Can Dcc worked on reliability and privacy enhancements across the cloudquery repositories, focusing on backend development and data transformation using Go. In cloudquery/plugin-sdk, Can addressed intermittent test failures by introducing a dataOnClose field to the BatchUpdater, allowing tests to accurately track processed data when Close() is called. For cloudquery/cloudquery, Can implemented JSON path-based field obfuscation and removal in the core transformer, leveraging gjson and sjson for efficient JSON processing without full marshaling. These changes improved test stability, data privacy, and performance, demonstrating a thoughtful approach to debugging, JSON processing, and robust backend engineering within a short timeframe.
