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 http://www.goingware.com/ and
find my resume at http://www.goingware.com/resume/
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 crawford@goingware.com
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.
