Samples of Work







Type of work:


W-2 Full Time





  I am a seasoned Consultant/Senior Software Engineer/Architect/Developer focused on solutions that work. I use a problem reduction algorithm; which breaks down each major problem into a group of smaller manageable problems. Once a solution is found for each of these smaller problems, then, the result, is often a workable (albeit, maybe not perfect) solution to the overall problem. Refinements can then be made to perfect the overall solution.


My experience covers implementing solutions for projects, products and software on the following platforms as listed below and in the following environments:


       Platforms: Mainframes, Minicomputers, PCs, Embedded Systems, etc...; Environments: RTOS on embedded systems, TSO/CICS/JPL on mainframes, Linux/Ubuntu on PCs, AIX/UNIX on minicomputers, Windows (all the way back to DOS) on both clients and servers.


       Development Environments included: Assembly, CUDA, RTOS, UNIX (Solaris, HP-UX and AIX), Linux variants (e.g.: RedHat / Ubuntu / CentOS), Windows (e.g.: Windows 10, Windows 7 Professional, Windows Server 2008, Windows XP, Windows Server 2003, Windows 2000 Professional, Windows NT and Windows 95) and on Real Time Operating System (e.g.: Integrity RTOS from Green Hills).


     Networks software development: TCP/IP & UDP socket layer SW development, installation/maintenance of networks, familiar with routers, modems, hubs & network wiring, etc...

  Over the last 1/3 of a century, in the consulting/technology business, I constantly see projects that have gone off into the weeds and yet thousands of dollars keep getting poured into these, without correcting the underlying real problems, with budgets and schedule going off track. However, by ensuring that these projects are right-sided, or better yet, are started correctly, in the first place, and are built on the right technologies/foundation, then their long term maintainability is made easier and the longevity of the agencies/companies that depend on them, have a much better probability of success, being effective and profitable.

  My experience includes working on mission critical applications for fortune 500 companies, State government departments as well as Federal government agencies in many locations within the continental USA. On the detailed resume my proven track record is shows which skill-set(s)/technology(s) were used on what project and where the work was performed.


  My Windows, Mainframe, UNIX, Linux, embedded RTOS and software architecture/development experience includes HLLAPI, tier software layers of deployed systems, event-driven multi-threaded applications, distributed applications (e.g.: Client/Server between mainframe, minicomputers & PCs) and use of design patterns in my OO (Object Oriented) software architectures. And yes, I know the difference between a thread, a process and task spaces on a RTOS (i.e.: Real Time Operating System).

  I am experienced with low-level network communications, for both TCP/IP and UDP sockets and custom (i.e.: customer specified) protocols, including resolving/handling issues of partial message reception/collection and parsing these byte stream messages. The reason I favor Design Patterns in my OO (Object Oriented) designs is that these facilitate reuse of “known-good”/”time-tested” sub-architectures and promotes the reuse of these "known-good" solutions as implemented in related (templated, where applicable) code.

Projects that I have worked on were in the following technologies/market-sectors:
   1. Airline ticketing
   2. Artificial intelligence/CUDA
   3. Automated job routing and control
   4. Computer system control (via C/C++ on mainframes, UNIX, Linux, Windows & embedded systems)
   5. Federal and State government data processing
   6. Database administration, tweaking & maintenance
   7. Fiber optic provisioning
   8. Gas/petroleum decomposition automated analysis
   9. Medical procedures and equipment (e.g.: heart monitoring, hemodialysis, etc...)
  10. Oil and gas cross continental system control/monitoring
  11. Oil rig early warning systems (as located in the oceans)
  12. Particulate (white room) studies
  13. Petroleum/oil rigs equipment configuration and costing analysis
  14. Staged robotic controlled assembly line control
  15. Robotic high speed printing control systems
  16. Robotic medication distribution systems
  17. Satellite control systems
  18. Server farm control and automated intra-actions
  19. Stock market trading algorithms and market technical and fundamental analysis
  20. Financial institutions internal workings
  21. Package/UPS delivery system tracking and billing internals
  22. Very heavy equipment (locomotive/train) transportation controls
  23. Very large computer performance tweaking and system analysis

1)       ‘PGC5000’ – a Gas Chromatograph Analyzer. The PGC5000 Analyzer was implemented on an embedded platform running a RTOS (Real Time Operating System) on an SBC that has a local and remote GUI (Graphical User Interfaces: LUI and RUI) for displaying Gas Chromatographs in real-time. The ‘Master Controller’ section of the PGC5000 was designed using objected oriented technology and implemented via ANSI C++. My portion of the architecture and development of the PGC5000 was the two mission critical tasks named, ACE (Analysis Control Engine – for schedule management of Analyses being sent to the Oven(s)) and APE (Analysis Process Engine – for data capture, collation and assembly of the binary Analysis Reports generated).

    Click to see => Product Of Year Award


2)       ‘STAR Server’– A data historian, which captures streamed (TCP/IP) and packet (UDP) data from a maximum of 254 Gas Chromatograph analyzers (e.g.: PGC5000(s), PGC2000(s), RVP(s) (e.g.: Reid Vapor Pressure) and Multi-Wave Analyzers) and one barometric pressure meter. Using ‘Enterprise Architect Professional’ as the UML design tool, I performed all architecture/design tasks for this Object Oriented, multi-threaded, multi-socket, multi-pipe, database connected (via C++ calls to SQL stored procedures) data historian. Technical specifications were captured in the EA Model (e.g.: in the UML (e.g.: Sequence, Associative and Inheritance) diagrams and related URL links. Implemented the ‘STAR Server’ as a Windows Service on a 64-bit Windows 2008 platform. The ‘STAR Server’ both saves and retrieves BLOB (Binary Large Object) data and trend data points to/from the MS-SQL 2008 partitioned database (as stored on a RAID array). My design also included support for future third party OPC devices/analyzers. Performed all tasks related to the Object Oriented design/architecture (OOD/OOA) and over 97% of the coding effort for the C++ code and SQL stored procedures for the ‘STAR Server’ (e.g.: with the exceptions being for one Legacy DLL written by Jeff Ross (co-worker), the ‘Reprocessing’ DLL (a PGC5000 related task) and some SQL stored procedures as written by Mike Crowder (also a co-worker).) I setup the Visual Studio 2012 solution for the ‘STAR Server’ to be both 64-bit and 32-bit compile-able, based on the user’s VS2012 configuration management settings, with all binaries copied to just one sub-directory as each project in the solution (for each of the DLLs) completed its build step, thus simplifying deployment for the build manager. Also, setup the Visual Studio 2012 solution for the ‘STAR Server’ test environment to perform unit level testing.

Test Environment (Part A)


Test Environment (Part B)





Technologies used: ANSI C++ (used for both projects), SQL, Window local pipes (used for low-level client/server communications), Socket level development (for both TCP/IP and UDP network connectivity), UML, RDMS, RTOS (Green Hills Multi/Integrity), BLOB data handling/parsing (to/from database storage/retrieval), Client/Server API development, multi-threaded (on Server)/multi-task (on RTOS) development.


Tools used:  Microsoft Visual Studio (i.e.: VS2012, VS2010, VS2008 and VS 6.0), Visual Source Safe, MS-SQL Server 2008, Integrity/RTOS, Enterprise Architect Professional (UML Modeler), EDGE (UML) Diagrammer, Tracker (PRC system), MS-Project, MS-EXCEL, MS-WORD, Core-FTP, Software Verify (e.g.: a C++ dynamic code analysis tool (e.g.: performs memory leak detection, thread analysis, memory stomp analysis etc…)), VPN, XML Viewer, DocuShare, WinDiff, GoToMeeting, etc…


Platforms: RTOS (‘Integrity’ from Green Hills, Inc), Windows Server 2008 (used as the ‘STAR’ server), with Windows 7 and Windows XP (used for the UML design and C++/SQL development platform(s))



STAR Server (Windows Service):

Ø       Performed all tasks for the STAR Server, which runs as a Microsoft windows service (e.g.: Objected Oriented Architecture/Design, UML diagramming, coding and unit testing)

Ø       Wrote over 100,000 lines of C++ code and MS-SQL code for the ‘STAR Server’

Ø       Performed stream handling for TCP/IP sockets and message assembly for UDP packets

Ø       Captured messages from TCP/IP and UDP sockets, parsing these and storing this Trend data and BLOB data into MS-SQL 2008 partitioned database (as setup on RAID storage)

Ø       Specified, designed, documented and distributed the ‘STAR’ Client/Server API to the team working on the ‘STAR’ client; Said specification defined all low-lever data transfer structures for PIPE communications between the STAR Client(s) and STAR Server(s).

Ø       Specified, designed, documented and distributed the Legacy API to the team; Said specification defined low-lever data transfer structures and callback functions for data transfer between the ‘STAR’ Server and legacy devices (e.g.: PGC2000 and Multi-Wave devices).

Ø       Performed distributed intelligence testing between PC clients, STAR Server, PGC5000, PGC2000, Multi-Wave Analyzer and RFP (Reid Vapor Pressure) Gas Chromatogram Analyzers (e.g.: performed testing on all aspects of BLOB (e.g.: Binary Large Object) transfer, validation, parsing and importation to MS-SQL database (see below)).



PGC5000 (embedded system):

Ø       Real Time Embedded Software Development - Wrote all the C++ code for the runtime environment modules called ACE for the ‘Analysis Control Engine’ and APE  for the ‘Analysis Processing Engine’ for the PGC5000 (Gas Chromatograph analysis system) shown below, which product won “Product of the Year” in its category and is currently being mass produced and sold all over the world. For details, see also: http://www.abb.com/product/seitp330/a6ccc6def51d04e9c12574b100571ee3.aspx


Ø       Designed the Object Oriented Architecture for both of these mission critical tasks (e.g.: ACE and APE) for this RTOS (Real Time Operating System) embedded product to be elastic in nature (meaning that if a physical dimension changed, which impacted the software specification (e.g.: the number of Ovens, number of Schedules changed, etc…) then the software would corresponding adapt, if just two numbers changed (e.g.: one for memory allocation and the other for the dimension that had changed)), thus managing the total cost of software maintenance/ownership and increasing the financial gain over the life to the product as market changes or new requirements impact the embedded system’s design.

Ø       This allowed both ACE and APE, the capability of resizing the infrastructure as needed to execute the gas chromatography analyses in a multi-detector, multi-schedule and multi-oven environment. With this capability, ACE and APE could be quickly restructured to meet changing market needs by simply changing the value for desired dimension. Example: If the PGC5000 needs to handle more Schedules, only two numbers needed to be changed for that dimension and the corresponding memory allocation to enlarge the software infrastructure handling capabilities, such that upon recompilation it would then support that new requirement.

Ø       Implemented this OOA/OOD in C++ code (as captured in my UML diagrams)

Ø       Designed both ACE and APE to support eight different elastic dimensions for the number of: Schedules, Ovens, TCFs (Time Coded Functions), Gas Chromatograph Detectors, Gas Components, Scripts, TCF Methods, Analyses and Schedule Elements (each being a duple of Analysis and Stream).

Ø       Wrote the ‘Analysis Validator’ to ensure that all Analyses are correctly composed.

Ø       Wrote a code generator that produced the C++ code that provided the object oriented infrastructure/framework for both ACE and APE, thus ensuring code uniformity, quality and at the same time eliminating the bulk of development time typically needed when debugging large projects. The number of code lines written and generated for both ACE and APE using this technique was over 90,000 lines of C++ code, which then was deployed in this RTOS embedded project, the PGC5000, which code when executing used less than 2% of the available CPU, leaving 98% CPU for other tasks in the PGC5000.

Ø       Designed and implemented each schedule to run in multiple ovens simultaneously with other schedules, with each schedule capable of handling its own analyses in its Schedule Element queue while at the same time, all the other schedules do likewise.

Ø       Incorporated polymorphic behavior in APE for handling the variant calculations of: validation, calibration and standard report types.

Ø       Designed and implement low-level translational services for the decomposition of analyses to enable execution in any or all of the connected ovens.

Ø       Performed P2P (Peer to Peer) bandwidth utilization testing across Ethernet between the PGC5000 embedded systems (e.g.: performed TCP/IP stack efficiency testing)

Ø       Generated calibration, validation and standard analysis reports, develop code to coordinate the assembly of the associated chromatograph files and the propagation of the alarm analysis report files, should any of the analysis’s alarm indicators occur.

Ø       Calculated response factors (low & high), gas component concentrations, pending response factors, etc…

Ø       Built ACE and APE as event driven software, thus minimizing CPU utilization.

Ø       Included script processing support for both event-driven and end-of-analysis scripts.

Ø       Gave ACE and APE the capability of processing very large and complex analyses as well as simple analyses in a multi-detector, multi-oven and multi-schedule operating environment.

Ø       Integrated automatic reclaiming/recycling of memory resources in both ACE and APE to maintain real-time software stability and robustness, thereby eliminating costly kernel calls for memory allocation and de-allocation, and thus eliminate needless CPU cycle usage.

Ø       Incorporated a schedule ‘state machine’ in ACE for handling random GUI requests for schedule state changes using an elastic sparse matrix to provide this dynamic functionality

This SCADA related, legacy Windows Visual C++ GUI application, was originally developed in the USA and then off-shored. My task was to stabilize the MMW software’s build environment and to fix a number of its bugs. Cleaned up the builds for the MMW software for version 1.5, 2.0 and 2.1, so that it could now be built using only the IDE (Integrated Development Environment) instead of the DOS batch programs and further enhanced the build environment by adding the project interdependencies within the workspace so that the sequence of any GUI initiated build would always progress from the top down (thus eliminating any need for multiple build runs). Further, to I setup the test environments and configured a number of DSNs to support the low-level ODBC calls as the MMW software executed the embedded SQL. Fixed embedded SQL formatting issues as these related to each database type as configured behind each DSN (Data Source Name).


The size of codebase could barely fit on one CD (650 MB). The software had a number of bugs, some simple, many difficult. As is usual with large legacy projects, like this one, there is no documentation, so to fix the bugs, I used logical progression, methodically tracking down each bug and with much endurance, I stayed the course, until the project was enhanced to a point where the client was satisfied and it was ready for him to present my fixes/enhancements to the user community/ group, to secure more R&D funds to sustain the longevity of the project.

: Code base migration of GEMS (Gas Environment Management System) from UNIX to Windows 2003 Server and Windows 2000


Migrated a gas pipeline Nominations system (a mission critical application called GEMS) from HP UNIX to Windows XP for deployment on Windows 2003 Server at an annual cost savings of $250,000. Converted the UNIX ANSI C software/(code base) to Microsoft C/C++ and constructed the complete Microsoft Visual C/C++ development environment for said code base. Used .Net development tools for compilation of COM components.


Performed system analysis and design. Wrote programs that migrated the code base of over 120,000 source file versions from HP UNIX platform(s) to Windows XP with little or no impact to users and production-support developers and while maintaining compliance with the legislated law of the Sarbanes-Oxley Act.


Wrote all the software needed to decompose the UNIX source control management system called 'SCCS' and wrote all the software to recompose all versions of this code base into PVCS (the Windows source control management system, which included automatic collation of versions). The program when executed ran on UNIX in the decomposition phase for about 70 hours and in the re-composition/importation phase for about 10 hours.


Migrated the complete GEMS code base from the UNIX-based SCCS to Windows-based PVCS source code management system.


Wrote and generated UNIX and AWK scripts to automate SCCS source code extraction.


Wrote Visual Basic (VBA) code that automatically edited, converted and fixed the 'C' source code to eliminate programmatic errors due to memory stomping, memory leaks and non-initialized variables for 376 files of the GEMS code base.


Wrote C++ programs to integrate the UNIX ported ‘C’ code base into the new development environment of Windows XP and the new production environment of Windows 2003. This effort represented the automated editing of about 1.1 million lines of GEMS source code, based on 376 source files, with an average size of about 3000 lines of code each. This process took under 60 seconds to perform the automated edits for all code line within each ‘C’ source file.


Wrote the code that generated the Visual C++ development environment (the VC++ IDE workspaces and projects) for the GEMS ‘C’ code base conversion efforts. Yes, I actually generated the development environment from meta data as held in a database table, which was imported from UNIX source code versioning information as embedded in the actual UNIX executable binaries and then used that extracted information to build the development environment on the platform of Window XP that enabled the team to complete the GEMS code base conversion effort from UNIX to Window XP.

Imported UNIX ‘C’ source code meta data into MS-SQL 2000 for preprocessor directives’ vocabulary reduction.  Analyzed said meta data to consolidate multiply defined preprocessor directives in the code base to facilitate the massive code base cleanup effort.


Performed delta merges from production system code base to our GEMS conversion code base, so that any change on the UNIX production side would be reflected on the Windows side, while the UNIX code base continued   to be enhanced during our conversions efforts. This was carried out until the UNIX code base ceased to be enhanced as we neared the cut over to the new Window Server 2003 production system.


Acted as a primary technical lead, providing technical training and guidance to junior level developers and reduced complex technical issues into simple terms to relate to less technical, non-technical team and management team members.


Environment: Windows XP, Windows Server 2003, HP-UNIX, SQL Server 2000, Sybase 6, Visual Studio .NET, Visual Studio 6.0, SQL, AWK, SFU, PVCS, PCLI, SCCS, C/C++


Skills used: C++, STL, multi-platform ‘C’ code porting  and auto-FTPing between HP-UX and Windows XP and  platforms, SQL  coding/queries, UNIX ’C’ and Win32 development tools, Unix Scripting; Personnel skills: worked closely with other team members and management to determine project specifications and architecture/design.

Wrote several applications, the most notable was the JEOR project. Technologies/Skills used: Objected Oriented Design (UML diagramming via Rational XDE), C++, UNIX (Solaris), Sybase, Perl, SP/SQL. Size: about 35,000 code lines of C++ and UNIX, which I personally wrote and debugged.


Designed, Architected and programmed the object oriented project called the JEOR – (Job-Entry-Output Redirector) system. This system enabled the production support department to submit new applications based on customer requirements as one of the following: a binary, database stored procedure, SQL, UNIX script, perl or java program. And then specify how the output would be transmitted via transmission type specification which could one of the following: email, FTP or ESIGTR (file routing). The routing specification was a user configuration as stored as a database entry.


My JEOR project eliminated the need in the J.P. Morgan D.A.M. (Distributed Application Management) system for individually reconfiguring the UNIX environment on a per application/job basis, thereby elimination much of the overhead associated with each new user request/demand placed on the development team;


Other projects included: writing the divmsgrec program, which was a database table cross comparison reporting program which was written in UNIX (Solaris) and stored procedures written in Sybase SQL for the reconciliation of the internal stock trade messages; Also wrote VSETAF – a reporting program that isolated trades in the Vienna market and generates a report of these by filtering data obtained from the Sybase database;
