Filesystem Developer for Unity in Dell-EMC's Core Technologies Division. In support of inline-compression, implemented high quality core functionality and tests for a data-path cache, including: "Instant" snapshot (replica) creation without cache-flush, read & write path with and without snaps present, cache bypass. Primary developer of filesystem team unit/system test framework. Designed, implemented and provide ongoing support for a new developer-test platform that reduced the edit-build-test cycle for filesystem developers by 10x and achieving ~90% code coverage. Filesystem quality tools: data integrity validation and I/O generation tools that support inline-compression.
