✅ I help organizations secure their Microsoft environments, meet compliance requirements, and protect the contracts that drive their business. I’m the founder of Davis Tech Pro, a Microsoft Cloud Security and compliance consultancy focused exclusively on the Microsoft ecosystem. I help organizations secure, prove, and maintain compliance in regulated environments. I’ve led CMMC Level 2 compliance engagements for defense contractors and currently oversee active clients progressing through early assessment phases. While certification is still in progress, both engagements are aligned with CMMC requirements and timelines. I’ve also hardened Microsoft 365 environments for healthcare organizations handling 50,000+ patient records, deployed Zero Trust architectures across 300+ endpoints, and implemented Microsoft Sentinel SIEM solutions that reduced incident response time by 70%. If your organization runs on Microsoft in a regulated environment, I help you secure it, prove it, and keep it that way. 🛡️ CMMC & DoD Compliance (Level 1 & Level 2) For defense contractors, compliance directly impacts revenue and contract eligibility. I support contractors through full readiness, remediation, and audit preparation: ✔ CMMC Level 1 & 2 gap assessments ✔ NIST 800-171 aligned remediation planning ✔ SSP and POA&M development ✔ CUI handling and protection ✔ GCC High migrations and secure architecture ✔ Evidence preparation for C3PAO assessments Goal: help you pass assessments, reduce risk, and protect contracts. 🏥 HIPAA Compliance in Microsoft 365 I configure Microsoft environments to meet HIPAA safeguards without disrupting operations: ✔ Microsoft Purview sensitivity labels and DLP ✔ Conditional Access and MFA via Entra ID ✔ Audit logging, retention, and eDiscovery ✔ Secure PHI handling across M365 ✔ Compliance documentation and audit support 🔐 Endpoint Security & Zero Trust I implement Zero Trust security using Microsoft tools: ✔ Intune (MDM/MAM) deployment and policies ✔ Defender for Endpoint onboarding and response ✔ Conditional Access and identity protection ✔ CIS/NIST-aligned endpoint baselines Every user, device, and access point is continuously verified. 📊 Microsoft Sentinel (SIEM) & Threat Detection I build Sentinel environments for real-time visibility: ✔ Data connectors across systems ✔ Custom KQL detection rules and threat hunting ✔ Incident response automation (Logic Apps) ✔ Centralized monitoring and analytics ⚙️ Automation & AI Workflows I improve operations inside Microsoft environments: ✔ Power Automate workflows ✔ RPA for repetitive processes ✔ AI-driven workflows for operations and internal systems 🌐 SharePoint & Microsoft Web Solutions ✔ Power Pages portals for client/partner access ✔ SharePoint document management for compliance (CUI/PHI) ✔ SharePoint intranets with structured architecture and SPFx 🎯 Who I Work With ✔ Defense contractors (CMMC) ✔ Healthcare organizations (HIPAA) ✔ Financial and regulated industries ✔ Mid-market Microsoft 365 environments ✔ Teams needing a specialist, not a generalist 🤝 How I Work • Clear scope and structured execution • Compliance aligned with real operations • Maintainable, long-term security systems • Direct communication and accountability I take on a limited number of clients to ensure high-quality delivery. 🚀 Let’s Secure Your Environment If you need help with CMMC, Microsoft security, Zero Trust, AI automation, or Microsoft-based web systems, I can help you move quickly and confidently. 📩 Message me to discuss your environment and compliance goals.

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.

If you need cloud infrastructure built, deployments automated, integrations shipped, or an environment locked down — and you need it done properly, not just planned — that's where I come in. 20 years of real engineering across AWS, Azure, and GCP. I've built things that are still running in production at NielsenIQ, Verizon, Seacoast Bank, and Data443. Not advisory work. Actual delivered infrastructure. What I build: Cloud Infrastructure and DevOps: - AWS and Azure infrastructure (VPCs, AKS, EKS, networking, IAM, hybrid connectivity, VPN gateways) - Infrastructure as Code: Terraform, Bicep, ARM templates — from scratch or migration - CI/CD pipelines, GitHub Actions, containerized workloads (Docker, Kubernetes) - Serverless: Lambda, Azure Functions, API Gateway, event-driven architectures - Multi-cloud design, cost optimization, cloud migration Security and Compliance: - Microsoft Sentinel, SIEM buildouts, KQL detection rules, SOAR playbooks - Zero Trust architecture: Entra ID, Conditional Access, PIM, MFA enforcement - AWS Security Hub, GuardDuty, IAM hardening, compliance baselines - SOC2, HIPAA, NIST, CMMC — implementation, not just gap analysis Integrations and Automation: - REST API integrations, custom connectors, middleware (Node.js, Python) - M365, Defender, Purview, Intune management and automation at scale - GCP services, multi-cloud patterns, SaaS integrations At NielsenIQ I saved $750K/year on security tooling and shipped two production Sentinel connectors now live in Microsoft's Content Hub. At Verizon and Seacoast Bank I designed Zero Trust architectures that are still running today. At Data443 I built AWS marketplace connectors that integrate with CrowdStrike, SentinelOne, and Cyren threat intelligence pipelines serving 500+ clients. I work US hours, communicate clearly, and I actually show up. Tampa, FL. Certs: Azure Solutions Architect Expert, Azure Security Engineer, AWS SA Pro, AWS Security Specialty, MCSE+Security
