;
• his current average in mathematics;
• the difficulties he encounters;
• its objective.

This will allow me to better understand his situation and determine the points to work on as a priority.

My goal is simple: to help the student better understand mathematics, correct their mistakes, improve their methods and make lasting progress.

► EXPERT STATISTICS, DATA ANALYTICS, MACHINE LEARNING & AI TUTOR FROM SWITZERLAND
► UNIVERSITY, FOUNDATION, IB, A-LEVEL & INTERNATIONAL SCHOOL SUPPORT

I completed my Master’s degree in Business Information Systems at a Swiss University of Applied Sciences, where my academic background strongly combined mathematics, statistics, data analysis, analytical thinking and problem-solving. This technical and data-oriented foundation shaped the way I teach today: clearly, logically and with a strong focus on real understanding.

For many years, I have successfully supported students in Statistics, Data Analytics, Machine Learning and AI. My main focus is especially on Statistics — from basic descriptive statistics to advanced statistical methods, hypothesis testing, regression, probability distributions and interpretation of results.

I mainly use R for statistical analysis, data handling, visualisation and practical exercises. My goal is not only to help students calculate results, but to make sure they understand what the results mean and how to explain them correctly.

► STATISTICS, DATA ANALYTICS & AI SUPPORT

► STATISTICS & PROBABILITY
I help students understand descriptive statistics, probability, random variables, distributions, sampling, confidence intervals, hypothesis testing, p-values, correlation, regression and statistical interpretation. My lessons focus on explaining the logic behind each method, not just applying formulas.

► APPLIED STATISTICS WITH R
I support students in using R for statistical analysis, data cleaning, visualisation, hypothesis testing, regression models and interpretation of outputs. Students learn how to connect theory, calculation, code and real meaning step by step.

► QUANTITATIVE METHODS & RESEARCH STATISTICS
I help students with statistical methods used in business, economics, psychology, social sciences, science and university research. This includes choosing the correct test, understanding assumptions, interpreting results and presenting findings clearly.

► DATA ANALYTICS & DATA SCIENCE
I support students with data preparation, exploratory data analysis, visualisation, dashboards, summary statistics and practical interpretation. The focus is always on understanding the data and drawing meaningful conclusions.

► MACHINE LEARNING & AI FOUNDATIONS
For students working with modern data topics, I also provide support in the foundations of Machine Learning and AI, including regression, classification, clustering, model evaluation and practical applications. These topics are explained from a statistical point of view, so students understand the logic behind the models.

► UNIVERSITY, FOUNDATION & INTERNATIONAL COURSES
I support students in Statistics, Data Analytics, Business Analytics, Quantitative Methods, Econometrics, Research Methods and technical modules. I help with exam preparation, assignments, projects and practical data analysis tasks.

► HOW I TEACH

► I FOCUS ON REAL STATISTICAL UNDERSTANDING.
Statistics becomes much easier when students understand why a method is used, what the result means and how to interpret it correctly.

► I EXPLAIN FORMULAS STEP BY STEP.
Difficult formulas, tests and models are broken down into simple, logical parts so students can follow the reasoning clearly.

► I CONNECT THEORY WITH R PRACTICE.
Students learn not only the statistical theory, but also how to apply it in R, read the output and explain the result in proper academic language.

► I HELP STUDENTS CHOOSE THE RIGHT METHOD.
Many students struggle with deciding whether to use a t-test, chi-square test, ANOVA, regression or another method. I teach students how to recognise the correct approach from the question or dataset.

► I TRAIN INTERPRETATION AND EXAM TECHNIQUE.
Students learn how to structure statistical answers, write clear conclusions, explain p-values, interpret confidence intervals and present results professionally.

► I ADAPT EVERY LESSON TO THE STUDENT.
Some students need help with theory, others with R coding, assignments, research projects or exam preparation. I adjust every lesson to the student’s exact course, level and goals.

► YEARS OF EXPERIENCE WITH STATISTICS, DATA & UNIVERSITY STUDENTS

Over the years, I have successfully supported students from demanding academic programmes, helping them strengthen their statistical understanding, improve their analytical thinking and achieve excellent progress in Statistics, Data Analytics, Machine Learning and AI.

► ONLINE LESSONS

► Interactive whiteboard
► Clear digital notes
► Step-by-step statistical explanations
► R support for data analysis
► Exam preparation
► Assignment and project guidance
► Practical examples with real datasets
► Focused one-to-one support from Switzerland

► MY GOAL

My goal is not only to help students pass exams or complete assignments, but to help them truly understand Statistics. With the right guidance, statistical methods become logical, practical and much easier to apply.

► SUBJECTS: Statistics, Probability, Data Analytics, Data Science, Machine Learning, AI, Quantitative Methods, Research Methods, Econometrics
► MAIN TOOL: R
► LEVELS: International School, IB, A-Level, Foundation Courses, University Modules, Professional Training

B- PERSONALIZED TUTORING: LEARNING HOW TO REASON
Machine learning and artificial intelligence become much more accessible when mathematics, algorithms, Python code, data, and real-world applications are clearly connected.

My lessons help you move beyond simply copying code or using models as “black boxes.” You will learn how to define the problem correctly, prepare the data, select an appropriate algorithm, understand how it works, train and evaluate the model, diagnose errors, improve performance, and interpret results rigorously and responsibly.

Each lesson is personalized according to your current level, mathematical background, programming experience, dataset, university work, research project, interview preparation, or professional objective. We begin by identifying your existing knowledge, software environment, expected outcomes, and main conceptual or technical difficulties. We then establish a structured learning plan.

The first lesson combines a discussion of your background, objectives, and tutoring needs; an initial assessment of your current knowledge; personalized planning and organization of future sessions; and a short trial lesson to determine the most effective learning approach.

A typical session may include conceptual explanation, development of mathematical intuition, live coding, guided implementation, model evaluation, technical problem solving, and a concise summary of the next steps.

You may work with your own dataset, university assignment, research project, or professional problem, provided that confidential information is handled appropriately. I can also provide structured examples and datasets suited to your level.

My goal is not simply to help you run an algorithm. It is to help you understand why it is appropriate, how it learns from data, how to evaluate it correctly, why it may fail, and how to build a reliable, interpretable, and scientifically rigorous solution.
