Lädt …Lädt …Lädt …Certified IT Specialist · Founder of RamzX
I'm a certified IT specialist and have been building websites, platforms and scripts for more than 14 years — with deep experience in virtualization and Linux. Since 2016, I've been building and running IT infrastructure for mid-sized businesses with RamzX — from Heidelberg, with no call center and no subcontractors.
What drives me: IT that simply works. Systems my clients don't have to think about, because they run. I'm the person who built the project and who still picks up the phone when something isn't right.

Four principles I apply consistently in every project
After the assessment, you get a binding fixed-price quote. What's in it gets built: no change orders, no explanations of why it "took longer after all."
I deliver all services personally. No subcontractors, no team you never meet. Full accountability — one point of contact.
I recommend what's right for you — not what earns me the highest margin. Sometimes the cheaper solution is the better one. And I'll tell you so.
When we're done, you get a written report: what was built, how it's configured, and what makes sense next. No black-box IT.
Started as a self-employed IT specialist in Heidelberg, with the first Proxmox projects for local businesses.
First Sophos firewall deployments. Built expertise in site-to-site VPN, IPS and network segmentation.
Network infrastructure for a multi-location practice chain. Central UniFi controller over a VPN mesh.
Built a DIN EN 15380 data pipeline for Deutsche Bahn (DB AG), via Takowi GmbH.
Proxmox HA cluster in production. Development of Winget Deployer, Conjure, and Röntgen.
IT infrastructure, security, and web development for mid-sized businesses, with a direct point of contact and a fixed price after analysis. Operating as RamzX since October 2026.
I founded RamzX because I saw how many companies pay for IT that doesn't really work — or for support they can never actually reach. I wanted to do it differently.

No hold music. I reply personally — usually within 2 hours on business days. Customers with a maintenance contract can reach me via their emergency number.
