Finish Building a bespoke website-NO graphic design required

We started building our new website (which is an upgraded version of the current one) however the developer had to stop toward the end for personal reasons. The person chosen must have great English and be available to talk during Australian Time zones. There is flexibility to chat at times which suit depending on where in the world you are. Technical overview of the app: - Backend: PHP ver 5.6 (Framework: Symfony 3.2.13) - Database: PostgresSQL 9.5 - Frontend: CSS/XHTML/JavaScript(JQuery) with Twig Templates To run and maintain the app developers should be familiar with: PHP, PostgresSQL, Javascript (Jquery), CSS, HTML In general application is working as specified. What has to be done: - Admin panel UX Optimalization including better information handling on selected views and more intuitive linking between sections, better UI experience (fixing some CSS) - Better error handling - catching some backend errors and serving proper message in admin panel - Cut off time upgrade - now it's too simple, should be extended as Client expects. The application has been moved to Git repository and is available to copy. Steps required to install and run the app are included in the [login to view URL] file. After this is done, application should be tested and before going live please remember to upgrade information regarding email sending and payment api.
