Prevented infrastructure incidents from disrupting service for 500–1,000 users by monitoring and supporting Windows Server, VMware, Microsoft 365, network, storage, security, and cloud environments across 100+ customers. Reduced the risk of recurring outages by tracing failures to their root causes across Active Directory, Domain Controllers, Group Policy, DFS, IIS, Exchange, VMware, SAN storage, DNS, DHCP, TCP/IP, and network services. Protected critical workloads from untested recovery assumptions by administering Veeam backups, performing virtual-machine and data restores, validating recovery procedures, and correcting failures before recovery was needed. Preserved application availability during host failures and planned maintenance by supporting VMware vMotion, High Availability, clustered resources, and automatic failover through VMware vCenter. Reduced exposure on vulnerable systems by reviewing security findings, prioritizing high-risk assets, coordinating operating-system and application patching, and hardening servers before production deployment. Prevented unauthorized access to customer systems and data by administering MFA, Conditional Access, role-based permissions, user privileges, firewall rules, and DMZ security controls. Limited the impact of compromised accounts by investigating suspicious logins, revoking active sessions, resetting credentials, enforcing MFA, and adjusting Conditional Access policies. Prevented storage, compute, and network constraints from becoming service outages by monitoring capacity, performance, utilization, traffic patterns, interface errors, and availability trends. Reduced network troubleshooting time by analyzing packet captures, WAN performance, VPN failures, interface conditions, and traffic data through Meraki Dashboard, SolarWinds, Auvik, ThousandEyes, and other monitoring platforms. Protected email availability and security by administering Exchange Online and on-premises Exchange, monitoring mail flow, resolving delivery failures, blocking malicious senders and domains, and supporting mailbox migrations. Avoided hours of repetitive administrative work by developing and modifying PowerShell scripts for Exchange migrations, Active Directory reporting, Entra ID data collection, and bulk account operations. Prevented migration and upgrade failures from becoming prolonged outages by executing Microsoft 365 migrations, tenant-to-tenant migrations, Windows upgrades, VMware upgrades, and server replacements with tested rollback procedures. Minimized service disruption across approximately 75–100 weekly incidents by restoring authentication, email, server, storage, VPN, firewall, DNS, DHCP, and WAN services within established SLA expectations. Protected production workloads from storage degradation by administering Nimble and HPE SAN platforms, monitoring capacity and performance, resolving faults, and coordinating storage operations with VMware and Veeam. Reduced dependence on undocumented technical knowledge by creating maintenance procedures, disaster-recovery instructions, SOPs, knowledge articles, and escalation documentation. Prevented complex incidents from stalling at the first level of support by providing in-depth technical direction, mentoring administrators, and guiding teams through infrastructure troubleshooting and recovery. Reduced project risk across overlapping initiatives by coordinating implementation steps, testing, maintenance schedules, technical dependencies, rollback plans, and stakeholder communications.
