Corp-to-corp contracts, usually off-site. rate depends upon
cool-factor and location. CTH and W2 possible for something at 11 on a scale of 10.
I love writing software, it is my hobby and profession, and like working with
either web 2.0 or scientific applications in particular. Funding has dried up
after six very intense and enjoyable years at Sandia National Labs, and even
worse, I am now addicted to Ruby on Rails and JavaScript. I am looking for
anything RoR, or anything on the front-end or scientific/mathematical in...
Java, JavaScript, or even C. I have a very strong 'Get Things Done' work ethic
and have been lucky enough to work for organizations that have the same approach.

of the Mica graphics framework (see below) and Cadabra application framework.
This application provides novel techniques for editing networks as well as a
fully modern user interface (including direct-manipulation graphics editors,
tooltips, context-sensitive help, automatic periodic backup and recovery,
drag-and-drop, right-button menus, editable drag-and-droppable treelist widgets,

Raynet engineering team. The application was successfully deployed in many
European countries.
Consultant (off-site) - @ SunSoft, Colorado Springs, CO
3/94 - 6/94
Prototyped two applications (Online DiskSuite, HATool). One prototype contained
a dynamic flowchart from which windows were launched. The other prototype
included a constrained, interactive treemap editor with extensive design rule
checking. These were written (re)using a C++ framework and a C++ graphics editor
object on Motif and X Windows.
Consultant (off-site) - @ Ericsson Raynet, Menlo Park,
CA 11/92 - 11/93
As technical lead, designed a layered, object-oriented system architecture and
implemented the framework and application layer for RIDES, a large
telecommunications operations support system (OSS) targeting the international
market. This framework and application layer contains over 120 large
internationalized windows, 3 graphics editors, and over 200,000 lines of C++ and
exists between the Motif widgets designed and generated by the TeleUSE GUI
builder and a custom interface to the Ingres RDBMS.
Consultant (off-site) - @ Innovative Research, Denver,
CO 8/91 - 11/92
Designed and co-wrote an object-oriented graphics application to interactively
describe, visualize and simulate a computer network for capacity planning and
analysis. This included a direct-manipulation graphical editor and a Motif GUI
as the front end and the Sybase RDBMS as the back end and was written in C++.
Consultant (off-site) - @ Loral Data Systems, Sarasota,
FL 12/90 - 7/91

(1990) Designed and implemented PGL, a portable high-level 2D vector graphics
library, toolkit and GUI builder in `C' which allows applications to run
unchanged on top of SunView, the X Window System, and DOS PCs. (1992) Rewrote
graphics library using C++ (EditorObject) which encapsulates all the
machinations that direct-manipulation graphics editors require. (1993) Added a
configurable framework and associated `framework meta language' layered on top
of the EditorObject (VisualADE). (1996) Wrote a Java command-line debugger
(Zap). Re-designed and implemented the EditorObject (now called the Mica
Graphics Framework, a pre-Swing full-featured OO UI toolkit with integral
support for 2D CAD graphics) and VisualADE (now called Cadabra) in Java. (2008)
CoderToys using humor driven development methodology to achieve several hundred
orders of magnitude gains in productivity.
Developed many system utilities, DOS enhancements, business and programmer aids.
Design goals were compactness, speed, utility, and simplicity. Terminate and
stay resident (TSR) PC utilities included: hex calculator, clock, speedkey,
scroll-back, screen-saver, command line editor, ramdisk, etc. Other tools were
delete/copy directory tree, findfile, grep, diff, cmp, touch, dump, 68000
