Client-facing technical role spanning managed services, systems engineering, Microsoft cloud, infrastructure, advisory, presales and project delivery.

• Lead broad systems reviews across Microsoft 365, servers, networking, endpoints, security, backup, DR, governance and lifecycle risk.
• Develop technical roadmaps, recommendations, Statements of Work, estimates and implementation plans.
• Deliver Microsoft 365, Modern Workplace, infrastructure and migration work from discovery through implementation, validation and handover.
• Act as an escalation resource across M365, Windows Server, identity, Citrix/RDS, networking, endpoint and business application issues.
• Build PowerShell and Microsoft Graph tooling for administration, migration, archive, mailbox, reporting and validation workflows.
• Contribute to QBRs and executive discussions, translating technical findings into practical priorities and investment recommendations.
• Support peers through technical review, troubleshooting and solution guidance.
• Create and maintain technical documentation, knowledge-base articles, procedures, user guides and project handover material.

My first substantial professional IT role, combining hands-on support with internal systems administration and business-process improvement.

• Provided on-site IT administration, technical support and user training.
• Maintained supplier and client relationships and worked with third-party support providers.
• Diagnosed hardware and software faults, completed component and server hardware upgrades, and managed backups.
• Supported Windows domain users, Remote Desktop, Office 365 and early exposure to Active Directory, Hyper-V and SQL Server.
• Improved efficiency by developing integrated applications and customising CAD-based databases.
• Worked with AutoCAD / ProgeCAD and business productivity applications in a manufacturing / construction-related environment.

Commercial interior fit-out work, including projects with Armitage Williams and Higgs Builders.

• Applied practical problem solving to deliver quality outcomes under time pressure.
• Worked independently, showed initiative and prioritised work across active job sites.
• Built a hands-on foundation in framing, carpentry, joinery and general construction.
• Landscaping work including paving, fencing, garden lighting, drainage systems and laying turf.

The practical background is relevant to how I work today: understand how the parts fit together, diagnose the real problem, and leave the result working properly.

Administration, migration, design and troubleshooting across Microsoft 365, including identity, licensing, mail flow, guest/external access, collaboration, tenant configuration and complex service issues.

Modern endpoint deployment, management and security across Windows estates, including device enrolment, Entra join, policy troubleshooting, application/configuration work, SOE design and lifecycle planning.

Core infrastructure engineering and troubleshooting across Windows Server and hybrid environments, including directory services, name/address services, replication, virtualisation, remote application platforms and storage.

Practical network and security work including firewall/VPN troubleshooting, segmentation, identity controls, least privilege, email protection, audit investigation, secure remote access and environment security reviews.

Purpose-built automation for repetitive or risky operations. Examples include filesystem archiving, mailbox/data movement, Microsoft 365 bulk administration, CSV-driven workflows, reporting, validation and staged preview/cleanup processes.

Assessment and testing of backup and recovery capability, with emphasis on proving recoverability rather than treating a successful backup job as the end result.

Whole-environment assessment and client advisory: current-state reviews, risk identification, requirements gathering, solution design, Statements of Work, project estimation, technology roadmaps and executive-level recommendations.

Senior troubleshooting and delivery ownership across customer environments, supporting peers and coordinating vendors and stakeholders when an issue or project crosses multiple technical layers.

I genuinely enjoy creating and maintaining useful documentation. At work this includes technical notes, KB articles, procedures, system-review material, implementation notes, user guides and handover documentation. At home I maintain my own BookStack knowledge base for lab systems, services and projects.

Comfortable communicating with technical teams, end users, vendors and business decision-makers. I work well as part of a team, but I am equally comfortable taking ownership of a problem or project and working independently through to an outcome.

Built PowerShell and Microsoft Graph tooling for archive workflows, mailbox/data movement, Microsoft 365 administration, reporting and validation. Where operations carry risk, I favour preview/dry-run modes, detailed logging, verification and staged cleanup.

Review whole client environments rather than isolated products, connecting technical condition and lifecycle risk to practical remediation priorities and business-facing recommendations.

Discovery, planning and delivery for Microsoft 365, SharePoint and endpoint initiatives, including migration design, stakeholder coordination, implementation, validation, documentation and handover.

Practical improvements across identity, privileged access, guest/external sharing, email security, endpoint controls, firewall policy and network segmentation, balancing risk reduction with supportability and user impact.

Backup and disaster-recovery reviews, restore validation, dependency mapping and DR testing designed around the question that matters: can the business recover the service when it actually needs to?

Investigate difficult issues by correlating logs, audit data, network behaviour and application symptoms across layers rather than stopping at the first plausible explanation.

I run a multi-host home lab used for Linux, containerised applications, storage, networking, reverse proxying, media services, monitoring and recovery experimentation. I also maintain my own BookStack knowledge base with setup guides, troubleshooting notes and service documentation.

Experimenting with local language models, GPU workloads, image-generation pipelines, transcription and self-hosted AI interfaces.

Building small tools, interfaces and interactive prototypes to test ideas quickly, including browser-based utilities, Three.js concepts, automation front ends and an ongoing interest in VR / Unity development.

I am the note-taker for our D&D sessions and maintain structured campaign records including session summaries, timelines, characters, NPCs, locations, loot and open story threads. I also host Foundry VTT and enjoy designing and testing game and card mechanics.

Playing guitar, songwriting and music projects alongside album artwork, visual concepts and music-video ideas — a useful creative counterweight to infrastructure work.

I still enjoy hands-on practical work away from a screen — camping, caravanning, DIY and general hardware tinkering — which connects back to my construction and trade background.

My technical background started with hands-on hardware, support and internal IT administration, then grew into systems engineering, cloud and consulting.

I also developed integrated applications and customised CAD-based databases to improve efficiency in my pre-CodeBlue IT role.

I am a family man, married with three children. Family is a big part of life outside work, alongside camping, caravanning, music, D&D, technology projects and building things.

I value being dependable, approachable and able to switch between serious technical work and communicating with people in a normal, down-to-earth way.

I am self-motivated, approachable and quick to learn. I enjoy problem solving and finding ways to make systems and processes more efficient.

I am comfortable working as part of a team or independently, and I am used to taking ownership of difficult issues while keeping clients, users and other engineers informed. I communicate technical information clearly and stay methodical when working under pressure.
