SUMMARY OF EXPERIENCE:
I am a veteran of the IT industry who is a quick learner and who is constantly
interested in new developments in software engineering. My career started
during college, with jobs teaching BASIC programming to high school teachers
and students, working with my professors on research projects and working
in video production. In my last year of study I interned at Capitol Video
as a junior software engineer.
My professional career started at American Systems Corporation,
where I became a valuable member of the technical staff
who contributed to system design and rapid development
projects.. I left American Systems to become a contract
software Engineer. Early assignments where in X Window
System software development. In later jobs, I proved my
adaptability by learning; X25 client/server transaction
processing , QNX serial device driver writing, C++
programming, BEA Tuxedo client server development,
embedded SQL programming, Java, Perl, HTML and
XML.
In 1999 I parlayed my interest in photography to become
a photographer for the American Society of Engineering,
documenting the annual ASCE Presidents trips abroad. Each
year I produce a CDROM of pictures for the members who
take the annual trips abroad.
Currently I am interested in working in the realm
of the Semantic Web, that would be anything involving
RDF, SKOS or OWL
