Php & MySql

I have a lot of experience in using open source php & MySql web applications. I can install, customise and design themes for sites such as Drupal, Wordpress and Joomla. Recently I have been coding my own php pages which I've connected to custom built MySql databases.
Drupal

My favourite CMS. Drupal is the most flexible of all the content managers and also one of the most powerful. It's highly modular and elegantly coded. I consider Drupal an excellent solution for almost any web project, which is why I've used it exclusively for the last 2 years.

Ubercart

The Ubercart webshop module for Drupal is excellent. If you are considering building a webshop with tons of great features, scalable to any size with the back end power of one of the best content managers around then you can't do much better that ubercart. Plus of course, it's all open source.

osCommerse

This was once the best open source software available. I wouldn't suggest anyone use it these days as it's a complete pain to work with and the back end code is a real mess. Maybe they'll bring out a new version one day, but I think this project is over.

Phorum

If you need a simple forum website then Phorum is a very nice solution. It's very quick and powerful but I would usually point people towards using Wordpress these days.

Gallery2

This is definitely the best open source gallery software there is. It has a very active community who regularly make great updates to their software. Cutting edge stuff.
