Senior Software Engineer
OBJECTIVE:
To obtain a n interesting position where I can utilize my development skills to help a
technologically advanced business succeed. I feel I perform better if I am either very
interested in the type of work, or technically challenged by the work itself.
SUMMARY OF QUALIFICATIONS:
Results-oriented, high-energy, hands-on professional, with a many years of
development experience in a wide range of languages and platforms.
Major strengths include outstanding communication skills, great technical skills, a team
player, real attention to detail, supervisory skills including hiring, termination,
scheduling, training, and other administrative tasks. Thorough knowledge of windows
and linux based development, and able to pick up new technologies and development
software extremely quickly. I can handle multiple tasks with little supervision and always
strive to be on time and under budget. I can develop embedded code for hardware or
write a UI application for Windows. With 30 years of development experience learning
new languages or tools is often just a matter of syntax.

PROFESSIONAL EXPERIENCE:
Daytona Twin Tec LLC
(12/2114 – 03/2020)
Senior Software Engineer
● Updated existing Twin Scan Harley Davidson diagnostic tool firmware with user
requested features using AVR Assembler and Atmel Studio.
● Updated the Windows application associated with the Twin Scan hardware
usingVB6. The application displays the data collected by the Twin Scan device
● Reverse Engineered all necessary CAN bus communication using sniffing tools
and the Ida Pro Disassembler. ISO15765 standard is followed by Harley
Davidson

Retired, living on the beach and having fun
(12/2014 – 11/2018)
My hobbies included long range wifi transmission of HD video, fully autonomous flight
controls, developing new drone technology working on several open source platforms.
My biggest involvement in Open Source has been the Autopilot project, a flight
controller running embedded linux.
SCT LLC.
Sanford, Florida
(9/2003 – 11/2014)
1/3 Owner and Technical Lead
SCT provides tuning solutions for domestic vehicles via reflash of the vehicles engine,
transmission, and possibly other computer modules via the OBD-II diagnostic port. In
under 5 years SCT went from a start-up to the industry leader in domestic vehicle
tuning.
● Wrote both firmware and application software for tuning domestic vehicles.
● Reverse engineered vehicle communications and reflash requirements for Ford,
GM, and Dodge/Chrysler. Each used different vehicle buses before switching to
the CAN bus standard around 2005.
● Developed alternate utility programs or bootloaders as needed to enable reading
from, writing too, and erasing vehicle modules. Modules could be Motorola,
Proprietary Ford, Power PC, or Tri-core, and would change every few years.
● Developed firmware to bit bang SCP communications because the only decoder
chip was Ford proprietary, and we could not risk not being able to purchase them
in the future.
● Selected new development tools, languages, operating systems, etc. always

paying close attention to our end customers ease of use. Technologies with
complex installs, lots of support issues, any type of difficulty for an inexperienced
end user was not chosen. Many of our customers were not computer literate so
we made our products as simple as possible to install and upgrade.
Hired new development personel as candidates became available.
Maintained existing applications while developing newer replacements utilizing
new technologies. Application software, originally C++, all became C# .Net
applications. Firmware became C++ and Qt, with some assembly language
routines for speed.
Utilized unit testing to ensure quality in all our products.
Developed a method that allowed new hardware tuning option to be added to a
device without any firmware changes. None of our competitors could do that, and
they still can’t. This really set SCT apart in the tuning industry.
Developed a method for bundling tuning changes into one file that could be
loaded by a customer to change a specific tuneable feature. For example a file
might add 10% more fuel at wide open throttle. All of the necessary changes
could be packaged by an SCT expert and sent to a customer. Another industry
first, and was a huge selling point for our software.
Genrad Inc. / Teradyne, Alpharetta, Georgia
(11/2000 – 9/2003)
Java/JSP Developer for Web based Shop Floor Manager Software
● Developed front end application software using Java, Java Beans, JSP,
JavaScript, and other browser products to create a robust GUI for GenRad’s
Shop Floor Data Management application.
● Developed an application that could run on almost any hardware platform and
browser with no difference in response time or user knowledge.
● Became the companies expert on their previous version of software due to my
familiarity with Unix. I ported their Shop Floor Data Manager application (both
Java and Curses based) to several new Unix hardware platforms, learning all
about endianess and the sizes of common data types in C.
● Designed a new star schema database for the web based product and wrote
data extraction procedures for reporting.
AT&T,
Alpharetta, Georgia
(06/1985 – 8/2000)
System 370 Assembly Language / Cobol Programmer Application Support for
LDS Billing
● Maintained a legacy application written in System 370 Assembly language,
running on IBM mainframe systems.
● Used Cobol to create offline reports.
● Ensured engineering applications had sub 1 second response times, thus the
assembly language.
● Developed Unix based applications, learning C and C++, along with relational
databases and object oriented programming.
