Worked on reliability and privacy enhancements across the cloudquery repositories, focusing on backend development and data transformation using Go. In cloudquery/plugin-sdk, addressed intermittent test failures by adding a dataOnClose field to BatchUpdater, allowing tests to accurately track processed data when Close() is called. In cloudquery/cloudquery, implemented JSON path-based field obfuscation and removal within the basic transformer, leveraging gjson and sjson for efficient JSON processing without full marshaling. Updated record updating logic and documentation to support these changes. Demonstrated strong debugging and testing skills, delivering one new feature and resolving a key bug within a one-month period.
