Over a two-month period, contributed to workflow enhancements in the hopps-app/hopps and thiws24/equipli repositories by refactoring and clarifying BPMN process models using XML. Focused on improving the expense reimbursement and member invitation workflows in hopps-app/hopps, the work emphasized clearer participant naming, consistent message flows, and maintainable event handling to enhance user-facing process clarity. In thiws24/equipli, delivered updates to the reservation-to-return workflow, introducing robust inter-process communication and refining lending logic for future automation. The approach centered on workflow design and management, prioritizing maintainability and scalability while addressing process correctness rather than explicit bug fixes during this period.
