About

Staff Embedded Linux / Linux Kernel Engineer specializing in system performance and kernel/device driver development. 12+ years delivering Qualcomm-based platforms (IPQ40xx, IPQ50xx, IPQ60xx, IPQ80xx, IPQ54xx, IPQ95xx, IPQ53xx, QCN760x, MSM8996, SDX55, SDX65) from first bring-up to production reliability. I work end-to-end across boot flow, kernel + Device Tree, core subsystems, peripheral enablement, profiling and tuning, and deep debug. I’ve contributed 400+ patches on Code Aurora and I’m comfortable owning ambiguous issues through root cause, fix, and upstream-quality delivery in close collaboration with HW/FW/QA. My strengths include PMU/perf-driven profiling and bottleneck analysis; tuning latency and throughput across CPU, memory, and I/O paths; architecture work across SMMU/IOMMU, DSU, cache/coherency, DDR bandwidth/latency, and NoC contention; and kernel/driver engineering across PCIe/SDIO/I2C/SPI/UART along with interrupts, DMA, clocks, pinctrl, regulators, and runtime PM. I’m also strong in reliability work (oops/panic, lockups, deadlocks, memory corruption) using ramdump/crash analysis, Trace32/JTAG, and GDB.I
