Selected work

Three examples of design work across enterprise networking, security and communications.

Financial services

Multi-site SD-WAN and proof-of-concept plan

I designed a multi-site architecture around application performance, resilience, security and operational requirements. The proof-of-concept plan defined failover scenarios and review checkpoints.

Manufacturing

Plant IT and OT network design

I designed resilient connectivity and segmentation for plant environments with separate IT and OT requirements. The design documented trust boundaries, dependencies and availability requirements.

Oil and gas

Unified communications target architecture

I designed the target architecture for voice infrastructure, call routing and contact-centre integration, including dependencies, interfaces and design risks.

How I work

  1. 01

    Understand

    Confirm the problem, requirements, constraints, owners and success criteria.

  2. 02

    Assess

    Compare options, dependencies, trade-offs and technical risks.

  3. 03

    Design

    Define the architecture, security controls, resilience and integration points.

  4. 04

    Document

    Record decisions, assumptions, diagrams, validation criteria and recommendations.

AI-assisted practice

I use AI-assisted research and drafting where useful, verify primary sources, and remain responsible for every technical decision.

Architecture scope

My current scope is architecture and design across three technical areas.

Enterprise networks

Campus, wireless, WAN and SD-WAN, data centre and cloud connectivity.

Security architecture

Secure edge, segmentation, trust boundaries and availability requirements.
