Summary
🤩
Rockstar🎓
Top SchoolNirmoy Das is a Senior System Software Engineer with 11 years of experience building and maintaining high-performance Linux kernel subsystems, specializing in graphics drivers, networking, and platform enablement. He has driven GPU driver stability and performance at Intel and AMD—contributing upstream to the Linux kernel DRM/XE tree—and recently joined NVIDIA to enable Grace CPU support on Linux. Prior roles at SUSE and Cavium strengthened his kernel, container networking (notably Cilium), and embedded systems expertise, blending backend, DevOps, and device driver work. An active open-source maintainer, his patches appear in widely used projects like torvalds/linux and cilium, where fixes ranged from GPU reset optimization to IPv6 and NAT64/NAT46 handling. Based in Greater Nuremberg, he pairs deep systems knowledge with a track record of shipping production fixes that improve stability across vendor and community kernels.
