PROFILE
Joel Brownstein
Over a three-month period, contributed to the sdss/sdssdb repository by expanding and refining its database schema to support new scientific data requirements. Focused on backend development using Python and SQL, the work included designing new tables and models for allspect and multiplex data, refactoring ORM configurations with Peewee and SQLAlchemy, and implementing schema changes to improve data scalability and integrity. Added a boolean tracking flag for spectroscopic observations, enhancing traceability for MWM star data. All changes were delivered through structured commits, emphasizing maintainability and alignment across ORMs, and laying a foundation for improved analytics and future database performance.
