What I take care of for you

I'm your partner for the IT that has to run in the background so your business keeps working smoothly and securely. Servers, networks, security, clients or automation — I make sure it all works together cleanly.

Systems

Servers and systems are the foundation for everything that happens in your business — whether they run on-premise or in the cloud. Your systems should fit your business strategy, not the other way round.

  • Windows and Linux servers
  • On-premise or in the cloud
  • Microsoft 365, Active Directory and Entra ID
  • Virtualization, backup and monitoring

Security & Networks

With ransomware and phishing attacks a constant threat, IT security matters more than ever. I take care of firewalls, VPN, zero-trust access and segmented networks so your business stays protected.

  • Firewall, network, Wi-Fi and VPN
  • MFA and permission concepts
  • Backup, recovery and contingency planning

Communication

Information has to move quickly and reliably between systems and between people. Alongside the technical work, communication is the real heart of the job. I explain things so you can make a decision without having studied IT yourself.

  • Communication between systems and people
  • Explanations without the jargon

One contact.
No ticket system.

Servus — I'm Sascha.

I've worked in IT for over ten years, but computers have fascinated me since I was fourteen. Training as an IT specialist for system integration taught me how much depends on different systems working together cleanly. Every company, every school, every local authority has its own processes and requirements. I look at how your business actually works, then build a solution that fits you.

I'm a fan of clear, direct communication. No ticket system, no rotating contacts, no long waits. I take an interest in how you work and use what I have to help. You bring the problem; together we take care of the solution.

In Practice

Typical tasks I handle for businesses.

  • From on-prem servers to Microsoft 365

    From the on-premise environment to the cloud — I take care of the whole Microsoft side, whether that's Windows Server, Active Directory, or Microsoft 365. Making sure everything works together cleanly and the permissions are right.

  • Linux & Server Operations

    Servers that just run and nobody notices — that's really the goal. I set up Linux servers, keep them current, and fit them cleanly into existing Windows environments when that's what's needed.

  • There's always a way

    Not every problem has an off-the-shelf fix. That's when I build something that actually holds up and fits into what's already there.

  • Security

    IT security matters more than ever with ransomware and phishing attacks on the rise. I take care of firewalls, VPN, zero-trust access, and segmented networks to keep your business protected.

  • Backup & recovery

    A backup is only interesting once you actually need to restore it. A job showing green every night doesn't prove a restore will work when it matters.

  • Schools & Local Government

    IT in schools and local government runs differently than in a regular business — tight budgets, aging hardware, and strict data protection rules. Through my training and years of working closely with these organizations, I know these quirks firsthand and what actually matters there.

Frequently Asked Questions

What does an IT freelancer in Munich cost — and is the first consultation free?

Yes — the intro call and the initial review are free. I'd happily drop by for a coffee, we'll look at your IT setup together and map out the next steps. What ongoing support costs after that depends on scope and effort, and we always go over it upfront.

Do you work on-site in Crailsheim as well?

Yes, of course. Munich is my home base, but I'm regularly on-site in Crailsheim and the Hohenlohe-Franconia region too.

Which types of companies do you work with?

It fits best if you don't have your own IT team, or have one that's stretched thin, and want one steady contact instead of another ticket in a queue.

How fast do you respond to IT problems?

Depends on how urgent it is. My top priority is getting you back to work without having to think about it. The bigger the emergency, the faster I'm on it.

How is a freelancer different from an IT service company?

A larger IT firm gives you more people behind you, but also more changing faces. With me it's the other way round: one person who actually knows your systems, but no 24/7 team in the background. Depending on what you need, one fits better than the other.

I'm not an IT expert — is that a problem?

No, quite the opposite — I'll explain things so you can make a decision without having studied IT yourself. If I ever slip into jargon, just ask.

IT you can rely on.

Best case, you don't have to think about your IT at all, because it just works. It starts with a short conversation — I take a look at what's going on, then we both see if it's a fit.
