Technical Project Management at CHG Meridian AG
- CHG Meridian AG is a financial company focused on leasing in the areas of IT technology, logistics and medical technology and is regulated by BaFin. One part of the company is Return to Remarketing, where devices delivered to the technology center (notebooks, smartphones, tablets, etc.) are prepared for resale. The project I supported was responsible for enabling damage assessment of returned lease devices, documenting them visually in the form of pictures, enabling invoicing for the customer, and making the pictures available via the in-house customer platform. This was achieved through a combination of in-house development within the internal development department and the use of SaaS products. The second project was the transition of SaaS tendering software, purchased by the business unit, into the operations of the CHG IT department. Evaluation of security questions in relation to BaFin requirements, development of an authorization concept, implementation of single sign-on, documentation of the application in the CHG systems (CMDB, iKnow, etc.) and handover into operations.

About the technology
Core platform
Windows Server is the Microsoft server operating system used to run business-critical infrastructure on local networks and in data centers. It supports identity, storage, virtualization, and access control. Companies hire specialists to keep core services stable, secure, and easy to maintain.
Common uses
- Active Directory and domain services
- File, print, and application servers
- Hyper-V virtual machines and host management
- Remote access and secure internal services
- Patch and lifecycle planning
It is often the base layer for internal business systems, especially where Microsoft tools already shape the stack.
Ecosystem skills
Strong professionals know more than the OS itself. They work with PowerShell, Group Policy, DNS, DHCP, certificates, failover clustering, and backup tooling. They also understand how Microsoft Windows Server fits with Microsoft 365, SQL Server, and hybrid identity setups.
When to bring in help
Companies usually seek freelance expertise during upgrades, migrations, outages, security hardening, or when a legacy setup must be stabilized without downtime. In Essen, this often matters for manufacturers, logistics teams, healthcare groups, and service firms that need reliable internal systems and local language coordination.
What good specialists do
Good experts document the environment before they change it. They check roles, dependencies, naming, access rules, and recovery paths, then make updates in a controlled order. They leave behind clear runbooks, clean permissions, and a setup that another specialist can support later.
Signs you need one
- Domain login problems or trust issues
- Slow file shares or broken permissions
- Unsure patching or unsupported versions
- Virtual machines that need consolidation
- Security gaps around accounts and access
If those problems touch core services, a Windows Server specialist can find the cause faster than a generalist.
Frequently asked questions
Questions about Windows Server? Start with the answers below.
Windows Server is used to run core internal services such as identity, file sharing, access control, application hosting, and virtualization. It is common in Microsoft-heavy environments where teams need central management and predictable administration. Many companies also use it as the base for Active Directory, DNS, DHCP, and Hyper-V.
Windows Server is often the better fit when a company depends on Microsoft identity, Group Policy, or Windows-based internal tools. Linux is usually chosen for different stacks and administration styles. The right choice depends on the applications, security model, and the skills already in the team.
A strong Windows Server specialist usually knows PowerShell, Active Directory, Group Policy, DNS, DHCP, backup design, and virtualization. In many projects, knowledge of certificate services, failover clustering, and Microsoft 365 integration also matters. For complex estates, hybrid identity and security hardening are important too.
Bring in a Windows Server expert when you are upgrading a domain, moving roles, recovering from instability, or cleaning up an old environment. Outside help is also useful when the internal team is busy and the change must be handled carefully. The best time is before a small issue becomes an outage.
Yes, many Windows Server tasks can be done remotely if the environment is accessible and the change process is clear. That includes patching, role changes, PowerShell automation, and troubleshooting. On-site support in Essen can still help when hardware, network, or sensitive access checks need physical presence.
Look for clear notes, a structured change plan, and experience with the exact version and roles you run. A good Windows Server freelancer explains risks, dependencies, and rollback steps before making changes. They should also be comfortable with logs, event tracing, and basic performance checks.
For many legacy applications, Microsoft Windows Server is still the safest and most practical choice. It can keep older business software running while you plan a controlled migration. A specialist should review support status, security exposure, and the cost of keeping the system in place.
Prepare a list of servers, installed roles, versions, backup routines, and any open incidents. A Windows Server specialist works better when you can share diagrams, admin access paths, and a clear list of what must not be interrupted. That saves time and reduces risk in the first review.
