Hi there,
As the project details requires a tricky loop to add and run, so here is my short recap:-6 years experience:
CMS: WordPress, Joomla |E-commerce: OpenCart; | Lang: PHP+MySQL, JavaScript,Python
DB: PostGres, NOSQL for non-transactional data;
For the last half decade I've built likely 35 interactive, web-front application and corporate sites for clients.
Hand me the details and Proto-type you have in mind and let’s get the task done.
