Worked on the RaviTambade/TFLAssessment repository to enhance data governance and analytics readiness by refining the database schema. Focused on converting the gender and difficulty fields to ENUM types, this change improved data integrity by enforcing valid value constraints and clarified semantics for downstream processes. The approach involved careful data modeling and database design, with attention to migration readiness and comprehensive documentation using Markdown. No critical defects were reported during this period, allowing full attention to schema improvements. These updates established a foundation for scalable reporting and simplified future validation, aligning the data model with evolving analytics and product requirements.
