À propos de Marwen

I hold an Engineering degree from the Royal Military Academy in Brussels (graduated December 2009), with extensive experience as a Network Engineer working in international environments. Over the years, I’ve built strong expertise in network support, design, configuration, and deployment across complex on-premises and cloud architectures.

I have deep hands-on experience with Amazon Web Services (AWS) and Microsoft Azure, including:
• Infrastructure as Code (IaC)
• Transit Gateway, CWAN, Direct Connect, ExpressRoute
• VPC/VNet design
• Load Balancers, NVAs, and high-availability architectures

My background also includes a broad understanding of IP networks, Layer 2/3 technologies, virtualization, and network consolidation. I’ve worked with a range of modern networking technologies such as SD-WAN, MPLS, firewalls, and hybrid cloud infrastructures.

I’m constantly learning — currently pursuing Cisco CCIE (R&S) and AWS Advanced Networking Specialty certifications — and I value clear communication, teamwork, and continuous improvement.
