Sara Schönherr-Senior Software Developer with a Focus on UI/UX

Development of an interactive prototype for the concept of an AI-supported Enterprise Architecture Management tool. The goal was to present complex relationships between IT systems, business processes, and departments in a way that is easy to understand and to support decision-making in the context of IT transformations.

The prototype combined data-driven analyses with guided questions and interactive visualizations. A central part was the integration of a RAG process to provide domain-specific EAM knowledge in context. The focus was on quick idea validation, user-centered interaction design, and the technical feasibility of a scalable overall concept.

Design and development of a user-centered digital product to improve appointment organization in table tennis. The goal was to give players a simple and fast way to register and unregister for training sessions and matches, thereby increasing reliability and planning certainty for teams and coaches.

Focus on a low-threshold user experience design with a mobile-first approach that supports spontaneous interactions and encourages early feedback. The application was implemented as a modern web solution with a clear information architecture and intuitive operation.

Software solution for accounting for relevant customer contracts according to IFRS 15 in a telecommunications environment. The goal of the project was the automated detection, evaluation, and processing of contract changes relevant to accounting across multiple connected source systems. Contract and customer data were consolidated, validated from a business perspective, and the resulting business cases were transmitted to a connected SAP target system.

A special focus was placed on ensuring data quality and traceability in a business-critical environment. For this purpose, a web-based user interface was developed that transparently displays business cases, aborts, and validation errors and allows manual correction as well as export of affected data. The solution was gradually integrated into an existing system landscape and completely replaced a predecessor solution.
