Worked on the rclone/rclone repository to enhance the reliability and performance of the S3 backend, focusing on backend development and memory management using Go. Addressed a critical memory leak by ensuring that strings extracted from S3 API responses were cloned, preventing large payloads from being unnecessarily retained in memory and improving garbage collection efficiency. Updated several functions to consistently clone metadata and object key fields, further optimizing memory usage across S3 operations. The work demonstrated a strong understanding of cloud storage systems and low-level memory handling, contributing to a more robust and efficient backend for rclone’s S3 integration.
