We had the opportunity to work with Kamel on two occasions in recent months regarding data processing, consolidation, and visualization of our data. He successfully assisted us in creating automated dashboards that now allow us to closely monitor our KPIs. Kamel is very professional. Pedagogical and attentive, he was able to translate our precise expectations and needs into real solutions despite the numerous internal constraints we had. He works quickly and is available. We will not hesitate to call on him again for similar projects. Thank you, Kamel!
