Project Description:
We need to build a wordpress plugin.

1. wordpress plugin should support wordpress permission so that admin can configure access to plugin via wordpress user administration and permissions. It should integrate nicely and adjust to wordpress configured theme.
Bottom line: we need experience programmer that can enforce wordpress coding and design best practices.

OPTIONAL: can you provide some best practice for unit testing of this extension ?

2. the plugin will query financial data through a REST/JSON or REST/csv API and plot the result with http://www.highcharts.com/ a javascript charting library
The REST API provide access to a complex financial computation platform that we are developing

3. the plugin will display a dynamic query form. The query does not fit into a static form.
For example , user can select multiple date intervals. This could be implemented with a button "add interval" that trigger addition of 2 date picker input. We have 4 other dynamic part in the query like this one.

OPTIONAL: We prefer someone working with agile approach and familiar with git.

We will consider several applications:
a. building the wordress integration and sample code for dynamic form and REST calls. Then our developer will join to fill in the detail of implementing all forms option and full REST API calls.
b. building wordpress integration + full forms options. We needed a creative UX expert in that case. Our developper will eventually handle REST API and highchart integration.
c. building the whole system based on detail requirements we will provide.

In both cases code quality and maintainability will be a priority.
We need someone available full time ready to start before end of the week.

Skills required:
AJAX, Javascript, PHP, Wordpress
