About Steven Holman

I’m a Principal Cloud & Messaging Architect with a career spent modernizing large‑scale Microsoft 365, Exchange Online, and identity platforms across financial services, federal government, and global technology organizations. My work centers on designing secure, scalable, and compliant architectures that enable organizations to evolve—whether that means multi‑tenant M365 models, hybrid Exchange modernization, identity realignment, or AI‑driven operational transformation.Across 20+ years, I’ve led enterprise programs that reshape how organizations communicate, collaborate, and secure their data. I’ve architected solutions for Fortune 100 enterprises, engineered secure communications for the Executive Office of the President, authored the DoD BlackBerry STIG, and guided cloud and mobility modernization at Wells Fargo.My expertise spans multi‑tenant M365 design patterns, cross‑tenant collaboration and isolation, DNS/domain provisioning at scale, Azure AD/Entra ID identity alignment, and large‑scale migrations (25k–100k users). I partner closely with IAM, Security, DevSecOps, and program leadership to validate feasibility, identify architectural risks, and deliver decision‑ready guidance for executive stakeholders.I’m passionate about bringing clarity to complex architectural decisions—whether that’s evaluating identity vs. email separation, modeling mailbox migration throughput, defining non‑functional requirements, or aligning future‑state designs with regulatory isolation needs. I also leverage PowerShell, Graph API, and AI‑enabled automation to improve reliability, compliance, and operational efficiency across cloud environments.At my core, I’m a builder of systems, relationships, and outcomes. I thrive in environments where architecture, security, and business strategy intersect—and where the right design unlocks scale, resilience, and modern collaboration for tens of thousands of users.If your organization is navigating M365 modernization, multi‑tenant strategy, or cloud‑driven transformation, I’m always open to connecting.
