À propos

Introduction

In 2011, I graduated with a BAC+5 in Network Engineering after 5 years of work-study. Then, I had the opportunity to work for many major market players (Veolia, Sodexo, OBS, Manpower, etc.) To respond to current IT challenges, I developed in-demand skills in network engineering (CCNP) and project management (PRINCE2).
