Dear Sir or Madam

I'm looking for software consulting work. If you can't hire me, you could still
help me out by forwarding this message to your colleagues.

I have seventeen years experience as a developer, with the last seven years
spent full-time running my own business, GoingWare Inc., as a consultant. I have
been a Senior Software Engineer at three companies, and Product Development
Manager at another.

I earn my living serving the software development needs of software publishers,
financial firms, website operators, and device manufacturers.

You can discover what my business has to offer at and
find my resume at

I have my own office equipped with phone, fax and cable modem. I have computers
and software for most development tasks (Mac, Windows or Linux).

My business number is (831) 401-3790, or you can email (e-mail address removed)

Here are some of the things I know I can do for you, because I have experience
doing them for previous clients:

* I can write custom web application, financial, graphical user interface, or
embedded software.

* I can write applications for Windows, Mac OS X, Linux and embedded systems.

* I can write device drivers for Linux or Mac OS X.

* I can develop software in Java, Perl, C, C++, Python, Postscript, and the
assembly codes for PowerPC, ARM, Thumb, and 68000.

* I am exceptionally skilled at debugging and performance tuning for any sort of
application. I once held a position as a Senior Software Engineer at Apple
Computer, where I did nothing but debugging and optimization. I only left that
work because I didn't have many opportunies to write new code, work I enjoy. I
diagnosed and fixed hundreds of bugs in the Mac OS, many of them very subtle and
difficult to reproduce.

* I can implement communications protocols in operating systems or embedded
devices. I have particulary strong experience in SCSI, Serial Bus Protocol 2
(SBP2), FireWire (IEEE1394), HTTP, and TCP.

* I have extensive experience in graphics and multimedia applications. I have
played piano for twenty years, and own a Fatar MIDI controller (a type of
electric keyboard), so I enjoy writing MIDI, audio and music applications.

* I have a B.A. degree in Physics from the University of California Santa Cruz,
with extensive work in scientific data analysis and modeling, both academically
and on the job.

* I've been making telescopes as a hobby since I was twelve years old, grinding
and polishing mirrors by hand, and from my University studies I have a solid
background in ray and wave optics.

* I like to write, and feel I write well. A manager at Apple once remarked that
a hundred page test plan I wrote when I was a QA engineer for the MacTCP network
stack was the best test plan he had ever read.

* I can slice, dice, julienne and puree.

I'm also interested in learning new skills on the job. I am able to do all the
different things I can because I have always placed a high priority on learning
new things. Because of the importance I place on this, I'm willing to cut a deal
with anyone willing to hire me for work I am not yet expert in.

I can do small and large jobs. The longest contract I've had required a year and
a half of work, writing a specialized database from scratch (from the low-level
file format to the C++ API) for a financial firm in the Bahamas, while the
shortest was a couple of hours, helping someone decide whether his company
should purchase a certain software package.

Thank you for your attention.
