Does your website use any Database ? We will get the codebase from github. If your friend has kept the database back-up on the git hub, then we can retrieve the website.
Otherwise we have to inspect the code if any Database Schema is available on the code base that will help us to build the database. We will connect the database to the codebase.
If your website were using a SAAS solution like Cloud 9 or SalesForce for managing the data then concern with the database is not sever.
Do you have a hosting server and the domain name ?
We also need to know the technology used for your website. We work on three main web technologies.
LAMP Stack ( Php/mySql/PostgreSql)
.net platform
Java/J2EE
We also have the expertise on working with a website with frontend technologies -
HTML5/CSS3 , Bootstrap, Javascript/Jquery, Angular Js/Backbone.
We have also worked on Nodejs and no-sql like MongoDB.
Please provide us the access to the Github repository. This will help us to understand your system.
