During December 2025, Ufadiz focused on strengthening the data model for the hexlet-basics/hexlet-basics repository by addressing a critical database schema issue. He updated foreign key columns from integer to bigint across eleven columns in six tables, aligning them with primary key types to resolve type mismatches. This work, implemented using Ruby, ActiveRecord, and Ruby on Rails, improved data integrity and ensured consistency across cross-table relationships. Ufadiz’s disciplined approach included careful SQL schema migrations and thorough code reviews, resulting in a more robust foundation for future scalability and smoother migrations. The depth of this work reflects strong database design skills.
