Hey,
I’m Clément
Grennerat

Computer Science Student at INSA Lyon Bridging Code, Infrastructure, and Leadership

About me

Self-taught developer & CS Student with 6+ years of experience in software and system administration. Passionate about infrastructure and open-source – I create and maintain projects used by thousands. As Head of IT for my student union, I lead teams, deploy critical solutions, and adapt quickly to new challenges. Seeking a 2026 internship where I can leverage my technical depth and cross-functional skills to build robust systems or lead engineering projects.

Professional experience

From self-taught coding to formal studies, I’ve taken on leadership roles in student associations. Here are some highlights of my journey so far.
