01 / SERVICES
A portfolio nobody can see clearly. A programme losing confidence. An estate with unknown dependencies. An AI investment without a clear purpose. Six connected services bring technical understanding and delivery leadership to those decisions.
See what the organisation can deliver, where investment is exposed and which decisions need attention.

Programme management and service transitionWeb design, migration, configuration and hostingTECHNICAL DETAIL. EXECUTIVE CONSEQUENCES.
James’s experience connects the technology an organisation runs with the services it provides and the change it can realistically deliver.
Microsoft infrastructure, networks, configuration management and service dependencies. Establish what exists, who owns it and what a proposed change puts at risk.
Programme plans, financial controls, supplier commitments and operational readiness. Bring the technical work and business decisions into the same view.
Portfolio prioritisation, executive assurance and AI readiness. Test whether the plan is credible and whether the organisation has the information and capacity to act.

AI extends James’s technical and delivery practice. The focus is a useful change to a real process, with someone accountable for the result.
James uses AI-enabled analysis and synthesis for reporting, delivery patterns, risk visibility and executive communication. The judgement behind the recommendation remains human.
Explore AI readinessHis practical work spans cloud AI, local/private language models, agentic workflows and AI-assisted development. That experience helps frame sensible questions about data access, tool selection and review.
Explore AI enablementWebsite development and platform configuration provide a practical application of modern tools alongside established engineering disciplines. Scope, checks and handover still matter.
Website delivery and migration03 / HOW I WORK
A focused review, a recovery intervention or interim leadership. The scope follows the problem, with clear responsibilities and practical outputs.
Understand the commitments, constraints and risks. Listen to the people doing the work and test the evidence.
Make the trade-offs explicit. Define what needs to change, who owns it and which decisions need leadership.
Work with your teams to establish a credible plan, useful governance and a clear view of progress.

04 / THE PERSON BEHIND OAK LEAF
Technical depth.
Experienced leadership.
James brings 30 years of experience across technology, operations and delivery. His career spans hands-on infrastructure and technical consultancy through to leading complex programmes, portfolios and delivery teams.
James began in hands-on technical consultancy and enterprise training at Gateway, designing and implementing Microsoft and network infrastructure with customer engineering teams. Infrastructure migration in policing and configuration management at Deutsche Bank built his understanding of live services, dependency risk and the consequences of poorly controlled change.
His later work at Trustmarque and Sopra Steria covered infrastructure modernisation, secure government and defence transformation, service transitions and programme recovery. At Helping Hands, he stabilised a portfolio spanning technology, HR, finance and organisational change. His Serco role combines digital programme leadership with portfolio oversight, executive reporting and coaching a team of five.
James has led teams of up to ten project and programme professionals and has mentored others for more than a decade. He works with engineers, service owners, commercial teams and senior leaders to make responsibilities clear and decisions practical. His approach draws on PRINCE2, Agile and service management without imposing more process than the situation needs.
Professional development includes PRINCE2 Practitioner, AgilePM Practitioner / DSDM, ITIL v3 and ITIL 4, Lean Six Sigma Green Belt, MAPM and a CMI Level 5 Diploma in Management and Leadership (Distinction). His technical qualification history includes Microsoft MCSE and Cisco CCNA and CCNP. His Level 7 Senior Leader Apprenticeship / MBA pathway at Nottingham Trent University is ongoing.
