    Project Manager and Joomla CMS developer

    Sri Lanka - Last active: 1 day ago - Tests: 5 - Portfolio: 13

    I build websites on Joomla! CMS, I build teams to develop websites and web applications, and I project manage those teams throughout the development cycle. I have a MSc in Computer Science, a bachelors degree in Law, both from London (UK) universities, and over 15 years of industry experience. I have worked at management level for several large companies and public sector organizations in London, UK. I now specialize in web project management (web sites and web application development), and developing and maintaining sites built on the Joomla! CMS platform. I am focusing on Joomla! because, after many years of CMS development with open source and enterprise software, I believe it is one of the most robust, scalable and extensible CMS available right now, open source or otherwise. It satisfies the requirement of 90% of websites that clients seek to build, namely, an attractively designed and user friendly front-end connected to a database, and the site and content easily administered via a back-end application. I think Joomla! provides the most cost-effective solution to this requirement. Previously, I have worked as a Web Project Manager, Web Developer, Web Designer, Web Master, Help-desk support, and even as an office/finance manager for a barristers' chambers.

However, I can also use the following Adobe software packages: DreamWeaver, Flash (with ActionScript 2), PhotoShop, Illustrator. General skills ------------------------------------------------------------------ ► Online marketing - I have used a variety of software solutions for online marketing, web traffic analysis and advertising. ► Technical documentation and report writing. ► Feasibility studies and supplier evaluation.
