• Vision Pro Spatial Computer
• Supported the bringup of 5 different hardware development platforms that culminated in the creation of the Vision Pro Spacial Computer. These platforms included pre-silicon, mechanical, and final form-factor builds.
• Supported the development of the sleep/wake feature for Vision Pro. Prototyped and requesting hardware changes to simplify the transition from sleep to wake for the two-SoC design. (M2 and R1 Apple Silicon)Additional.
• Single-handedly brought up firmware for a dual-SoC (nRF52840 and STM32L4) prototyping platform, using ZephyrOS. Brought up a custom BLE interface, including OTA DFU capabilities. Brought up drivers for IMU, haptics.
• Supported the bringup of three additional development and prototyping platforms leveraging STM32L4 and nRF52840 SoCs, using an Apple-internal RTOS. Brought up drivers for motor driver IC, encoder, ambient light sensor.

• Core Meditation Trainer
• Developed all firmware for the Core Meditation Trainer, based on Nordic’s nRF52832, an ARM Cortex-M4 based SoC with integrated Bluetooth Low Energy. Wrote drivers for all components in the system, including IMU, ECG.
• Ported FreeRTOS and wrote all system code from the ground up to be thread aware and highly efficient.
• Developed a method to leverage MIDI over BLE in order to live demo haptic-feedback via PC based Digital Audio Workstation (DAW, such as Logic Pro or Ableton Live) along with audio meditation content. This enabled a.

• RearVision wireless automotive backup camera system
• Provided development support for the Camera Frame, a solar-powered dual-camera system running the ThreadX real-time OS on an Atmel SAMA5 Series, ARM Cortex-A5 based SoC. Proficient with JTAG and debugging with the GDB.
• Led debugging efforts for a third-party custom USB camera module and worked with the vendor to understand and root-cause any open issues. Proficient with the Beagle USB 480 protocol analyzer.
• Implemented an SoC system-clock scaling mechanism that reduced overall system power by 50% during periods of low CPU usage.

• iPod Nano digital music player (4th, 5th, and 6th generation)
• Provided debugging support for an ARM1176JZF-S based system-on-a-chip (SoC) running the RTXC real-time OS. Proficient with the ARM tool-chain and JTAG run-time debugging. Assisted with the debug-ging of power-state.
• Optimized filesystem stack for efficiently accessing audio and video content from NAND-flash based mass storage. Performed real-world filesystem fragmentation analysis to understand the effects on flash translation layer.
• Developed a driver for a touch-screen interface in the RTXC OS environment and integrated it into the applications layer. Wrote an interrupt-driven SPI and UART driver for efficient communication with and debugging of.
• Supported the development of the CE-ATA hard disk drive (HDD) interface driver. Worked with two HDD vendors to integrate and debug 1.8” drives, from initial samples to final production units. Devel- oped firmware.
• Led debugging efforts for three generations of 1.8” PATA HDDs. Coordinated with HDD vendors to reach root-cause on factory reliability test failures. Developed a new factory validation test to catch real-world HDD.

• Falcon III series of software-defined hand-held radios
• Developed firmware for the QNX Neutrino real-time OS. Provided hardware abstraction layer (HAL) support for Motorola’s i.MX1 and i.MX21 32-bit ARM-based SoCs.
• Developed USB 1.1 compliant mass storage and communication port device drivers. Analyzed and de-bugged host-device communications using a CATC USB protocol analyzer.
