RKT Engineering, Inc. / RKT Technologies, Inc., Londonderry, NH
September 1977 to Present

In 35 years as Owner and President of RKT Engineering, Inc. (a Massachusetts corporation) and its successor corporation RKT Technologies, Inc. (a New Hampshire corporation), I have provided hardware and software design consulting and technical services to a number of companies in the Greater Boston and Southern New Hampshire area and elsewhere in the Eastern and Central USA. Highlights in approximate reverse chronological order (except where indicated):

  • (2015)  Performed an independent code review and provided corrections for faults found in software for a class 2, major level-of-concern, critical-life-support medical device.
    • Performed a comprehensive independent software review consisting of design review, code inspection, and static and dynamic code analysis.
    • Advised and provided corrections for literally thousands of issues found in more than 200,000 lines of code proving once again that this type of review and verification needs to be done on an ongoing basis during all phases of development, and not postponed to the end.
    • Identified some hardware issues that manifested themselves as software bugs, and provided recommendations for correction.
    • Performed an analysis of USB 2.0 traffic flow and interface to USB 2.0 devices, using a USB 2.0 protocol analyzer. Provided the protocol analyzer used in making this analysis.
    • Software is in C++ on the QNX RTOS and Momentics IDE, making extensive use of C++ templates. Hardware uses multiple processors (TI iMX-53, 2x68332, 8051) communicating with one another via serial, USB, and SPI bus.
    • Guided the migration of the project to Subversion (revision control system) and Bugzilla (bug / action item tracking). Hosted, configured, administered, and maintained the projects Subversion and Bugzilla servers.
  • (2015)  Organized and served as co-producer and co-moderator for a public forum and presentation on how to apply Agile software development to medical devices using AAMI TIR-45:2012, presented by the Medical Development Group of Boston (www.mdgboston.org). My responsibilities included recruiting speakers, researching subject matter, identifying the target audience, producing advertising materials, and monitoring progress so that everything was completed on time.
  • (2014 - 2015)  Providing software regulatory and independent-review consulting services on class 2 / 510(k) and class 3 / PMA medical device products.
  • (2009 - 2012)  Developed a user interface and served as a software and regulatory consultant and software team leader for a class 3 medical device that delivers RF energy to the patient.  Recruited, and provided leadership and supervision to, a team of 3 senior software engineers and 1 senior software quality assurance engineer.  Software development was in C++ for MicroC/OS-II, and design used Unified Modeling Language on Sparx Systems Enterprise Architect.  Device made it through FDA PMA Supplement approval in half the normal time.
  • (2008 - 2009) Implemented a master-slave communications system on an infusion pump for veterinary use; software development in C for FreeRTOS. Provided regulatory consulting services to that client as they evaluated whether to certify the infusion pump for human use.
  • (2008) Served as software quality assurance and regulatory consultant for a collaboration among a number of university research centers to develop an artificial pancreas for Type 2 diabetes sufferers.
  • (2007 – 2008) Performed a full requirements analysis and top-level design for a digital communications system for Boeing 757 airliners and freighters being developed to FAA DO-178B standards, using C++ on MicroC/OS-II operating system. Client retained my services in doing the requirements analysis while they searched for a qualified permanent employee to continue the development.
  • (2007 – 2008) Served as independent software quality assurance analyst for a new type of ice cream vending machine; system used a Linux-based multi-tasking software package driving custom hardware to dispense individual servings of ice cream of the customer’s choice of flavors and mix-ins.
  • (2007) Performed a major software rehabilitation and refactoring project on a complex machine vision system whose software documentation has become obsolete, and the C++ software has become unmaintainable.
  • (2005 – 2006) Served as senior software engineer for a multi-device, multi-node Voice over IP communications network implemented on embedded Linux in C++.
  • (2004 – 2005) Designed and implemented the software for a feasibility prototype of a SCADA (Supervisory Control And Data Acquisition) system to monitor and control the operation of appliances in a shipboard galley for the US Navy. System was implemented using the Iconics Genesis32 SCADA platform and Visual Basic code. Also served as advisor for system- and hardware-related issues.
  • (2004) Hired to perform a major system upgrade to a Night Targeting System Upgrade Kit for helicopter flight simulators that I had developed in 1995-1997. Original project was developed to run across three separate processors, with two of the three processors executing single tasks. This year’s upgrade involved moving to a new, faster CPU with a single processor. This required an extensive restructuring of the system software to run in multiple tasks (a total of 19 prioritized tasks) on VxWorks 5.5.1 using Tornado 2.2.1 as IDE.

    As part of this project, I designed and wrote a multi-tasking data simulator on Microsoft Visual Studio / Visual C++, to send and receive formatted data concurrently across 6 serial ports to the target system. This tool involved creating several dialog boxes to configure the outgoing messages and specify the expected configuration of the incoming messages.

  • (2003 – 2004) Served as Principal Software QA Engineer for a new type of endoscope. Duties included making sure that the software development was in full conformance to the FDA Quality System Regulation / 21 CFR 820, ANSI / AAMI SW-68, ISO 14971, 21 CFR 11, and each of the stakeholders’ internal Standard Operating Procedures. Also served for a time as acting Software Project Engineer for the project, with duties that included managing the activities of a group of off-site software developers, and assisting in defining the job description and qualifying a permanent employee to take over that role.
  • (2001 – 2003) Software architect and key software developer for a navigational system for installation on oceangoing ships. Also served as mentor to other software engineers in the areas of C++, VxWorks, Tornado, and Unified Modeling Language (UML).
    • System provides a central redundant fault-tolerant computer that takes inputs from Inertial Navigation Systems (INS), Global Positioning Systems (GPS), depth sounder, magnetic compass, speed-through-water sensor, and redundant weather sensors, and outputs information to shipboard displays and other shipboard systems.
    • Central computer provides services including Dead Reckoning capability so that the ship’s position could be estimated in case of failure of the INS and GPS.
    • Central computer consists of two PowerPC processors in a CompactPCI chassis.
    • Designed central computer software using UML on Rhapsody Modeler with implementation in C++ on VxWorks 5.4 and Tornado 2.1.
    • Designed and implemented a graphical display on Linux / Xfree86 using a TCP/IP network connection to display the real-time value of variables in the VxWorks target system software, for use in debugging and verification.
    • Provided code modification and code review services and assisted in testing and debugging of the Graphical User Interface (GUI) for this system, which was implemented on a ruggedized PC using Microsoft Visual C++.
  • (2000 – 2001) Key software developer for a Voice Over IP (VoIP) test system for use in testing and validating VoIP gateways.
    • Platform was PowerPC on CompactPCI and VxWorks with development under Tornado 2 in C and C++ using Object Oriented Analysis, Design, and Programming (OOA/D/P) including UML and Use Cases.
    • Designed and implemented some simulation and test software on Linux / Xfree86.
    • Served as mentor and instructor to other software engineers in the areas of VxWorks and real time programming.
    • Served for a time as acting Principal Software Engineer / Technical Lead for this project while the client went about the process of hiring someone on a permanent basis to assume that role.
