Check out my new class on the C programming language!

65.28 C$ /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.
