Worked on the move-coop/parsons repository to enhance the MySQL connector by introducing a configurable connection timeout feature. This addition allowed users to specify a timeout duration for establishing MySQL connections, forwarding the value to mysql.connector.connect and aligning its behavior with existing Postgres and Redshift connectors. The implementation focused on consistency and reliability in production ETL pipelines, reducing the risk of hanging connections and supporting service-level agreements. Developed a comprehensive suite of unit tests in Python to validate default, explicit, and forwarded timeout scenarios, demonstrating strong skills in Python, database management, and test-driven development within a collaborative open-source environment.
