Enterprise Network Operations & Engineering

Maintaining the network's reliability, not just its existence.

My portfolio reflects an operational engineering mindset: designing and maintaining dynamic network environments, resolving complex faults, supporting critical services and continuously improving the platforms that organisations rely upon.

01 · Reliability

Operational engineering built around service continuity

My approach to network engineering is centred on dependable service delivery. I combine proactive support, first- and second-line troubleshooting, incident resolution and ongoing maintenance to keep network services operational and aligned with organisational requirements.

02 · NOC Operations

Technical leadership within a fast-paced NOC

As a Technical Enterprise NOC Shift Manager, I apply shift and resource management alongside stakeholder liaison and client requirement analysis. This supports effective transition of technical resources, clear operational priorities and consistent delivery in a demanding network operations environment.

03 · Network Engineering

Enterprise routing, switching and resilient connectivity

My engineering background spans LAN, WAN and WLAN environments, with practical experience across Cisco, Meraki, Alcatel and SD-WAN. I also work across Ethernet, SoGea, FTTC, ADSL and cellular connectivity, with routing knowledge covering BGP, OSPF, ECMP and MPLS.

04 · Platforms

Vendor platforms, security and enterprise tooling

My experience includes Cisco Nexus, ISE, Prime and vManager, alongside Alcatel NTU and FortiManager/FortiGate. Security and connectivity responsibilities also include Fortinet, CrowdSec, OPNSense, VPN solutions and network monitoring, supported by CA Spectrum, ServiceNow and Remedy.

05 · Cloud & Automation

Cloud connectivity and infrastructure automation

I have supported cloud infrastructure including Amazon EC2 and Direct Connect, while developing capability across vManage and Ansible. Combined with strong Linux knowledge, these tools provide a foundation for repeatable, efficient and scalable network operations.

06 · Infrastructure

Virtualisation, containers and modern infrastructure

Beyond core networking, I work across VMware, Proxmox, TrueNAS-SCALE, Docker and Kubernetes, with experience across Debian, Ubuntu and OpenSUSE. This broader infrastructure perspective supports practical solutions that connect networking, compute, security and service delivery.

Professional objective

Reliable infrastructure should enable the business, not become the business's problem.

I am seeking opportunities where enterprise network engineering, operational discipline and continuous improvement can be combined to strengthen service resilience, improve operational efficiency and support evolving network environments.

Open source mindset

Build. Host. Learn. Improve.

Open-source and self-hosted technologies provide a practical space to explore Linux, virtualisation, containers and infrastructure platforms while continually developing scalable and efficient solutions.
