Storage Domain Expertise: Deep knowledge of the storage stack — high availability, caching, flash, RAID, dedup/compression, filesystems, block storage, I/O paths, latency/throughput trade-offs, consistency, and replication — including designing test strategies for complex storage features. Test Automation & QA Methodology: Strong hands-on Python test automation skills, familiarity with IO tools (vdbench, Orion, IOmeter) and database technologies (Oracle/SQL, OOP concepts), and solid grounding in QA best practices, failure/corner-case scenario design, and root-cause analysis.
