11/94-7/03: DOBLE ENGINEERING CO., Watertown, MA
Senior Software Engineer
Programmed in Microsoft Visual C++ using the Microsoft SDK. Used all of the releases from MSVC 1.0 through and
including MSVC 6.0; RougeWave was used throughout all of those Protest releases. Also used Visual C++ for Windows
CE on various Windows CE platforms with the appropriate platform SDKs. The Windows CE platforms were used to
control the F6X from various smaller devices (including handhelds). Made extensive use of MFC, OOA, OOD, OOP, and
design patterns.
Doble’s products are primarily power system simulators. These generate voltages, currents, frequencies, and phase
shifts of phases of EMF waveforms that are either described directly in the test (for steady states as well as linear and
binary searches) or to replay transient waveforms that were previously captured (during a transient event (such as a
lightning strike)) or specified through a waveform editor. The waveforms are used to test relays and circuit breakers and
determine their compliance to manufacturers operating specification as well as configuration operability.
Had to refactor Protest many times due to changing hardware (both PC platforms and Doble instruments (new
instruments had to be supported to run the older tests even though the communications protocols were completely
different while maintaining the support for the older instrument sets), software (from DOS through releases of Windows
from Win95 to XP; FOXPRO to SYBASE; various releases of Crystal reports; various releases of Rogue Wave; et al), and
market conditions (power utilities have been undergoing their own refactoring efforts as power generation, distribution,
delivery, and maintenance have been divided; the business interfaces to the participants in the power grid have changed
radically as a result).
The port of the Protest functionality from the original DOS platform to Windows involved both UI and database redesign,
but core functionality had to be preserved. Protest 3 (the last DOS based product) was written in FOXPRO. The new
Protest was based on SYBASE and written in C++. The transient functionality was incorporated into Protest from a DOS
product written in C; it was refactored into C++ to support waveform generation on both the F6X and the F2K Doble
platforms (the legacy product only supported the F2K).
Did pre-sales support, post-sales support, customer support, and customer training.
Developed special communications drivers for Hydro Quebec resulting in a $5 million sale.
Trained engineers from BPA (Bonneville Power Administration) in the use of my APIs. Ported the API set to Windows CE
for BPA’s use. This resulted in a $6 million sale.

Designed and presented a course to customers who wanted to build their own macros using the F6X APIs (this course
was presented in Baltimore in the Fall of 2002 at the Doble User Conference).
Helped a summer intern port Mirror (in Perl) from a LINUX platform to an NT platform.
Designed and developed communications and protocol DLLs for interfacing PC-based UIs for Win32 environments (XP
through Win95) with embedded systems for instruments made by Doble to test relays and other power systems
equipment. Other of the DLLs developed implement macro functionality on top of the communications DLLs. All the DLLs
are written in C++ for MSVC; the last release of MSVC I used for this was Visual C++ 6.0.
Used object oriented design and object oriented programming techniques extensively.
The F6X protocol allows client applications (some written at Doble, some written by third parties) to define deterministic
finite state machines that describe power system simulations.
The transport macro classes designed for the F6X protocol follow a variation of the Envelope/Letter paradigm where in the
F6XTransportMacro class is both the envelope class and the base class for all derived letters allowing for recursive
polymorphism (based this design on Coplien’s polymorphic number class, though a class factory paradigm was used
instead of a virtual constructor paradigm for construction of the representations). This resulted in a design that was both
divisible (was able to take on additional staff and improve time to market) and scalable (didn’t have to develop all of the
classes for the project to be demonstrable or shippable), thus allowing defiance of two of Brook’s laws (see The Mythical
Man-month).
Designed and developed a set of APIs that give access to the objects in the DLL to third party developers. Also
supported our third party developers domestically and internationally. They use the third party APIs from both VB and
C++.
Instrumented the F6X and F2K DLLs in such a way that communications sessions may be captured (by activating a back
door). These can be used both for static diagnostic purposes and as input to the applications that generated them.
Replay allows debugging of the UI without the need for a physical instrument or the equipment that was being tested by
the instrument. That was particularly important when there were very few real F6Xs in existence. It is also important
when the equipment necessary to show a problem is not available to R&D (such as customer relays, circuit breakers, or
power system stabilizers).
The upper layers (both of the DLL and the application that is calling it) are unaware that they are not connected to a real
instrument. This allowed the Protest application that controlled F6Xs to be ready when the F6Xs were ready to be sold
broadly. It also allows our third party developers in India to debug their applications without having to have access to an
F6X all the time.
Was an in-house consultant to the engineering department on all things related to C/C++.
