WORK HISTORY
Senior Staff Software Engineer @Marvell Technology
Santa Clara, CA, US
Technically led and contributed individually to the development of optimized system software for PCIe DMA drivers and 5G transport software at Processor BU, implemented system software using C (tested using python). Executed various simulation experiments to identify bottlenecks in fast path implementation and proposed solutions. Collaborated with hardware teams for coprocessor design. Facilitated design wins. Supported on multiple customer issues. Mentored and technically guided- Designed and implemented PCIe DMA device software for OCTEONTX and Odyssey SoC using Linux kernel PF device driver, DPDK PMD VF driver, ODP DMA VF driver, delivered these to multiple top-tier telecom and data center customers with multi-millions-dollar revenue. Resolved customer issues- Designed and implemented various VPP features using ODP-DPDK and guided a team of engineers from other locations for various features for a top-tier 5G telecom customer- Made modifications to StrongSwan for customer use-case.
