Complete list of skills, by keyword:
2006 to present: Web Application Development & System Administration
osCommerce Zen-Cart customization (via: PHP,
SOAP, nuSOAP, XML, WSDL, adodb, MySQL, curl, cron):
+ Custom integration with fullfilment contractor, "ALOM"
+ Custom integration with FedEx shipment tracking
+ Custom scripting on 'thank you' page to support conversion (ROI)
tracking via apache logfile analysis with "Clicktracks"
http://www.clicktracks.com (transparent gif method requires using a file
'ct_ecommerce.gif' and the parameter 'ct_ecommerce' for the revenue
Created gk_formmail - a very
flexible HTML form processing script based on "tectite formmail"
"gk_formmail" includes the following enhancements to "tectite
+ All configuration options removed from HTML forms to PHP config
files resulting in:
+ Enhanced security (tectite formmail tries very hard to work
around a basic design flaw - leaving script configuration open to user
+ Separation of business logic from presentation (tectite formmail
leaves most configuration logic in HTML domain, including things such as
regular expressions for field validation that should be exclusively in the
PHP domain and unavailable to hackers)
+ Separation of form configuration from core logic, via separate
config.php files for each form handler (tectite formmail required
different configurations use a separate copy of the entire formmail.php
script, resulting in a potential maintenance nightmare; gk_formmail.php,
in contrast, is designed as one core logic file that serves unlimited
forms, via independent config files)
+ Optional suppression of all output in 'quiet mode', allowing
self-validating php forms instead of more complex multi-file redirection
(tectite formmail typically redirects to 'error page' or 'thank you page'
whereas gk_formmail offers the possibility of a single form script
functioning in various modes, via use of global variables containing error
message and other info)
+ Global auto-validation for email or other fields, avoiding the
need for tectite formmail's redundant configuration (via complex regular
expressions) embedded in each form
+ Improved organization of programming style (tectite formmail
logic scattered function definitions throughout main code logic, resulting
in difficult maintenance and debugging)
Jangomail customization and debugging
+ Management of databases and data collection in support of mass
email newsletter publications and subscription management
+ Design of database system to retain control of subscriber
records, independent of both jangomail and zen-cart

to ANSI SQL 'datetime' standard format

unsubscribe, database syncronization, notifications
