OFFENSIVE OPERATIONS
PHILOSOPHY

I am a freelance pentester passionate about offensive security and reverse engineering. Trained at École 42, I forged my technical skills through intensive hands-on practice and peer-to-peer learning.

My approach to cybersecurity is rooted in knowledge sharing: I firmly believe that collaborating and documenting our findings is how we grow together. That is the very purpose of this portfolio and my write-ups. In the field, I focus heavily on low-level languages like C and Assembly.
