State Engineer, former student of the *classes préparatoires* MPSI/MP*, and currently pursuing a Master’s degree in Fundamental Mathematics, I have always been passionate about the beauty and rigor of mathematics. I am deeply committed to sharing this passion with my students through a clear, engaging, and stimulating approach. All my students have successfully passed their exams, thanks to a method that combines deep understanding with the joy of reasoning. This course is intended for those who wish to go beyond formulas, to understand the why behind the how, and to discover mathematics as an art of thinking. Together, we will explore analysis, algebra, and geometry, developing intuition, rigor, and mathematical creativity.
