We are looking for a Web Analytics Software Developer to help us create a simple analytics tracking tool that works as a very much simplified version of Google Analytics for our customers. This will work in a few stages. 1) The customer will sign up on our website and will have a login and password to their private analytics dashboard. 2) On their analytics dashboard they will be able to find the <script> to add to their website which can be used for tracking. 3) Once the <script> is added to the website, the dashboard will self-populate with commands such as visitor numbers and traffic channels (Please see http://analytics-dashboard.co/demo/wp-admin/index.php?page=analytics) 4) The analytics dashboard although very basic (http://analytics-dashboard.co/demo/wp-admin/index.php?page=analytics) will have search facilities such as date range and will have a separate account or profile page. A suitable developer must have experience setting up this or a similar system like this before and I feel that it is a must for the individual to have the following skills: • Strong C++ skills • Multi threading • Linux/Unix experience • Familiar with SQL, Python and Javascript • Experience in all phases of the software development life cycle • A passion for problems solving and a pragmatic and adaptable outlook. The areas we are happy to be flexible on to save money are the following: • Our company setting up the dashboard ourselves on behalf of the customer • Using the same analytics dashboard interface seen in this link (http://analytics-dashboard.co/demo/wp-admin/index.php?page=analytics). Then making adjustments to the code so that it can work independent of WordPress. The areas of concern will be the following: • In the future, we will be looking to extract certain elements of data from each individual dashboard and compile it in a separate administrator panel. Although this is not to be built yet, please consider this when deciding which code to use. • We will need a large server that will be able to store large sets of visitor data for up to 12 months. If you are interested then please contact me immediately so that we may be able to discuss this further.
