About Holtzweb
Holtzweb was founded to provide modern technical solutions to customer problems - to give individuals and small businesses access to real solutions.
I'm Marcus Holtz — a systems engineer with 11+ years across the full stack. Web development, Linux servers, network infrastructure, cybersecurity, cloud environments, managed IT.
We are here to make your ideas work: you reach out with a question, something that's been sitting in the back of your head, something your last IT guy couldnt do, something that broke last Tuesday. I look at it, tell you what I think, and we figure out a path forward together. Sometimes it's a quick fix. Sometimes it turns into a longer project. Either way, reach out.
