Worked on the tursodatabase/turso repository to address critical issues related to AUTOINCREMENT integrity in SQLite-backed databases. Focused on preserving AUTOINCREMENT behavior during schema changes, such as dropping columns, and ensured the sqlite_sequence was properly reset after operations that alter AUTOINCREMENT columns. Added targeted regression tests to verify that ID continuity is maintained following schema modifications, thereby reducing migration risks and supporting reliable data integrity. Improved test reliability by conditionally skipping ALTER COLUMN regression tests when unsupported by SQLite. Utilized Rust and SQL, applying database management and testing expertise to deliver robust, maintainable solutions that lower operational support costs.
