Experience
Principal Engineer
Nov 2019 — Present · Bengaluru, IN
Developing firmware for Western Digital’s RapidFlex ASIC, architected for high-performance NVMe-over-Fabrics (NVMe-oF) over 100 GbE networks. This firmware seamlessly translates incoming NVMe-oF commands—delivered via RDMA (RoCEv2) or NVMe-TCP over 100 Gb Ethernet—into native NVMe transactions targeting PCIe-attached SSDs. By incorporating hardware-accelerated datapaths and leveraging 100G Ethernet connectivity, this solution enables ultra-low-latency, multi-Gbps throughput for composable, disaggregated storage infrastructures.Engineered and implemented advanced firmware features, including NVMe admin command processing, multi-core synchronization mechanisms, and streamlined peripheral access and control.Led the troubleshooting and resolution of complex firmware challenges involving peripheral interfaces and memory handling, resulting in improved system stability and performance.Contributed to the architectural design of firmware for multi-core ASIC platforms, focusing on optimizing concurrency, synchronization, and efficient resource utilization.Developed and maintained real-time firmware using OpenRTOS, ensuring scalable task scheduling and reliable inter-process communication in time-critical environments.Conducted board-level diagnostics using JTAG, oscilloscopes, and logic analyzers to support firmware development activities.Partnered with RTL, ASIC, and systems engineering teams to align firmware development with hardware architecture and project goals
