Worked on the tobymao/sqlglot repository to enhance SQL dialect compatibility, focusing on both feature development and bug fixes over a two-month period. Addressed cross-dialect SQL translation by implementing TRY_DIVIDE transpilation for Databricks, ensuring division by zero returns NULL and aligning behavior with other dialects. Improved ISO8601 date parsing by introducing a dedicated parsing expression for Presto/Trino and refactoring the base generator to centralize casting logic, supporting Snowflake, Spark, and additional dialects. Leveraged Python and SQL for data engineering and database management tasks, resulting in more reliable, maintainable, and portable SQL code across diverse database environments.
