My expertise includes the following areas of web programming and design:

• Perl/CGI
• PHP
• MySQL
• (X)HTML
• CSS
• WordPress
• XML
• Javascript

I have gained Many years of experience, especially with the following project: 

inthotels.com – hotel booking portal

I did all the programming for the portal: hotel search, booking wizard, login system for booking guests, intranet (backend) for the hotels, XML interface for channel managers, automatic accounting for the hotels. 

For the implementation mainly Perl/CGI and  Javascript/AJAX are used. 

The database server is MySQL, the system runs on Suse Linux Enterprise Server.

The hardware (RAID 10 array) was also assembled and installed by me.
