Robert C.

I provide remote IT support and systems administration for small and mid-sized businesses — Microsoft 365, Active Directory, endpoint management, and the day-to-day troubleshooting that keeps people working. Most of my experience comes from being the person an entire organization called when something broke. Over three years I handled Tier 2/3 support across a multi-site environment: user accounts and permissions, Microsoft 365 and mailbox issues, DNS and DHCP, secure remote access, printers, endpoint problems on Windows, macOS, and Linux, and the escalations nobody else could resolve. What I can help with: • Microsoft 365 administration — user setup, licensing, mailboxes, Teams, security configuration • Active Directory and Group Policy — accounts, groups, permissions, lockouts, cleanup • Employee onboarding and offboarding, including fully automated workflows built with PowerShell and API integrations • Endpoint management, patching, and vulnerability remediation across Windows and Linux • Network troubleshooting — TCP/IP, DNS, DHCP, LAN/WAN, FortiGate firewalls, VPN and ZTNA remote access • Security tooling — CrowdStrike Falcon, endpoint management platforms, KnowBe4 phishing simulations and training • SSL/TLS certificate renewals and installation • IT documentation, SOPs, and knowledge base articles I'm CompTIA A+, Network+, and Security+ certified, and a Certified CMMC Professional (CCP) — I've implemented NIST SP 800-171 controls in a DoD contract environment, so if you're a defense contractor with compliance requirements, I understand what you're dealing with. I respond quickly, explain things in plain language rather than jargon, and I'd rather fix the root cause than close the same ticket eleven times. Send me a message with what you're running into and I'll tell you honestly whether I'm the right fit.
