Developing firmware (ATF, UEFI, MCUs) and Linux kernel drivers for NVIDIA BlueField DPUs.

Contributed to a wide software stack in C for multi-core SoCs as part of the Core-OS organization. This included development of hardware abstraction layers, Linux kernel support, device drivers, U-Boot support, firmware based on FreeRTOS, and hardware bring up.

Maintained responsibilities from my previous role. Exploration and evaluation of Bluetooth features introduced with BT 5.2 to help enable new Sonos user experiences.

Bluetooth software development in C and C++ for Sonos Players. Includes BT application, stack, driver and firmware development. Co-designed and implemented a new Bluetooth application and abstraction layer to support different radios and Bluetooth stacks that launched with Sonos Roam. Worked with radio vendors to debug and implement fixes for BT/WiFi coexistence issues leading to negative user experiences.

Designed and developed test automation and tools in Python and C to improve nightly test coverage and reduce manual test load where reasonable. Developed, maintained and executed test plans to verify lower level Sonos Player software (Sonos HAL, linux kernel, bootloader, drivers and firmware).
