Prasad Joshi is a seasoned systems software engineer with 14 years of experience specializing in Linux kernel, virtualization, and high-performance storage and migration systems, currently a Senior MTS at Nutanix. He has engineered core IO paths, distributed caching and migration features for cloud data mobility at PrimaryIO and CacheBox, and contributed kernel and tooling patches to projects like KVM, QEMU, OSv and Illumos. His work on OSv's VFS—adding symlink, openat and eventfd support—highlights a deep comfort with low-level OS internals and cross-project collaboration. A master's researcher in KVM and a history of shipping production-grade firmware and kernel modules (including ZFS on Linux ports), he blends rigorous TDD and benchmarking with pragmatic performance tuning. Based in Pune, he pairs strong C/C++ systems expertise and familiarity with Facebook libraries and VMware stack with a knack for turning complex distributed IO requirements into verifiable, high-performance implementations.
