Worked on the yugabyte/yugabyte-db repository to enhance database reliability and upgrade processes over a two-month period. Addressed string manipulation reliability by updating C and SQL-based functions to return empty strings instead of NULL and correcting overflow handling, with comprehensive regression tests to ensure correctness and prevent future issues. Improved backend stability by refining type handling in core AGTYPE logic. Later, delivered a robust upgrade path for Apache AGE 1.6.0 on PostgreSQL 15, introducing migration artifacts, upgrade guidance, and deployment safeguards. Updated SQL scripts, Docker configurations, and documentation to support safer upgrades, demonstrating strengths in backend development and database management.
