Developed the foundational data model for NeMoBil mobility services, focusing on scalable schema definition and data modeling within the smart-data-models/incubated repository. The work centered on designing core entities such as Skill, Trip, TripProposal, TripRequest, User, and Vehicle, using JSON and YAML to define structures and provide adopter data examples. This initial schema established a stable baseline for future integrations, analytics, and onboarding of new data sources, aligning closely with architectural objectives. Although no customer-facing features were released, the groundwork laid during this period positioned the project for accelerated development and smoother downstream data ingestion in subsequent sprints.
