I am a Full-stack Software Developer with 20 years of experience working on a variety of projects, from small-scale initiatives to large, complex systems.
Since 2017, I have focused on developing a general-purpose low-code application builder framework while mentoring and assessing students in Front-end, Full-stack, and web development programs at OpenClassrooms, where I also serve as a jury member evaluating students for their diplomas. I have conducted over 3,000 mentoring sessions, contributing significantly to the academic and professional success of my mentees.
What I enjoy most about mentoring is guiding individuals through their learning journey, helping them not only acquire technical skills but also build confidence and develop strong problem-solving abilities. My approach involves setting clear objectives and working on practical projects to ensure steady progress. By focusing on mastering the fundamentals of programming—HTML, CSS, and JavaScript—and fostering active learning, I aim to support both personal and professional growth.
