Multi-site infrastructure

A selection of my professional infrastructure work, presented through scale, decisions and responsibility.

Case 01 · Networks

Restructuring connectivity across eight locations.

I planned and designed the complete transition of the enterprise network across eight locations from HP Enterprise to Huawei Enterprise, and led its implementation from architecture and segmentation through configuration, deployment and production rollout. Today, I administer and continue to evolve the resulting LAN/WAN infrastructure, including enterprise Wi-Fi, Check Point security and remote-access services.

Segmentation

VLANs, trunks, subnetting, SSIDs and Wi-Fi authentication profiles.

Perimeter

Firewall and NAT rules, VPN access and network-security policies.

Operations

Remote management, technical documentation and national and local intervention planning.

Case 02 · Systems

Building a more operable systems and platform foundation.

Implementation and administration of Windows and Linux services, Microsoft identity, virtualization, private cloud and internal applications.

Identity

Microsoft 365, Entra ID, Active Directory, groups, permissions and licensing.

Compute

Proxmox VE, Hyper-V, Ubuntu/Debian servers and Docker applications.

Visibility

Ticketing, wiki, monitoring, dashboards, insights and digital signage.

Working principles

Technology only matters when operations improve.

Reduce ambiguity through segmentation and clear standards
Document for continuity, not merely delivery
Balance security, availability and supportability
Connect technical decisions to budget, procurement and evolution
