Work Experience
Wiley Publishing Compnay, November 2009
Technical editor for book "CCNA Certification For Dummies",
reviewed manuscript for technical accuracy.
Zarlink Semiconductor, June 2008-September 2008 (Contractor via Systems Pros, Inc.)
Implemented code for a chipset testing library per a specification written
in mathematical notation, implemented using the C language, PPC Linux, and
GCC/GNU toolchain. Used Subversion source code control system, including
branching and merging of source trees.
Slacker, Inc., August 2007 - February 2008
Re-wrote AVR assembly-language stepper motor control program in GCC.
Worked with Linux on an embedded platform (Cirrus EP9302 SoC with ARM9TDMI core).
Maintained makefile scripts for software projects.
Used Subversion (svn) to store source code.
Wrote IR remote control receiver driver for Linux.
Wrote Linux kernel driver and standalone driver to program Spartan 3 FPGA.
Wrote Linux user-mode driver to control an I2C device via GPIO pins.
Did minor microscope soldering board rework to connect probe wires to SMT devices.
Used Intronix LogicPort logic analyzer to debug hardware signals.
Used Abatron BDI2000 JTAG debugger to debug boot code.
Cisco Systems, Inc., November 2000 - October 2006
Wrote ARM assembler and C code to initialize and operate a custom
Ethernet packet capture card using an IXP-1200 Network Processor.
Maintained current and legacy C++ code for and added performance enhancements to
an Intrusion Detection System. Wrote and tested new Intrusion Detection
System signatures. Analyzed TCP/IP sessions to identify anomalies. Used Clearcase
version control system for source code management.
Southwestern Bell Corporation Technology Resources Inc.,
Perl Programmer/Unix Administrator, August 2000 - November 2000 (Contractor via The Maxim Group)
Wrote Perl scripts and Unix shell scripts to automate data collection.
Assembled and configured Sun Sparc systems (Enterprise 4500, Ultra 60,
SparcStation 10/20) with the Solaris Unix operating system.
Autogas Systems, Inc, Programmer, May 1996 - July 2000
Programmed and maintained real-time embedded systems using 6809
assembler, and C++ on Windows NT, to control major brands of gas pumps
and pay-at-the-pump terminals. Wrote MS-DOS batch files to automate
code generation process, and Turbo Pascal utility programs to convert
data for debugging.
Radio Cap Company, Programmer and Help Desk, Oct 1995 to May 1996
Wrote software in Pascal to automate the storage and retrieval of artwork
on their Appleshare Mac OS file server. Performed help desk functions
when necessary.
Self-employed, Shareware Author, 1992 - 1995
Wrote the shareware utility SoundMaster in Pascal and 68000 Assembler
for Mac OS.
InMar Group, Programmer, May 1990 - Jan 1992
Wrote an adware program for Buick using Object Pascal to run under Mac OS.
This included a simple 3-D golf game.
OAO Corporation, Systems Analyst, July 1988 - May 1990
Developed and maintained utility programs and subroutine libraries in
Turbo Pascal for MS-DOS as support software for programs to test individual
learning abilities for the Learning Abilities Management Program of the Air
Force Human Resources Laboratory (AFHRL) at Brooks Air Force Base.
Implemented a hardware and software upgrade to a system used at Lackland
AFB. This 68000-based system ran a UNIX clone called Regulus. Added a SCSI
1.2 megabyte floppy disk and a 40 megabyte hard disk to the system, and
rewrote the boot ROM (68000 assembler). Wrote a utility in Turbo Pascal to
read the floppy disks from this system on MS-DOS machines.

Non-work related experience
Linux/Unix System Administrator and Webmaster
I have been running my own web site (xi6.com/fanboy.net) over a DSL
connection since March 2000. The site currently runs on OS X 10.4 (it
formerly ran on Slackware Linux), and runs Apache web server with
mod-perl scripts, ISC DHCP server, BIND DNS server, and Sendmail SMTP
e-mail server.
