I provide enterprise-grade infrastructure reliability backed by a fully insured limited company. While low-cost freelancers experiment on your tenant, I deliver architect-level security, compliance, and zero-downtime migrations.
Core Specializations for Enterprise Environments:
• Azure Cloud Architecture: Cost-optimization audits and high-availability design that typically pay for themselves within the first billing cycle.
• Identity & Access Management (IAM): Hardening Active Directory and Entra ID (Azure AD) to implement Zero-Trust frameworks.
• M365 Tenant Governance: Secure deployment, compliance mapping (GDPR/HIPAA), and complex cross-tenant migrations.
•Security & Liability: Every engagement is backed by professional liability insurance and rigid data-handling protocols.
I do not compete on price; I compete on the elimination of risk. My services are designed for organizations that view their IT infrastructure as a strategic asset, not a cost center.
Some of my Azure, M365, GCP and on-premises technology skills:
• Microsoft 365
