Delivery leadership
for complex, regulated change.

I lead programme planning and PMO functions across defence, national infrastructure, technology and automotive, from competitive bids and transformation delivery to off-track recovery.

01 What I do

Three kinds of brief.

Transformation

A transformation to lead. I turn strategic intent into governed delivery, with clear ownership, visible dependencies and timely decisions.

PMO

A PMO to establish or lead. I create the controls, reporting and decision rhythm leaders need to act.

Planning

A programme plan to build or assure. I build an integrated plan that surfaces risks, clashes and dependencies early - and that sponsors and delivery teams can use and trust.

02 The record

The controls behind
won bids and recovered programmes.

I build and run the controls that complex programmes depend on: integrated plans, dependency and critical-path management, and reporting that sponsors can act on. On the winning Ministry of Defence bid, my tooling linked MS Project to client-facing Plan-on-a-Page graphics, so the team could test scenarios and re-plan live in negotiation. Security clearance is sponsor-held, re-activatable on engagement.

Planning and PMO leadership, with practical automation.

Lead Planner, Lead PMO, AI Systems Architect. I build AI tools that extract and distil milestones, activities and decision points, and the automation that has replaced whole manual reporting cycles. When a programme is in trouble, I am usually the one asked to steady it.
