Worked on the rommapp/romm repository to deliver enhancements for gamelist metadata management, focusing on enabling support for comma-separated metadata attributes. This feature improved the flexibility and scalability of game metadata, allowing for more effective search, filtering, and analytics capabilities. The technical approach involved evolving the metadata schema and implementing robust CSV attribute handling within the backend, all developed using Python. The work demonstrated skills in backend development and data parsing, with changes carefully integrated through Git-based workflows. No major bugs were addressed during this period, as the primary focus remained on expanding metadata handling to support future analytical needs.
