Senior🎓
Top SchoolSean Mccall is a pragmatic systems and application administrator with 9 years of hands-on experience modernizing infrastructure for airports, nonprofits, and enterprises. Currently the senior application administrator for Charlotte Douglas International Airport, he’s the primary technical resource for baggage handling and supports complex server, OS, and third‑party application ecosystems. Sean has a strong track record migrating identities and mail systems to Azure AD/Office 365, consolidating tenants, and implementing secure access (PIM, SAML, conditional access) while cutting costs through cloud and networking optimizations. He pairs deep operational knowledge—SD‑WAN/SASE, AD restructuring, VPN and replication fixes—with a curiosity-driven, problem-solving approach that digs into root causes rather than band-aid fixes. Colleagues rely on him for practical improvements that reduce spend and increase reliability, such as network redesigns and automation of provisioning workflows.
