What I Do

Two audiences. Four services. One practice.

Three services help enterprise organisations govern and scale their architecture. One helps technology vendors win in enterprise sales. All four draw on the same director-level architecture practice.

For enterprise organisations
01 / 04

ARB as a Service

A fully operational Architecture Review Board, chaired by a director-level architect, running inside your organisation on a fractional basis, from first session to board-level reporting. Active from week three.

ARB Chair Design Authority Standards Ownership Executive Reporting Regulatory Alignment

Ideal for organisations of 50–600 people that need governed architecture decision-making without the lead time of a full-time Head of Architecture. The complete governance framework is deployed and running in two weeks.

For technology vendors

ArchWin

Pre-sales architecture for Series A–C AI, analytics, and data platform vendors running active enterprise sales. CTO-credible proposals, RFP co-authorship, and reference architectures delivered in 48 hours.

RFP Co-Author Architecture Review Reference Architecture 48hr Turnaround

Ideal for vendors losing enterprise deals in the final 20%, but on architecture credibility. Closes that gap without the lead time of building an in-house pre-sales architecture capability.

Cloud & AI Platform Strategy

Define and deliver enterprise cloud architecture across AWS and Azure—from multi-cloud strategy and AI/ML platform design to migration planning, FinOps governance, and observability frameworks that scale with your organisation.

AWS / Azure AI/ML Architecture Kubernetes FinOps Observability

Ideal for organisations embarking on cloud migration, adopting AI platforms, or struggling with cloud efficiency. Bring proven patterns from large-scale enterprise deployments directly into your environment—without building the expertise from scratch.

How It Works

From first conversation to lasting impact

A structured, low-friction process designed to get you moving quickly—with the right governance in place from day one.

1

Discovery & Diagnosis

We begin with a focused 60-minute session to understand your current architecture, team capability, regulatory obligations, and strategic goals. This is tailored to your context.

2

Strategic Architecture Assessment

I map your current state against best-in-class standards and deliver a prioritised action plan—covering governance gaps, risk exposure, platform opportunities, and quick wins.

3

Engagement & Delivery

We agree the engagement model that fits—retainer, project, or advisory and begin delivering measurable architectural outcomes with clear accountability at every stage.

4

Review & Evolve

Regular governance reviews ensure the architecture continues to serve changing business needs. Your organisation grows stronger with every decision made.

About

Director-calibre architecture, available to you

I'm Peter Muirhead—an enterprise technology architecture leader with over a decade of experience shaping cloud and AI platform strategy across some of Europe's most complex, highly regulated environments.

I've chaired Architecture Review Boards governing 150–200 design authority reviews annually, delivered multi-million-dollar enterprise architecture across AWS, Azure and Kubernetes, and provided executive-level design authority to global governments and major enterprise clients.

My approach bridges two worlds: the technical depth to hold authoritative positions on cloud-native, AI/ML and observability architecture, and the commercial acumen to connect infrastructure decisions directly to revenue, margin and customer outcomes.

I've built and scaled technical organisations from the ground up, navigated Europe's most demanding regulatory frameworks with zero material compliance failures, and served as executive escalation authority for C-Suite and Board-level stakeholders.

Now I bring that experience to ambitious organisations on a fractional basis—providing the strategic vision, governance rigour and leadership presence that defines lasting competitive advantage.
