Software Engineer at DataDirect Networks improving Lustre management and enabling zero-downtime upgrades across 200+ node clusters.

Message

At DataDirect Networks, I enhance the Rust-based EXAScaler Management Framework for the Lustre parallel distributed file system. I’ve resolved reliability issues and refined upgrade workflows to support zero-downtime upgrades across 200+ node clusters.

At IBM, I developed features and fixed defects in IBM Storage Protect. I investigated customer-reported crashes across Windows, AIX, and Linux using crash dumps, stack traces, and runtime diagnostics.

Earlier at DataDirect Networks, I maintained cluster management tools for GRIDScaler and developed Bash scripts for in-place upgrades and configuration backup and restore. I also increased test coverage by 10% in a Robot Python automation framework.

I contributed four upstream changes to Lustre and worked on DDN SFA firmware, including NVMe-oF on Zephyr RTOS-based microcontrollers. My work has also included utilities for processing system traces and detecting network discrepancies.
