I design and migrate mission-critical cloud infrastructure for organizations that need compliance, security, and reliability more than anything else. Most clients come to me for email migrations or Zero Trust architecture. All of them end up with infrastructure that becomes an organizational standard, not a one-off project. WHAT I DO - Cloud Security & Compliance Audits - Assess your infrastructure against CMMC, FedRAMP, HIPAA, or SOC 2 requirements. Identify gaps with clear remediation roadmap and timeline. - GCC High & FedRAMP Migrations - Design and execute zero-downtime migrations to federal cloud. I've reduced migration timelines by 67% (4 months → 6 weeks) using automated toolchains and repeatable processes. - Zero Trust Architecture Design & Implementation - Build identity-first security frameworks with Entra ID, Conditional Access, PIM, and passwordless MFA. Aligns to CMMC, FedRAMP, and federal security standards. - Large-Scale Infrastructure Architecture - Design landing zones, governance models, and cost optimization frameworks for 100+ subscriptions. I've owned $4B+ in infrastructure across global enterprise environments. HOW I WORK Phase 1: Discovery & Assessment (1 week) Audit current infrastructure, compliance posture, security gaps Deliver detailed assessment with prioritized recommendations Phase 2: Architecture & Planning (1-2 weeks) Design the target state (landing zones, governance, identity) Create implementation roadmap with milestones and timelines Get stakeholder alignment before building Phase 3: Implementation (2-8 weeks, depends on scope) Execute migrations or deployments using Infrastructure as Code Automated testing, compliance validation, zero-downtime cutover Documentation and team handoff Phase 4: Validation & Hardening (1 week) Security assessment post-deployment Runbook documentation for ongoing operations Knowledge transfer to your ops team RECENT RESULTS GCC High Migration for Healthcare Organization Challenge: 4-month timeline, no repeatable process, unfamiliar with federal requirements Approach: Designed end-to-end framework, automated policy deployment, built repeatable process Outcome: Reduced timeline to 6 weeks (67% faster). Framework became company standard. Client now qualifies for $50M+/year federal contracts. Large-Scale Infrastructure for Global Healthcare Network Challenge: $4B spend across 100+ subscriptions, ad-hoc setup, escalating costs Approach: Designed landing zones, governance models, automated onboarding Outcome: $200K+ annual savings. 99.99% uptime for patient-critical systems. Infrastructure scaled from weeks to days per new clinic. Zero Trust & Identity Architecture for Enterprise Challenge: Shadow IT, compromised accounts, slow access provisioning, no modern controls Approach: Conditional Access, Entra External ID, passwordless MFA, automated policies Outcome: Password attacks eliminated. External access now audited and time-limited. Access provisioning 3 days → 2 hours. WHEN I'M A GOOD FIT ✓ Migrating to federal cloud (GCC High, SIPERNET, AWS GovCloud) ✓ Need to achieve CMMC Level 1/2 or FedRAMP compliance ✓ Building Zero Trust architecture and need expert guidance ✓ Managing 50+ Azure subscriptions, need governance/cost optimization ✓ Healthcare system, government contractor, or regulated financial firm WHEN I'M NOT ✗ Need a small changes to quick website or landing page ✗ Want M365 email/Teams setup without infrastructure strategy ✗ Need "just fix this fast" without proper architecture If any of this resonates, let's talk more. Share your infrastructure challenge, compliance requirement, or timeline and I'll send back a 2-3 slide assessment and next steps. No fluff, no BS. Just honest technical assessment.

I build and secure cloud environments Microsoft 365, Azure, AWS, and Oracle Cloud for regulated enterprises across US, UK & GCC. Banking, healthcare, real estate, insurance, government. 12 years of this, 5 years in banking. 150+ cloud and hybrid projects: AD migrations, M365 rollouts, workload migrations across Azure, AWS, and Oracle Cloud. 90,000+ users migrated across AD and M365. 15,000+ endpoints secured with Intune. Most of my work is fixing what somebody else started, then expanding it into something that actually holds together. WHERE CLIENTS CALL ME IN: - AD forest and Exchange hybrid migrations stalling on public folders, shared mailboxes, or mail flow coexistence - Tenant-to-tenant migrations stuck at 60% licensing, mail flow, and device cutover not sequenced - Defender deployments generating 400 low-fidelity alerts daily instead of catching real threats - Conditional Access rollouts that broke legacy apps and got rolled back - Entra ID migrations where Hybrid Join looked healthy but SSO silently failed for 30% of users - Azure AD Connect sync bleeding duplicate objects after a merger, nobody willing to touch the attribute flow - AWS and Oracle Cloud alongside Microsoft infrastructure no unified identity, no security baseline, IAM policies nobody documented RECENT ENGAGEMENTS: - Hybrid identity and M365 E5 rollout for a 2,500-user fintech and banking group, UAE and KSA: AD forest cleanup, Entra ID Conditional Access, PIM, MFA, Defender XDR, Intune, Autopilot for Windows, Apple Business Manager for iOS and macOS corporate and BYOD separation, zero-touch provisioning, delivered against PCI-DSS, SAMA, and NCA ECC. - HIPAA-aligned M365 + Intune + Defender rollout for a 1,200-user healthcare group: Apple Business Manager, Autopilot, Conditional Access, MFA, SSO, DLP - AD + Exchange hybrid to Exchange Online for a regional insurance group: Mailbox cutover, public folder decommission, mail flow coexistence, SPF/DKIM/DMARC rebuild - Tenant-to-tenant migration with Oracle Cloud integration for a 600-user UAE holding: Entra ID, Intune, Defender, licensing reconciliation, zero-downtime cutover - Zero Trust identity and GPO lifecycle framework for a SAMA-regulated bank: Conditional Access, PIM, break-glass, policy decomposition, baseline rebuild, audit-ready docs - Multi-tenant MSP security baseline across 5-10 client tenants: Defender for Business, Intune templates, GDAP cleanup, partner center hygiene - M365 Copilot readiness and Purview baseline for a Gulf enterprise: Sensitivity labels, SharePoint access governance, DLP guardrails before tenant-wide enablement CORE SERVICE AREAS: - Active Directory and hybrid identity: forest consolidations, GPO rationalization, Azure AD Connect, Hybrid Join, PTA/PHS, ADFS decommission - Exchange and messaging: on-prem to Exchange Online, tenant-to-tenant, public folder migration, mail flow coexistence, SPF/DKIM/DMARC - Azure: CAF landing zones, hub-and-spoke networking, Azure Policy, ExpressRoute, VPN - AWS: multi-account landing zones, IAM Identity Center, VPC, Security Hub, GuardDuty, Control Tower - Oracle Cloud: OCI IAM, tenancy design, Identity Domains, Entra ID integration - M365 security and compliance: Defender XDR, Purview DLP, insider risk, sensitivity labels, eDiscovery GDPR, UAE PDPL, ADGM, VARA, HIPAA, ISO 27001, NIST CSF - Entra ID: Conditional Access, PIM, MFA, passwordless, B2B/B2C - Sentinel and SOAR: KQL analytics, Logic App playbooks, threat hunting, SOC runbooks (25+ builds) - Intune: Autopilot, compliance policies, BYOD, Apple Business Manager, Android Enterprise - Copilot and AI: M365 Copilot readiness, Security Copilot, Azure OpenAI deployment - MSP: GDAP, Lighthouse, per-tenant baselines, cross-tenant reporting HOW I RUN AN ENGAGEMENT: One-week discovery first: posture scan, identity inventory, licensing audit, policy review. What looks like a CA rollout is usually a CA rollout plus three legacy apps that break, a missing break-glass process, and an Intune compliance gap nobody noticed. Scoping honestly up front is the difference between clean delivery and halfway through and stuck. Environments span Microsoft 365, Azure, AWS, and Oracle Cloud, often in combination. Compliance delivered: PCI-DSS, SAMA, NCA ECC, HIPAA, ISO 27001, GDPR, SOC 2, NIST CSF, UAE PDPL.
