Last position:
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
Identity control
Active Directory is the core identity system for many Windows-based company networks. It stores users, groups, computers, and access rules in one central directory. Strong specialists keep logins consistent across offices, apps, and shared services.
What it supports
- User and group management
- Domain join and access control
- Group Policy rollout
- Certificate, DNS, and trust setup
- Hybrid identity with cloud services
It is used in offices, plants, and multi-site environments where access must stay reliable and auditable.
Ecosystem around it
Active Directory work often sits with Windows Server, Group Policy, DNS, DHCP, and PowerShell. Many projects also touch file shares, print services, and remote access. In modern setups, AD DS is often linked with Microsoft Entra ID for hybrid sign-in and account sync.
When companies bring in help
Freelance experts are useful during migrations, domain redesigns, permission cleanup, and security hardening. They also help when logins fail, policies conflict, or old domains need careful restructuring. Companies in Essen often need on-site support for local infrastructure, while routine administration can be handled remotely.
What good specialists do
A strong Active Directory professional works methodically and documents every change. They understand replication, OUs, delegation, password policy, and troubleshooting across clients and servers. They also know how to reduce risk when changing core identity services.
Good fit signs
- Legacy domains need cleanup or consolidation
- Group Policy is hard to maintain
- Access issues affect daily work
- A Windows Server upgrade is planned
- Hybrid identity needs a stable base
The best specialists can explain trade-offs clearly and keep the directory service stable while the business keeps running.
Frequently asked questions
Everything clients usually want to know about Active Directory, in one place.
Active Directory is used to manage identities and access in Windows-based environments. It centralizes users, groups, computers, and policy settings so employees can sign in and reach the right resources. Companies rely on it for consistent access across offices, servers, and internal applications.
AD usually means the on-premises directory service built into Windows Server, while Microsoft Entra ID is the cloud identity service. Many organizations use both in a hybrid setup, with AD handling local network control and Entra ID supporting cloud sign-in. A good specialist knows where each one belongs.
A Active Directory project often needs outside help during migrations, domain restructuring, or access cleanup. It also comes up when Group Policy becomes hard to manage or when authentication problems affect daily work. Freelance support is useful when the change must be careful and well documented.
A strong Active Directory specialist usually also knows Windows Server, DNS, Group Policy, PowerShell, and basic networking. In hybrid environments, Microsoft Entra ID and identity sync tools are often part of the work. Troubleshooting skills matter just as much as setup skills.
A AD task that only involves routine user or group changes can be handled by a generalist. Domain redesigns, trust relationships, or migrations need someone who has worked through real directory failures before. The more the project affects sign-in and policy, the more important deep experience becomes.
Most Active Directory tasks can be done remotely if the specialist has secure access and clear change windows. On-site work in Essen is useful when the issue involves local infrastructure, hardware, or coordination with internal teams. Many companies use a mix of both.
A good Active Directory professional asks about domain structure, replication, policy scope, and rollback before making changes. They should be able to explain risks in plain words and show how they test each step. Clean documentation and careful change control are strong signs of quality.
The first Active Directory issues are often login failures, broken permissions, messy group structure, or outdated policies. Companies also want help with password policy, account lifecycle, and trust or replication problems. The right specialist focuses on the root cause instead of patching symptoms.
