Back to original languageAbout Sébastien
With 7 years of freelance experience and a degree in computer engineering from Cesi d’Aix en Provence, I have completed numerous projects in various languages during my freelance and training years. I learned the basics in C, C++, PHP, JS, HTML, CSS, and during my internships, I improved my skills in Python, Java, C#, and SQL. I am also proficient in VBA. Through personal, academic, and professional projects on neural networks, I have learned and mastered techniques related to machine learning and deep learning for computer vision and NLP challenges.
I master the concepts of MVC, MVVM, microservices for architecture, object-oriented programming, machine learning, deep learning, and AI agents.
