Software consulting for embedded systems development and embedded graphics systems for defense and aerospace industry.

Embedded firmware for specialized sensors.

QA and Release Engineer on the Yocto project.

Embedded firmware and software for solar power inverters.* Software lead, architect and designer for new data monitoring solution based on an Embedded Linux ARM platform. Wrote the software requirements specification, developed system architecture, researched and recommended an embedded database solution. Developed key portions of the software, including Modbus master and slave interfaces, Utility Interactive Controls (UIC), based on IEC 61850-90-7, DSP translation layer to provide common interface to multiple power control engines.*  Specify, document, design and develop a solution for communicating between existing DC Subsystem (DCS) microcontroller (STM32F105) and new smart Combiner PV Tie box. Proposed semi-custom protocol based on Automotive LIN standard. Solution on STM32F105 required a software UART implementation for sending and receiving data due to the limitation of no hardware changes to DCS PCB

Embedded firmware and software for solar power inverters.

Firmware and hardware design for wrist worn activity monitors used in sleep research.* System architect for the digital subsystem of the new Actiwatch® 2 and Actiwatch® Spectrum products. Architected, designed, wrote, and documented the firmware for the main and lcd controllers for the new Actiwatch loggers. Designed and documented a serial protocol for use between the loggers and the PC software. Wrote component specification documents (CSSs) and updated bills of materials in SAP. Wrote and coordinating the writing and signing of various quality documents required as part of the new product development process. Learned SAP for the Engineer role (DIRs, BOMs, ECRs). Assisted in troubleshooting production line startup problems, including debugging the production test software and investigating device failures. Listed as co-inventor on patent application for this product. Participated in FDA audit and multiple vendor audits.* Enhanced Actiwatch® 2/Spectrum firmware to support Actical-like measurements and scoring (ala Actiwatch® Score).* Initial design of Actical Fast hardware to add larger (flash) memory and newer microcontroller.

Firmware and digital hardware design for wrist worn activity monitors.

Developed embedded software for communications test equipment, including metallic and optical TDRs, serial communications network analyzers and microwave network analyzer.
