WHAT I AM
I have been a Senior Software Engineer highly experienced in software design, development and test (for
details see the Technical Experience Summary section in the Addendum). Today I design and restructure
software for performance, reliability, robustness and maintainability, Existing software has so often been
maintained and extended that it is inefficient and not maintainable. New software is written to impossible
schedules that forces poor coding just to make a deadline. Old or new code that is misshapen needs to
be refactored and blessed anew.
Design and implementation techniques such as Agile are insufficient and, if poorly used, can make things
worse. Prior attempts such as Dijkstra indicated with goto removal or structured programming were
insufficient. It requires the intelligent application of implementation techniques and includes many of the
older attempts techniques.
My experience has lead me to understand many of the problems and how to fix or even keep them from
occurring. My experience ranges from DSPs to super computers, business systems to scientific and
engineering systems, and a wide selection of computer languages.
