I have a wide range of experience in digital engineering and software design. My career has exposed me to products in radio-communications, consumer electronics, telephone call-completion and traffic analysis, and multi-user multi-tasking systems for health care and financial risk-management.  Target platforms ranged from embedded 8 and 16-bit MPUs to DEC minicomputers and Pentium and RISC-based PCs and servers.I have had experience with the internals of multi-user, multi-tasking, realtime event-driven proprietary operating systems.  Through use of SSI, MSI (small scale, medium scale integration) glue-logic, and some LSI (large scale integration) MPU-support devices, I have designed, debugged, and tested digital interface logic for minicomputers, hardwired controllers, and microprocessor systems, in embedded and PC-based applications.  Recent projects have involved higher level languages (though I’ve not had significant exposure to CASE tools), multi-user client-server vestiges from the 1990s, and in this millennium, distributed web applications with RIA characteristics. My experience with both systems internals and applications level design, with a backdrop of my earliest projects in hardware and interfacing give me an extremely wide and deep perspective in the field of automation and information technology.


Embedded / Assembler
Some very early projects   Medelco:  A dedicated, hardwired message switching/order-entry system was to be made more flexible and intelligent through interface to a general purpose computer.  The hardwired system would then take on database attributes and could provide inquiry and reporting functions, ad-hoc and canned, while maintaining its efficient message throughput.  In this very small company, all levels of the project were my direct responsibility and included designing and testing the digital logic of the hardwired controller and the minicomputer bus-resident controller, the device drivers, the executive, and the applications software. Tkno-FEP:  I had sole responsibility for the development of an 8085-based communications front-end processor.  Major aspects of this embedded product were modem-handling, data validation at the UART and frame-levels, and communications with the host which involved the classical data-transfer and control handshake functions. TMS-TE500:  A new communications protocol was to be implemented in an existing embedded MPU product.  I designed (including a suitable test-data/protocol generator), coded, and tested the new software.  Also involved was a new modem controller adapter card which I designed and for which I wrote the drivers.   Chameleon:  I designed digital circuitry for a 68HC11 embedded project, specified the software and functional requirements.  Also selected the switching 7 watt DC-DC converter (CALEX), and the modem (XECOM), and designed all glue and interface logic.
OS/2, Presentation Manager
Older Projects under OS/2 I've designed and coded several multi-threaded OS/2 data collection applications.  Some used commercial data-communications packages.  The central technique I use is a finite-state methodology, table-driven, to identify and parse the input and invoke the appropriate validation suite.    SDC Risk:  An application which accepted stock-trades from Lotus-Signal® and performed the front-end processing for a financial risk management system hosted by OS/2-PM.   Allegro-Sugarland:  I specified and coded a major data-collection subsystem, whose target and development were OS/2.  This multiple communication-port application is the collection node of a LAN-based MIS system which polls data solicited or unsolicited, interactively or in batch, on groups of eight simultaneous asynchronous channels under the control of a communications coprocessor.  It maintains a schedule of polls required on a per site basis, validates the raw data, generates error notification and retries.   SDC: I was technical lead on a migration project to Windows-NT/2ooo from OS/2-PM.  The OS/2 product depended upon an ISAM file manager by dbVista (Raima DataManager).  The only native database manager available to us at that time (pre-release) under Windows was the Microsoft SQL Server, and the development cycle to convert to it was deemed prohibitively long for our initial roll out.  I then conceived of a methodology to utilize named pipes to communicate from the ported PM programs running as native WIN32 applications, to a character-based OS/2 application, running under the NT kernel, which, in effect, functioned as an OS/2 Raima database server running transparently under Windows.  This trick of encapsulating an OS/2 process and thus retaining the original OS/2 database API under Windows enabled us to make our initial roll out, with respectable runtime performance.
Flash AScript, Flash Remoting
I designed and participated in about half of the coding for the browser-based Flash front-end of a large multi-user web application (again, the “Willow” product).  Communication to the ASP.NET server was via “Flash Remoting”, which serialized to standard .NET data objects and which allowed the front end developers to use normal built-in Flash data and communications classes. This involved heavy dependency on .NET’s XML properties and the Dataset class.  I took over the final development and all the maintenance of the server-side code as well.
One non-trivial project   Pre-Willow:  I designed, coded, and implemented a series of Java browser applets as a prototype / proof-of-concept in preparation for the “Willow” product.  This also involved the appropriate server-side code (C++/MFC) which instantiated a service socket and server thread for every incoming connection request.  The IDE was NetBeans.
My major C# / .NET Project   Willow Project:  For the same client (see “CNAMS Product” in the C++ section) in a team development (as team leader), I recently finished a web based design (ASP.NET, Flash Remoting) which collects streams of SS7 link-loading records from up to forty-eight remote data probes (the client’s bread-and-butter dedicated telecom collection device) and presents the data graphically in near-realtime, saves the data for histogram and archival purposes, and applies realtime thresholds which generate alerts of various types.  This is the “Willow” project referred to in some of the sidebar examples.
MFC (Microsoft Foundation Classes)
(MFC projects are highlighted above in the C/C++ section)
Some C++/MFC Projects   FEP Project:  I performed the major design and coding for a new PDP-11 based data-collection front-end subsystem for an existing telephone traffic reporting system.  Initially the system dialed up remote sites on various collection schedules and intervals.   Printing Press: I designed a Windows server application which controls ink delivery to newspaper printing presses.  Multiple nodes are used in a TCP/IP based LAN, and the processes communicate via a socket interface.  Embedded MPUs (68HC16) which control digital ink pumps are multi-dropped from the Win32 systems and form secondary LANs on a proprietary protocol.  I designed and coded the class library (atop MFC), wrote all of the user interface code and much of the communications code. CNAMS Product: Most of my recent experience has been team-based, but as a solo developer, I designed a Windows-XP based system for a client who provides telephone call-collection systems to utility companies and regional/long distance carriers.  This system collects data from streams transported over proprietary protocols or TCP/IP sockets, and ultimately inserts reduced data records into an Oracle database.  Installed systems typically handle 70 to 100 million calls per day, while performing realtime analysis and record merging in realtime.  I paid careful attention to software reuse and extensibility in this design.  Performance was an issue, and great dependence on multithreading yielded a design with excellent throughput characteristics.

"...He has exhibited strength through a steady and well-organised approach to his tasks.  His code (C under OS/2 with P.M.) is innovative and of high quality ... A finite-state driven data reduction thread he wrote has performed well and proven to be very maintainable, mainly via table entry modification. Particularly innovative was his use of macros in generating the state-table."
