Worked on the awslabs/mountpoint-s3 repository to deliver an observability enhancement focused on tracing inode lifetimes during FUSE mknod operations. Implemented a debug print statement in Rust within the file system layer, allowing developers to monitor newly created inode numbers without altering existing behavior. This instrumentation improved visibility into inode lifecycle events, supporting faster troubleshooting and performance analysis while laying the foundation for future optimizations. The work demonstrated skills in debugging, file system internals, and observability practices. No bugs were fixed during this period, as the contribution centered on maintainability and enhanced diagnostic capabilities rather than functional or behavioral changes.
