About David

I design and deliver Microsoft infrastructure — Active Directory, M365, Entra ID, Azure — and lead the IT programs that make those architectures real.

As founder of Hacked24 I have completed 150+ projects, resolved 10,000+ security incidents, and hold a 4.98/5 client rating. I work as IT Architect, IT Project Manager, and Fractional CIO — whichever role the engagement needs.

What I deliver:
Active Directory & Microsoft Infrastructure — AD DS architecture, hardening and clean-up, Entra ID (hybrid identity / Azure AD Connect), AD migration and consolidation. I design from scratch or rescue environments that have grown without governance.

Microsoft 365 (M365) — Tenant architecture and migration (tenant-to-tenant, cross-forest), Exchange Online and Teams cutover, SharePoint governance, Intune / Autopilot rollout, Microsoft Copilot deployment with Purview and DLP controls.

IT Project Management & Program Delivery — End-to-end delivery of infrastructure, cloud and AI programs: scope, budget, risk, vendor and stakeholder management, steering committee reporting. Azure landing zones, M365 consolidation, Copilot rollouts, M&A IT integration.

Fractional CIO / Head of Infrastructure — 1–2 days/week senior IT leadership: roadmap, Microsoft licensing optimisation, NIS2 / DORA / ISO 27001 readiness, AI governance, board reporting. No full-time headcount required.

Who I work with: Heads of IT, CIOs, CTOs, CEOs and COOs at 50–10,000-seat companies. MSPs and Microsoft Partners needing senior subcontract capacity for AD / M365 / Azure engagements.
