About Lahoucine

I am a cross-functional and versatile IT engineer, passionate about solving complex problems and supporting companies in their digital transformation. At 41 years old and with over 15 years of experience, I have developed solid expertise in various environments, ranging from business telephony to virtualization, including networks, security, and automation.

My career has allowed me to evolve in contact with demanding IT departments, in contexts where service continuity, security, and performance are at the heart of concerns. I have thus supported CIOs in modernizing their infrastructure, migrating their telephony systems, and automating critical processes to gain efficiency.

What sets me apart is my versatility: I can work on a complex telephony migration project (Avaya Aura to Avaya Cloud Office, setting up Teams telephony with Direct Routing, integrating Cisco videoconferencing), as well as on systems and networks projects (VMware deployment, Veeam backup, MPLS architecture, IPsec/SSL VPN), or even on automation missions (.NET, PowerShell, UiPath, Power Automate).

Beyond the technical aspect, I have always placed great importance on listening to needs and on pedagogy. A project is only successful if users adopt the implemented solution: that's why I prioritize clear documentation, skills transfer, and personalized support.

Today, as an independent consultant, I put this know-how at the service of companies looking for a reliable partner, capable of taking charge of a project from end to end or providing expert support on specific topics.
