Graduation: Modernization of internal development tools

Graduation: Modernization of internal development tools

Description of assignment

The MWS team is seeking an intern to support the modernization of our internal development tools. We use .NET-based (WPF) applications that interact with various microservices. For local development and testing, we rely on stubs to simulate external components. Currently, these stubs are built on the outdated .NET Framework 4.8 and share a legacy library that is no longer maintained.

The current setup lacks compatibility, maintainability, and flexibility, which negatively impacts developer productivity and slows down bug reproduction and testing.

The goal of the assignment is to research and implement a new shared .NET library for stubs, migrate existing stubs to .NET 8, and ensure they follow modern software development practices, including object-oriented programming (OOP), modularity, and maintainability. The new solution should be web-based, support Docker deployment, and be compatible with future Kubernetes hosting.

Research Question:
How can we design and implement a modern, maintainable, and flexible .NET-based stub framework to support local development and testing of microservice-integrated workstation applications?

Department description

The MWS team is part of the VIBES Core within Vanderlande’s Airport domain. We focus on developing and maintaining workstation applications that support baggage handling operations. Our work involves close collaboration with other software teams, system architects, and product owners across the VIBES Agile Release Train (ART). The intern will be integrated into a multidisciplinary Scrum team, working on real-world projects alongside experienced .NET/Java developers, a quality engineer, and a scrum master. The environment encourages learning, teamwork, and active contribution to ongoing development initiatives.
