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

Projects:
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.

and C++/SQL development platform(s))
Project(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
