Experiences

I had collected many experiences in many topics over my duration as an IT administrator.
These experiences reach over server; network; windows administration, management of mail systems and web services.
On this side, you will see especially selected experience topics, that I selected.

Windows administration

Windows is one of the main parts of the modern working environment.
Because of these importance I also work and administrate it almost daily.

Especially I specialized my skills in the education sector, where you always have to be one head ahead of the students, that work with the computers.
Thanks to these circumstances I always learn more and more ways, how students wants to outsmart the configured policies.

The on premise alternative to the Microsoft Azure platform Microsoft Entra ID, is the Microsoft Active Directory.

This solution is very important to the German education sector, because Microsoft services are more than controversial, in case of the GDPR regulations.
Because of these circumstances, I work at the time on a Microsoft 365 alternative, that is totally self-hosted and uses the MS ADDS services to manage the users centrally.

Server administration

Virtualization is one of the main topics to use your On-Premises or dedicated server efficient and to save energy and costs.

Virtualization and the use of a hypervisor is the today’s way to go.
I specialized on the open source platform Proxmox VE to create virtualization platforms, because they also offer a very easy to use backup server and are completely open source.

Web hosting is one of the main parts to a modern company.
What would a company be, without an internet presence?

I maintain a wide range of web applications and can help you to fit your hosting space to the needs, that you have.

Phone systems sound kinda old, and they also are.
But they are as well a critical point of communication for businesses, in view of the fact that a customer can call you in every situation he has.

As well, I also had experiences in these sectors of communication technology.
I already worked on many telephone systems and administratively supervise them.
Especially I work with 3CX and FreePBX / Sangoma Telephone systems and be 3CX Basic Engineer of v20.
