Summary
👤
Senior🎓
Top SchoolJoel Fernandes is a systems software engineering leader with 17 years of deep Linux kernel and embedded systems experience, currently leading systems software at NVIDIA after a nearly decade-long tenure as a Staff Software Engineer at Google. He is a prolific kernel contributor with expertise spanning CPU scheduling, synchronization, real-time systems, KVM, device drivers, memory/DMA, and power/performance optimization, and has applied that knowledge across products at Amazon Lab126, Texas Instruments, and others. Joel has a strong hardware-software intuition—he designs and debugs prototype boards and low-level firmware, and has solved production-blocking eMMC and power measurement challenges firsthand. An active open-source maintainer and contributor, his work on iovisor/bcc (including a critical section tracer and Android build fixes) highlights his focus on observability and portability for kernel analysis. A frequent conference speaker and published researcher with an MS in Computer Engineering, he combines rigorous academic training (3.97 GPA) with a track record of shipping robust, high-performance kernel features in complex, multi-vendor environments.
