About Sébastien

I help IT and telephony service companies that lack internal resources to offer 3CX IP telephony or Centrex solutions to their clients.

I realized that many companies specializing in these areas need '3CX' skills to implement this solution for their clients.
But the scarcity of this type of skill is a barrier to their recruitment.

Having worked fully in this field as an employee for several years, managing over a hundred clients, I decided to go freelance to help you with pre-sales, deployment, monitoring, and user training for the 3CX solution, for which I am certified as an 'Expert'.

This allows you to avoid the burden of an internal recruitment that might fail, while delegating with complete confidence.
You can then focus on the commercial aspect with the relief of external support.
