Worked on the snowflakedb/snowflake-jdbc repository to improve the reliability of integration testing by addressing a bug in OAuth scopes construction. Focused on ensuring that the correct role is used when generating OAuth access tokens, the solution aligned test behavior with production standards and enhanced authorization accuracy. Using Java and JDBC, the developer refined the integration test suite to reduce false negatives and minimize CI instability caused by improperly scoped tokens. This work demonstrated a strong grasp of OAuth and integration testing practices, resulting in more accurate test outcomes and a smoother continuous integration process for the Snowflake JDBC project.
