Hire the Best IT Networking Specialists

I'm the Level III IT consultant who works for other MSPs and IT consultancies — the senior hand you bring in for the hard problems junior techs escalate: network redesigns, cybersecurity hardening, server migrations, and emergency triage. 30+ years in the trenches, U.S. Navy trained, Top Rated with a 100% Job Success score. Based in the Chicago area / Northwest Indiana, with remote and on-site coverage nationwide. Where I go deep: - Networking & Security: Design, configure, and secure networks with SonicWall, Fortinet, Cisco/Meraki, UniFi/Ubiquiti, TP-Link Omada, and Netgear — firewalls, VLANs, VPNs, 2FA/MFA, site-to-site bridges. - Servers & Hosting: Nearly 30 years of cPanel/WHM, DNS, POP3/IMAP, Microsoft 365, and Google Workspace; Apache/PHP/MySQL on RHEL/CentOS/AlmaLinux for reliable hosting and maximum uptime. - Systems & Cloud: Windows Server 2025, Windows 11, Linux, and macOS; Azure/Hyper-V virtualization and AWS/GCP deployments — from design through deployment and ongoing operations. - Microsoft Stack: Microsoft 365 administration and migration, Entra, Intune, and Active Directory Group Policy. Industry experience: HIPAA-compliant IT for medical/dental, Dealer Management Systems for automotive groups, secure corporate networks, and structured wiring and access control for warehouses. How I work: Precise and methodical. Project-based engagements first, hourly for smaller targeted work. I bring clear status updates and a bias toward documenting what I change, so the next person — internal or external — can pick up where I left off. I coordinate across internal IT teams, third-party vendors, and contract boards when an engagement requires it. Background: Self-taught IT professional since 1997; U.S. Navy Aircrewman, Patrol Squadron 26 (VP-26), 1990–1995, earning a Navy Achievement Medal for technical expertise on a classified surveillance system. Network Operations Center engineer at eSignal/Interactive Data, 2000–2007. Founded Ateki LLC in 2002. If you need a senior consultant who can redesign a network, harden security, migrate a server room, or own the escalations your team is stuck on — and who shows up, communicates, and documents — let's talk about your project.
