Maintain and write software

I am looking for a PHP programmer with advanced MySQL knowledge (MySQL functions AND stored procedures). This is for on going work on changes to existing systems, resolving bugs and new development of software. Software that we are working on should be friendly for desktops and mobile devices (tablets mainly). You must have proven experience in - Code Igniter, - PHP 5, - MySQL, (must know and understand triggers, stored procs and functions) - DHTMLX components (from [login to view URL]), - PHPGrid (from [login to view URL]) - JavaScript - jQuery - HTML5 - Excel (macros and functions) You will have access to a development server, which already has the software setup on it (running wamp). Mention 'mag' in your PM so we know you've actually read this project and are not auto-bidding on it. Looking for a freelancer that can work in similar time zone to the client (GMT +2). Some of the things we need done are: - Finalize implementation of user permissions and access control. - Connect between dhtmlx scheduler to phpgrid data so information can flow between the two databases. - In the CodeIgniter app makes some changes and track some bugs. - Convert excel spreadsheet to a PHP program We will provide specifications of what needs to be done and you will be expected to estimate how long it will take to do. Once we agree that the number of hours is reasonable we will give a go ahead for the work to be carried out. We estimate that the current work to be completed is about 100 hours. All your work is expected to be fully commented. This will be an ongoing project if you can deliver on the above. You must provide all necessary details in a PM and NOT in the proposal itself.
