About Karim

As a network expert with over 10 years of professional experience, I have successfully worked for numerous operators, manufacturers, and large national and international clients, including CAC40 companies.

Throughout my career, I have developed in-depth expertise in level 3 network and Wi-Fi support, redesigning LAN and WAN network architectures, as well as major network transformation and migration projects towards new technologies such as DMVPN and SD-WAN.

I am passionate about my work and committed to providing my clients with innovative and effective network solutions that meet their specific needs. Thanks to my technical expertise and extensive market experience, I am proactive and capable of delivering a quality solution that enables my clients to achieve their goals.

I am available for one-off assignments or longer-term collaborations, and I am confident that I can bring added value to your company. Contact me to discuss your network needs and see how I can help you achieve your technical objectives.

My assignments are mostly carried out remotely, but I do perform on-site missions depending on the nature and conditions after discussion.
