Developed core asset management features for the gautschr/3D-modelling repository, focusing on backend infrastructure to support 3D asset ingestion and standardized handling. Implemented a robust upload system enabling users to add 3D models, laying the foundation for scalable asset workflows within the 3D modelling and theatre modules. Established a centralized theatre asset library with explicit directory scaffolding and repository hygiene, including .gitignore management to ensure consistent asset organization. Leveraged Python for backend development and Git for version control, emphasizing maintainable file handling practices. The work delivered two foundational features, setting up a structured environment for ongoing asset lifecycle management.
