Worked on foundational schema enhancements in the iTwin/bis-schemas repository, focusing on improving pond data modeling and enabling draft-based site configuration management. Developed and consolidated schema changes by introducing new pond properties such as pond_id, pond_name, and pond_type, and added the OpenSiteDraft schema to support draft management workflows. The work emphasized robust schema definition and data modeling using TypeScript, ensuring consistency and reducing schema drift for downstream applications. No bug fixes were logged during this period, as the primary effort centered on establishing a reliable groundwork for future features and maintaining alignment across evolving data models within the project.
