IT help for North Shore homes and small businesses
I'm Gerti, a working system administrator. I take on-site calls in Wilmette, Evanston, Skokie, and Chicago for slow computers, unreliable WiFi, Microsoft 365, servers, and Azure. You pay for the visit. No contract, no monthly plan.
What I can help with
The everyday problems that stop you from working, and the business systems behind them.

Cleaning up infected machines and closing the gaps that let it happen.

I bring that same experience to homes and small businesses that need reliable IT support without the price tag or paperwork of a managed IT firm. My goal is clear, honest, effective help, with no long-term contracts and no hidden fees.

Questions people ask
Don't see yours? Ask me directly.
How does billing work?
You're billed for the visit. There's no contract, retainer, or monthly plan, so you only pay when something needs fixing.
What's the difference between on-demand IT support and managed IT services?
Managed IT services are an ongoing monthly contract with proactive monitoring. On-demand support means you call when something's wrong and pay for that visit only.
Do I need a full-time IT person for a small business?
Most businesses under 50 employees don't have enough day-to-day IT work to justify a full-time hire. On-demand support is usually more cost-effective, because you pay for help when something actually needs it.
Why is my office WiFi so slow?
Usually it's too many devices on one router, outdated equipment, interference from walls or other electronics, or an internet plan that's too small for the number of people using it. Moving the router or updating its firmware sometimes helps. If it keeps happening, the network setup is worth a closer look.
Why is Microsoft 365 not syncing?
Sync problems in OneDrive, Outlook, or SharePoint usually come from a lost connection, an expired sign-in, a file open in two places at once, or a OneDrive app that needs a restart. If a whole team has the same problem, it's usually permissions or licensing.
How often should a small business back up its data?
Automatically and daily for anything business-critical, with one copy kept away from the office, either in cloud storage or on an offsite drive.
