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.
