Check out my new class on the C programming language!

47.61 $ /h

C is the most important programming language of the last 50 years. This course is aimed both at absolute beginners and at amateur programmers who wish to become proficient in C. I follow Kernighan and Ritchie's book but I elaborate on the fundamental concepts that underlie the development and runtime environments, e.g. how the compiler works, what the stack is, etc.

A computer science engineer with a Master's degree (Bac+5), specializing in programming and algorithms, I have been a private tutor since 2023. I support middle school, high school, and post-secondary students with a clear, supportive, and structured teaching approach. My goal is to strengthen logic, methodology, and confidence so that each student can make lasting progress and achieve their academic goals.

Passionate about teaching and sharing computer science knowledge, I also volunteer to help young people develop their logic, autonomy and digital skills in a caring and motivating environment.

I support high school and post-baccalaureate students according to their field of study:

- NSI (general high school): Python, algorithms, web basics (HTML, CSS, JavaScript) and databases (SQL)

- STI2D – SIN option: Python, PHP, C (Arduino), technical projects and embedded systems

- Vocational Baccalaureate (Digital Systems): networks, systems and applied programming

- BTS in Computer Science: structured and object-oriented programming, professional projects and tools

My approach is based on listening, patience, and teaching methods adapted to each individual's profile, in order to foster success, motivation, and a desire to learn.

Within cybersecurity, there are two branches that I deal with on a daily basis: defensive tasks to keep you cybersecure and offensive tasks to see how to detect vulnerabilities in different technologies.

Additionally, if you're looking at automations, we can address any questions or concerns to help you work on them correctly.

I am fully up-to-date with the latest tools, as my daily work requires me to stay current with new technical tactics and methodologies.

What we will work on:
• For Beginners: Fundamental rules, tactical vision, and essential opening principles.
• For Intermediate Players: Building a solid opening repertoire, middlegame planning, and tactical sharpness.
• For Advanced Players: Deep positional understanding, complex endgame techniques, and psychological preparation for tournaments.
• Game Analysis: In-depth review of your games to identify and eliminate recurring mistakes.

Lessons are conducted online via Zoom using interactive boards(Lichess/chess.com). Let’s unlock your full potential together!"

Artificial intelligence is revolutionary, but it can become a trap if used simply as an "answer generator." Parents, are you worried that your child will take the easy way out or lose their critical thinking skills? High school and university students, do you want to become more efficient while still taking pride in the originality of your work?

I will guide you in transforming AI into a true personal tutor. My goal: for the tool to serve your thinking, without ever replacing it.

What I wish to offer you (my methodology):

AI shouldn't write for you; it should help you think better. My approach focuses on:
- AI as a research partner: learning to "prompt" (query AI) to obtain relevant lines of thought and working structures.
- Critical thinking & ethics: Learn to verify sources, detect AI errors and ensure the academic honesty of your submissions.
- Methodological efficiency: Use the tool to synthesize dense courses, organize revisions or overcome writer's block.
- Student autonomy: Understanding how the tool works so as not to be dependent on it, but to become its pilot.

Specific examples of what we can accomplish together:

Dissertation/Thesis Methodology: Structure a coherent plan and identify key arguments without AI writing for you.

Exam preparation & Grand Oral: using AI to practice speaking, simulate examiner questions or simplify complex concepts (philosophy, economics, science).

Reading aid: learn to extract the essential information from a long or complex text to better understand it.

Organization: create personalized revision schedules and optimize your work time.
