Extensive experience in developing real-time and embedded firmware. I am especially adept at taking on code late in the development process. Experience includes:

• Developed and debugged code on Bluetooth chips (Classic and BLE) by CSR, Nordic, and STM32. These ran software like CSR OS, FreeRTOS, ThreadX, and WICED.
• Integrated STM32 and ThreadX code into drivers for serial ports and external QSPI flash.
• Analyzed and improved FW download performance of Nordic IoT system. Data path was C# program to ADROCOM I2C interface to BLE dongle to BLE receiver to I2C.
• Wrote C# code for a data collection system using VISA instrument control.
• Designed OTA system for STM32-based product, and implemented the bootloader part of the system.
• Assisting HW engineers in HW/FW architecture.
• Developed FW for Cirrus audio chips (CS74L90, CS48LV41F, CS35L41) and their development tools (WISCE, SoundClear).
• Developed and debugged HW with SPI, I2S, TDM, AC2, USB interfaces.
• Developed code for PSA and hearing aids, both internal FW and external SW.
• Integrated systems with Amazon AWS software.
• USB3 driver investigation for the Cypress FX3 chip.
• Embedded Linux development including Yocto, CLSIC drivers, ALSA audio applications, and general system design/integration.
• HW/FM designs with Technexion NXP modules.
