The IuK Justice Center's task is to create a future-proof IT infrastructure for the Baden-Württemberg judiciary. This includes, among other things, the automated legal dunning procedure. Across Germany, more than four million applications for the issuance of a dunning notice are processed annually. The system went into operation in 1982 and has been continuously developed ever since. As part of the modernization of the dunning procedure, the system is to be migrated to a modern base.
My task was to prepare the replacement of the mainframe system. For this, I created a microservice-based architecture for a middleware that initially handles communication between client and mainframe and access to the database. This middleware is intended to be deployed on an OpenShift platform in the future. The middleware was designed to be continuously extended so that it can gradually take over the mainframe's tasks. Various open-source systems such as Keycloak and the Grafana Observability Stack were integrated during the implementation.

The IT System House of the Federal Employment Agency provides employees of the 1,300 counseling centers in Germany with a tool called ALLEGRO to record applicants for basic services and their calculation-relevant personal circumstances, manage them, determine their need and pay out a corresponding benefit according to the currently valid legislation. ALLEGRO is a Swing-based rich/fat client communicating with a Java EE application server (Payara) in the backend.
As one of about 50 Java software developers in the Allegro team, my tasks were to migrate individual aspects of the underlying monolith to current technologies or extract them into separate (micro)services, adapt the system to regularly changing legal regulations, and locate, analyze and fix bugs. As a knowledge manager, I also ensured through organizing presentations, knowledge transfers, and documentation that the necessary knowledge is present in the team and distributed.

AOK Systems provides with the oscare application the basis for managing contracts for many statutory health insurers in Germany. Oscare covers the entire spectrum of processes of a statutory health insurance. The module is built in two parts. One area is based on a SAP Netweaver backend with Web DynPro frontend. The second area on an ABAP backend with Fiori frontend. Necessary data exchange between the areas is done via database replication.
My task was to implement a new module of the suite to support contracts for primary care centered healthcare. This included frontend and backend as well as data exchange with the ABAP team.
