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
Service boundaries
Microservices is an architectural approach that splits a large application into small, independently deployable services. Each service owns a clear business capability and communicates through APIs or events. Teams use it to build scalable commerce, banking, logistics and industrial systems while limiting the impact of changes.
Core architecture
A reliable design starts with bounded contexts, explicit contracts and independent data ownership. Specialists define synchronous REST or gRPC calls where direct responses matter, and asynchronous messaging where resilience and loose coupling matter. They also plan service discovery, configuration, retries, timeouts and failure isolation.
Ecosystem and tooling
The surrounding stack often includes Spring Boot, Spring Cloud, .NET, Node.js, Docker and Kubernetes. Delivery work may cover API gateways, Kafka or RabbitMQ, OpenTelemetry, Prometheus, Grafana and centralized logging. Strong professionals connect these tools into repeatable build, test, deployment and observability workflows.
Typical delivery work
- Decompose a monolith without breaking critical business flows
- Create service contracts, APIs and event schemas
- Containerize services and prepare Kubernetes deployments
- Introduce automated testing, CI/CD and release controls
- Trace requests and diagnose distributed failures
When expertise matters
Companies bring in freelance specialists when a monolith has become difficult to release, teams need independent ownership, or platform reliability is under pressure. They can assess whether a service split is justified, guide a migration roadmap and improve an existing estate. For Essen-based teams, remote delivery works well when documentation, working agreements and overlap for collaboration are clear.
What strong professionals deliver
The best specialists balance domain design with operational discipline. They make trade-offs visible, keep interfaces stable and avoid creating a distributed monolith. Look for evidence of production migrations, contract testing, secure service-to-service communication, incident response and practical guidance for teams across development and operations.
Frequently asked questions
Everything clients usually want to know about Microservices, in one place.
Microservices are used to build applications as a set of focused services that can be developed, deployed and scaled independently. They suit complex products such as marketplaces, payment systems, logistics platforms and connected industrial applications, provided the organization can manage the added operational complexity.
Microservices offer independent releases, technology flexibility and targeted scaling, while a monolith is usually simpler to test, operate and change early in a product’s life. The right choice depends on domain boundaries, team structure, reliability needs and the organization’s operational maturity.
Microservices and service-oriented architecture both divide systems into services, but Microservices usually emphasizes smaller ownership boundaries, independent deployment and decentralized implementation choices. SOA often relies more heavily on shared enterprise infrastructure and centralized governance.
A strong Microservices specialist should understand API design, domain-driven design, distributed data, containers and cloud infrastructure. Useful adjacent skills include Kubernetes, CI/CD, observability, Kafka or RabbitMQ, security, automated testing and incident management.
Microservices work needs practical experience with distributed failure modes, service boundaries and production operations, not just familiarity with frameworks. The required depth depends on whether the assignment covers a new architecture, a staged monolith migration or the stabilization of an existing service landscape.
Microservices projects can be delivered remotely when teams use clear API contracts, architecture records, shared dashboards and disciplined release processes. Essen-based companies should also agree on language, collaboration hours, access controls and occasional on-site workshops where domain discovery benefits from direct contact.
Microservices may be a poor fit for a small product, a single tightly coupled team or a system without a clear need for independent scaling and releases. A modular monolith can provide strong boundaries with less deployment, networking and monitoring overhead.
Ask a Microservices specialist to explain a real boundary decision, a failed release or an incident and the trade-offs involved. Good answers cover contract versioning, data consistency, observability, rollback strategy and how the design helped teams deliver safely rather than focusing only on framework names.
