Academic support in Python and SQL

From 41.26 $ /h

I offer academic support in Python and SQL programming, aimed at secondary and higher-education students as well as individuals transitioning into data-related, IT roles or those who follow AI-focused courses.

I work in the field of AI and data science, combining both theoretical foundations and practical applications. Having learned Python and SQL almost exclusively on my own, I am well aware of the blockers that learners face, whether it be programming logic, debugging, code structure and so on.

Lessons are fully tailored to your needs:
• learning Python or SQL fundamentals
• assistance with assignments, projects, or coursework
• exam preparation
• improving best practices and problem-solving skills
• help throughout your training sessions.

The focus is on deep understanding, autonomy, and developing a structured analytical mindset, rather than mindless learning.

The time spent on lesson preparation and any necessary research is fully included in the proposed rate. I can travel to the student’s home for an additional fee.

About Me

I am a data scientist working in the fields of data science, artificial intelligence, and decision-support system optimization. I use Python and SQL on a daily basis, with the goal of best addressing my clients’ needs and expectations.

My background combines academic research in economics and statistics with hands-on experience in forecasting, inventory, and optimization systems. This dual approach allows me to explain not only how to write code, but more importantly why it should be written in a particular way.

Learning to program is not just about writing code. It's about learning to analyze a problem, construct a line of reasoning, and develop effective solutions.

For over 35 years, I have been supporting university students, engineering school students and adults retraining in learning computer science and programming.

Whether you are a beginner or preparing for an exam, a university project or a technical interview, I adapt to your level and your objectives.

Subjects taught
Python
Java
SQL and databases
Algorithmic
Data structures
Object-oriented programming (OOP)
Program design and debugging
What we work on together
Understanding fundamental concepts rather than memorizing code.
Develop a problem-solving method.
Correct and improve your programs.
Prepare for practical work, projects and exams.
Acquire good programming practices used in higher education and in business.
A pedagogy based on practice

Each session alternates between explanations, demonstrations, and exercises. We write, test, and debug the code together so that you understand not only how to program, but more importantly, why a solution works.

When it's helpful, I also show you how to use programming assistance tools thoughtfully, including AI-powered assistants. The goal isn't to let AI program for you, but to teach you how to verify, understand, and improve the solutions it provides.

Session Procedure

60-minute session

Ideal for solving a specific problem, understanding a difficult concept, or correcting a program.

90-minute session

Recommended for a university project, a complete refresher course or exam preparation.

My commitment

My goal is for you to gradually become independent. At the end of each session, you should be able to understand your code, explain your choices, and continue your work with greater confidence.

I will be happy to support you in your progress, whatever your starting level.

Maths and statistics can be scary but they are undoubtedly extremely important. Unfortunately, students often feel overwhelmed with technical terminology and formulas that apparently are of no use. My goal is to demystify mathematics and statistics, making them closer to your daily life and/or area of expertise. Discipline, accessibility, and (why not?) a bit of fun are key factors to an effective and long-lasting learning process!

MIT App Inventor is a visual programming environment that enables everyone to build apps for smartphones and tablets.

The course for beginners does not require any previous programming experience. It starts with an introduction to the App Inventor interface. Then, after Event-Driven Programming is explained, learners will discover the available command blocks which they will have to combine to make their own apps. During this course, learners will have the opportunity to use their imagination and practise analytical and critical thinking to create their own apps such as animations, games, quizzes, tourist guides or drawing apps.

This course also aims to engage intermediate or even advanced App Inventor programmers who can build on their previous experience to create more sophisticated apps.

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

Two types of courses are possible:

(1) On the one hand, support courses for the elderly. How to facilitate his access to his emails? How to configure your computer hardware? How to create a simple and robust IT environment over time.
(2) On the other hand, I teach programming to people who would like to discover this field. I can teach several programming languages, but Python is probably the one I recommend to start with.

Thanks to the Zoom software, possibility for me to unlock your computer problems remotely in case of emergency!

My accompaniment:

• Available H24, 7/7, via message/email outside of class to answer urgent questions, or to solve an unforeseen computer problem.
• Provide additional exercises if necessary.
• Possibility of giving lessons to two students at the same time if they are in the same class.

Python is both the most intuitive computer language but also one of the most current: suitable for artificial intelligence, digital methods, web development, etc. Once mastered, create scripts helping to Everyday life becomes child's play. Mastering python is a very good skill to put on a CV.

Thanks to its large and loyal community, python has a large number of different libraries, facilitating the exploration of the breadth of fields related to computing: video games, websites, artificial intelligence, physical simulation, mathematical oddities, etc. .

I myself have a degree in civil computer engineering and it is a field that fascinates me.
I have already given several computer science and mathematics courses. I was also a computer science tutor for engineering bachelor students when I was a student myself. Teaching in a good mood is something I love!
