Senior🎓
Top SchoolSantosh Sivaraj is a seasoned solutions engineer with 13 years of systems and kernel-focused experience, currently driving platform and customer solutions at NVIDIA from Tamil Nadu. He brings deep low-level expertise across C, Python, Go and Rust, with a proven track record in kernel development, board bring-up, device drivers and performance-focused userland-to-kernel transitions from roles at IBM, Brocade, Mistral and HCL. His open-source contributions to pmem/ndctl show practical experience with platform memory, NUMA handling and tools that enable next-generation memory technologies like CXL and NVDIMMs. Calm under pressure and pragmatically humorous about shipping “high class bugs,” he pairs meticulous debugging with scripting that saves keystrokes and accelerates delivery. Comfortable both as an individual contributor and module lead, he combines hardware-near code instincts with an eye for streamlining tests and removing redundant checks.
