Programming is FUN! [Python - Programming fundamentals - Game Programming - OOP - Javascript - Algorithms]
My lessons are ideally for complete beginners to programming within the age range of 8-16. Programming can be a very creative and fun skill to learn. I focus on providing a solid understanding of the core programming concepts so that we can apply what we learn creatively to make interesting programs. I have my own content that covers fundamental computing concepts in an accessible way and I'm am working on more. I would be happy to provide general tutoring for Python or Javascript to help with revision or exams. I think the best and easiest way to learn a skill is to ensure that you enjoy doing it. This way of thinking guides how I tutor. Together, lets learn to code.

Private coding / programming lessons with python
Python 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.
