Senior🎓
Top SchoolNageswara Sastry is a Senior Software Engineer at IBM Systems with over two decades in IT and 14 years focused on Linux functional verification, virtualization and security testing. He architects and automates complex regression suites for KVM, libvirt and Power systems, has authored thousands of lines of test automation, and helped identify hundreds of kernel and virtualization bugs. An active contributor to prominent open-source test projects such as the Linux Test Project and tp-libvirt, he adapts tests across kernel versions and validates memory hotplug and hugepage behaviors. He mentors engineers, led a dynamic test-suite reduction effort using coverage data, and has presented his work at Linux Conference Australia. Based in Bengaluru, he blends deep hands-on fuzzing and security testing experience with pragmatic test-architect responsibilities across IBM’s hardware platforms. Colleagues rely on him for turning flaky or platform-specific failures into robust, version-aware test cases.
