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
Windows in business
Microsoft Windows provides the desktop, server and endpoint foundation for many business environments. Companies use it for office workstations, identity management, file services, application hosting and secure access to internal systems. Its broad hardware and software support makes it a practical standard for mixed workplaces.
Core ecosystem
The technology connects closely with Active Directory, Group Policy, Microsoft Entra ID, Microsoft Intune and Windows Server. Strong experts also work with PowerShell, Microsoft 365, Azure, DNS, DHCP, virtualization and endpoint security. They understand how policies, identities, devices and applications interact across the environment.
Typical deliverables
- Windows workstation rollouts and configuration baselines
- Active Directory design, migration and Group Policy management
- Windows Server administration and application hosting
- Intune, Entra ID and endpoint management implementations
- PowerShell automation, monitoring and operational documentation
When expertise matters
Companies bring in freelance Windows specialists during migrations, office openings, restructuring and security improvement projects. They can replace legacy domain services, prepare device fleets for hybrid work or stabilize environments with recurring incidents. In Essen, this can support manufacturing, logistics, healthcare and service organizations that depend on dependable workplace systems.
Remote or on-site work
Many Windows tasks can be completed remotely through secure management tools, documented access and scheduled change windows. On-site presence helps with hardware handling, network dependencies, room-based deployments and user support. Teams in Essen should clarify access procedures, German or English language expectations, working hours and escalation paths before the engagement starts.
What quality looks like
Reliable professionals change systems carefully and explain the effect of each decision. They use least-privilege access, tested rollback plans, clear naming standards and useful documentation rather than relying on undocumented fixes. Look for experience with your Windows versions, identity model, security requirements and business applications, plus the ability to communicate clearly with technical and non-technical teams.
Frequently asked questions
Quick answers to the questions that come up most around Microsoft Windows.
Companies use Microsoft Windows for employee workstations, business applications, file and print services, identity access and server workloads. It also supports centralized policies, endpoint protection and integration with Microsoft 365 and Azure.
Microsoft Windows usually offers broader business application compatibility, hardware choice and integration with Active Directory and Microsoft 365. macOS can suit Apple-focused workplaces, while Linux is often selected for specific server, development or infrastructure workloads.
A capable Microsoft Windows expert often brings PowerShell, Active Directory, Group Policy, DNS, DHCP, Microsoft Intune and Entra ID knowledge. Familiarity with Microsoft 365, Azure, virtualization, backup and endpoint security is also valuable.
The right level for Microsoft Windows depends on the scope, risk and existing documentation. A workstation rollout may need focused endpoint expertise, while a domain migration or security redesign calls for a professional who can assess dependencies, test changes and plan recovery.
Much of Microsoft Windows administration can be handled remotely through secure management, monitoring and support tools. On-site work may still be useful for hardware, network access, device staging or business environments where local coordination is important.
Before working with Microsoft Windows, clarify the estate, identity provider, server and endpoint versions, access model, maintenance windows and success criteria. The professional should also understand compliance needs, critical applications, backup coverage and who approves production changes.
A strong Microsoft Windows specialist explains risks, documents the current state and proposes changes that can be tested and reversed. Ask for examples involving Group Policy, PowerShell, identity, security hardening or migrations similar to your environment.
For companies in Essen, Microsoft Windows expertise can support distributed offices, industrial workplaces, logistics operations and service teams with shared identity and dependable endpoint management. Agree in advance on remote collaboration, on-site availability and whether communication should be in German, English or both.
