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
Containers
Docker is used to package software and its dependencies into containers that run the same way across laptops, test systems, and production. Strong experts help companies avoid environment drift and keep releases repeatable.
It is common in service-based systems, internal tools, and cloud-native applications where teams need clean handoffs between development and operations.
Images and builds
- Write Dockerfiles that produce small, stable images
- Tune build layers and caching for faster delivery
- Handle multi-stage builds for lean runtime containers
- Set up image tagging and versioning rules
Freelance specialists often improve builds after a migration, when pipelines become slow, or when a product needs a cleaner deployment path for teams in Essen and remote engineers alike.
Compose and local setups
Docker Compose is a common part of the ecosystem for running linked services such as web apps, APIs, databases, and message brokers. It gives teams a practical way to start realistic local environments without complex setup work.
This is useful for onboarding, testing feature branches, and keeping development environments aligned across many experts.
Operations and delivery
- Connect Docker to CI and deployment workflows
- Set environment variables, secrets, and network settings
- Troubleshoot container startup, health checks, and logs
- Prepare images for Kubernetes or other runtime platforms
Companies bring in freelance Docker expertise when releases are inconsistent, builds are hard to reproduce, or old server setups need to move into containers with less risk.
What strong experts do
A strong Docker professional understands image design, runtime behavior, Linux basics, and how containers fit into delivery pipelines. They know when to keep a container simple and when to split responsibilities across services.
They also document clearly, because clean instructions matter when teams share work across locations and time zones.
Essen projects
In Essen, Docker work often supports teams that build internal business tools, platform services, and modern web applications. Remote collaboration is common, but on-site workshops can help when the container setup is tied to local infrastructure or a legacy environment.
For searchers, Docker and Docker Engine are usually the key terms, while Docker Compose often appears in project briefs and handover notes.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Docker.
Docker is used to package an application together with the libraries and settings it needs, so it runs consistently in different environments. Companies use it for local development, test environments, delivery pipelines, and production services. It is especially useful when teams want the same setup on every machine.
Docker containers are lighter than virtual machines because they share the host system kernel. That usually makes them faster to start and easier to move through build and delivery pipelines. Virtual machines still matter when full isolation or a different operating system is required.
A strong Docker specialist should know Dockerfiles, image layering, container networking, volumes, and Compose. Practical Linux knowledge matters too, because most problems show up in process handling, permissions, logs, or startup behavior. Experience with CI/CD is often part of the job as well.
Many Docker tasks can be handled remotely, especially image work, Compose setups, and pipeline fixes. On-site collaboration in Essen can help when the work touches local infrastructure, internal access rules, or a legacy system that is harder to inspect from outside. The best setup depends on the project, not the location alone.
Bring in Docker help when builds are unreliable, deployments differ from one environment to another, or an application needs to be containerized for the first time. Freelance specialists are also useful when an internal team needs a short burst of expertise for migration, hardening, or pipeline cleanup. They can step in without a long hiring process.
Docker is the core container technology and toolset. Docker Compose is a separate tool used to define and run multi-container setups, such as an app plus a database plus a cache. Many projects use both, but they solve different problems.
A Docker freelancer often works with Git, CI systems, Linux shells, registries, and orchestration tools such as Kubernetes. Depending on the stack, they may also touch Nginx, databases, message queues, and secret management. The exact mix depends on how the containers are deployed.
Look for clean image design, clear Dockerfiles, stable Compose files, and a sensible approach to tags, logs, and health checks. Good Docker experts explain trade-offs, not just syntax, and they leave behind setups that other specialists can maintain. If they can improve reliability without adding unnecessary complexity, that is a strong sign.
