Programming in C, C++, Java, Kotlin, Python and others. Creation of web and desktop applications.Programmer engineer with more than ten years of experience teaches programming classes at all levels.
My classes can help students of Computer Science Degrees or Cycles, new programmers or someone who is making their website or interacting with an Artificial Intelligence assistant.
- At the introductory level you will learn concepts such as variables, data types, flow control statements, functions, pointers, arrays, structures and search and sorting algorithms. This is what is normally taught in the "Programming Fundamentals" subject in the first year of a Bachelor's Degree in Computer Science or in other similar degrees.
- At the intermediate level you will learn more advanced concepts: classes, constructors, inheritance, polymorphism, interfaces, exceptions, access modifiers, collections and data structures.
- At the advanced level you will learn concepts of object-oriented programming, functional programming, database connections, HTTP protocols, creating web applications or how to deploy an application.
If you are already a programmer, you may want to take some refresher classes to reinforce certain concepts.

Graduate teacher gives courses in Physics & Chemistry, Mathematics, many years of experience.I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics.
I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since.
I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors.
I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...)
I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge.
I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence.
I can go to the student's home or also take the course via Skype.

Private coding / programming lessons with pythonPython 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.
