Schleupen.CS 3.0 – Architecture and Framework

Period: 04/2016 – 12/2019
Role: .NET Developer
Client: Schleupen SE
Team size: 6
Person days: 150

The Schleupen.CS software solution is a distributed application with numerous functional and technical components, aimed at providing a standardized and configurable software solution for the energy and water sector across different market roles. The "Architecture and Framework" team works directly with the enterprise architect and handles all cross-cutting concerns of the backend. The team's tasks involve creating cross-team best practices, design patterns, and a framework for over 100 developers, so that the architecture is implemented as consistently as possible across the many different applications.

My contributions to the project::
  • Development and consolidation of the application architecture
  • Reducing dependencies between teams through better modularization of the framework
  • Development of SOAP services for platform components
  • Analysis, design, and implementation of a new deployment solution based on Puppet
  • Writing and automating CoffeeScript (a JavaScript dialect) unit tests

Stabilization of Asynchronous Communication – Business Components

Period: 11/2017 – 01/2018
Role: Software Developer
Client: Schleupen SE
Team size: 5
Person days: 100

When distributed systems communicate asynchronously and messages are lost, it is very difficult to find out where they go missing. Since the previous project had shown that the errors were no longer in the platform components, the team's task was to provide solutions within the framework to support the business developers.

My contributions to the project::
  • Concept and implementation of the Transaction Outbox Pattern in the framework
  • Documentation of the Transaction Outbox Pattern
  • Training sessions on idempotency and the Transaction Outbox Pattern

Stabilization of Asynchronous Communication – Platform

Period: 07/2017 – 10/2017
Role: Software Developer
Client: Schleupen SE
Team size: 5
Person days: 100

When distributed systems communicate asynchronously and messages are lost, it is very difficult to find out where they go missing. The task of the project was to analyze the existing code and identify and fix weaknesses in the platform components. Solutions were also developed to increase the confidence of testers and developers in the platform components.

My contributions to the project::
  • Concept and implementation of the Test Message Pattern
