Worked on the apache/spark repository to enhance documentation for data source options, focusing on improving usability and discoverability for end users. Added detailed Markdown documentation for the inferTimestamp option in the JSON data source, enabling automatic inference of TimestampType and TimestampNTZType from string formats. Also documented the singleVariantColumn option across CSV, JSON, and XML sources, allowing entire records to be parsed into a single VariantType column. Emphasized cross-source consistency and reduced onboarding friction by aligning documentation with user workflows. Demonstrated technical writing and documentation tooling skills, collaborating with Spark SQL and data source teams to accelerate feature adoption.
