Update social network website - 30/10/2017 11:54 EDT

Hello, I am an business investor who just purchased a website from a low level programmer. The website is a social network with potential but its filled with bugs, incomplete functions and other low level algorithms. The website is available for desktop and mobile website both of which share similar errors. The website is pure HTML5, CSS3, PHP, MySql, JavaScript, Ajax, slight Jquery and Bootstrap. The database is already designed and in place, but during your work I wouldn't mind if you made any changes for better performance. Before I share the link, here is the amount of work I need to be done on this website for both desktop and mobile. - Complete analysis of the entire website to identify bugs ( I already know most of them so I am ready to walk you through easily) - Fix all bugs found in Desktop and Mobile website. - Improve and optimize all existing functions to run perfectly. - Improve the desktop website interface to run on different screen resolutions. ( Currently it is running on 1366x768) - Add real-time / Dynamic effect to enable the website to update automatically i.e statuses, likes, messages and notifications. - Improve media upload i.e. images an video. There will be more instructions on what else is needed to be done. But from a programmer familiar with social networks you'll get what am trying to accomplish. PS. Languages I expect apart from what I have stated above include: C#, Python, SQL, ASP. NET, E-lang ( Optional) ETC. Thank you.
