Worked on the maths/moodle-qtype_stack repository to enhance the reliability and maintainability of backend systems, focusing on database query improvements and lexer robustness. Addressed SQL errors and runtime warnings by refactoring queries for better readability and performance, and improved variable handling within class properties to ensure stable database interactions. Tackled lexer crashes caused by malformed exponent expressions by introducing validation checks and expanding unit test coverage to guard against regressions. Utilized PHP and SQL for backend development and database management, emphasizing code quality and robust error handling. The work resulted in more stable quiz interactions and a more maintainable codebase.
