Saber Karoui



Saber Karoui, I was born on July 6, 1978, I did my primary and secondary studies in Tunis. After my baccalaureate I was sent by the Tunisian State to study at the Royal Military School in Brussels, which was a very enriching human experience for me where I learned a sense of responsibility. Then I continued my university studies in the Faculty of Engineering in Mons to carry out the studies and the job that I always wanted to be.
Once I had my degree in Electrical Civil Engineering, I subsequently joined M-Link Teleport, currently called WIS, where I learned various technologies for more than 17 years in which I went through several challenges for the execution and management of several complex projects.

Electrical Civil Engineer & Web Developer.

My passion for football has meant that I have been a referee of Belgian Federation since more 18 years.


Having more than 17 years of experience in telecom and in the troubleshooting of different issues starting with satellite transmission through the TDM to the VOIP, I have acquired a solid background to find the optimal solution to each new problem. The analysis of CDRs for the calculation of KPIs is an achievement during all these years and which also allows troubleshooting to give an explanation and for the resolution of some issues. This experience subsequently allowed me to develop very specialized applications to provide solutions that allow fraud management, facilitate implementations of interconnections between operators, routing management and finding solutions to very specific problems.

I use my skills for the management of complex projects. For me, the success of each project can be summed up in its good initial study and the good understanding of the objectives to be achieved. Once this has been defined in a clear way, the next step is to develop the intelligent process for the execution of the project and to define a schedule for each task to be executed. The integration of new technologies and artificial intelligence are essential for the acceleration of the goals to be achieved. Then the analysis of KPIs and continuous monitoring of progress will be the keys to the success of the project.

Project study and initiation

In this phase, the idea for the project will be studied with all the relevant parties in order to define the main lines to follow for its realization

Scheduling tasks

Prepare the schedule for the realization of each point and share the tasks between the involved team's members

KPIs Analysis

A good analysis of the KPIs will make it possible to make the necessary corrections where necessary and to achieve the desired objective

Goals to reach

List all the points to be achieved and think about the best way to proceed to meet all the objectives

New Technologies and Artificial Intelligence

Whenever possible, do not hesitate to use artificial intelligence to solve each objective that turns out to be complex

Continuous progress monitoring

Obviously, permanent monitoring of the progress of the project allows both to validate the objectives already achieved and to give an indication of its success
