- What I can do for you...
I have many years of experience in Server/System Administration for Unix and Linux.
I currently manage a network of Linux (CentOS & Ubuntu) servers used for my
Six plus years using PHP-5 (OOP) in both server-side & CLI roles. Developed
several extensive class libraries providing a range of services and abstractions.
Have also developed sites using the Zend framework environment.
Eight plus years using Perl 5 in both online (CGI) and command line (CRON/shell)
roles. Developed many Perl packages (.pm) using OOP and class extension.
simple form validation thru complex, interactive applications
such as online calculators, analysis, etc.
Four plus years using jQuery with several plugin libraries.
Have developed jQuery plugins when needed. The nice thing about jQuery
is that you can almost always find an open-source plugin to provide a
particular control or effect.
My interactive sites use AJAX in order to enhance the user experience.
I also use JSON as the means of exchanging data. I've done both server-
side creation of finished html and client-side creation of html from
JSON data provided by the server.
Eight plus years using MySql, MariaDB, MySql Workbench and phpMyAdmin. I've
also worked with SQL server and Oracle database but most development has been
with the MySql environment.
I don't use a visual editor like DreamWeaver to develop pages. Most of
the time I write html and css directly in my IDE (NetBeans). Thus, I am
very experienced with hand-coding for html and css using web resources
for color tables & other reference data.
I am experienced with software version control using GIT and maintain a
repository on GitHub.
I have installed, configured, customized and maintained many open-source software
packages such as CMS packages, Blog software, BBS software, CRM packages, etc.
- What I've done...
This project is my latest and greatest. I developed this "home" page years
ago for my personal use back when the Web was just getting popular. It keeps
all my bookmarks and frequently used sites instantly available. Shown here
with my own special class library and extensive AJAX for support pages. It's
fully compatible with desktop, laptop, tablet and mobile devices.
four financial calculators for a mortgage broker client and then combined all
of the functionality into a single calculator which can be included into any
simply included into a page at the point where it is to be displayed. No function
calls or setting variables needed, so it can be used by any level of developer.
This site is an interactive moving cost calculator I did for a carrier in Chicago.
the step-by-step process. This calculator produces the results and then feeds a quote
management system on the backend written in PHP and used by sales agents to
correspond with prospective customers.
Much of what I do involves administrative and/or private pages for use by the
site owner or agents. As such, these are usually password-protected and not
available for viewing by the public. I do, however, have a .PDF project book
which contains screen shots for some of these web applications. The file is
fairly large--about 2-3MB.
- The Basics
- What I'm looking for...
I work on programming and
sysadmin projects because I enjoy them. I still spend a part of each day managing
my own cloud servers for Your
Showcase and doing custom programming for my long-term hosting customers.
I work from my home, actually my ranch, in Texas, USA. I have a complete
array of both Windows and Linux workstations that I use over my fast Internet
connection to work with servers and projects around the world.
I'm looking for interesting server networks and programming projects where
I can provide a significant contribution, either as a solo contractor or a
member of a virtual team.

- Programming examples...
These are just some representative examples of the kinds of programming and
languages that I use. For a more complete repertoire, check out my repo on
This example is a php class that is actually part of my large PHP helper library. I
developed this as a way of standardizing the handling of dates. The design criteria
was 'anything in--standardized out'. That is, I can construct an object for this class
with new Date("7/6") or with new Date("2010-07-06 10:24:00") and get the
same standardized Date object. Once objectified thus, there are methods for comparing
date objects, moving a date object by +/-nn months/years/days/hours/etc., producing
legitimate format strings representing the date and a terrific method that builds
(MySql) date format (yyyy-mm-dd hh:mm:ss) in the POSTed data.
This Perl package I put together to use as an alternative to Lincoln Stein's CGI.pm.
The CGI.pm package is almost 200kb in size and I wanted something much smaller that
still included the basic functionality necessary for CGI programs/scripts. So, this smaller
class (Cgi.pm) includes CGI input processing--including multipart-forms data, html headers,
cookie processing and a few other things.
a multi-functioned mortgage calculator in a page. It can be inserted into any page and
give it interactive financial capabilities.
This is a Java applet I wrote for a mortgage broker's site. It presents a graphic depiction
for financial indices data (Prime,COFI,Libor,etc.) over a variable period (in years). The
total applet consists of this file and about half a dozen separate class files for the
various objects used in the display and contained in a JAR file.
