Our application is developed using RoR and our web development has been around Bootstrap using a materialize css framework. We require you to have experience in this area. We would like quotes for both HTML implementation and providing the code separately. Thank you Tue, 25 Jul 2017 05:21:05

Simple Rails Project (code provided) to Drive Referral For an eBook Launch Page

We're looking for a highly motivated, client-oriented developer to develop a referral mechanism for our splash page for a new e-book launch (note: not a physical product). The main mechanics: automatically generate a unique code for every unique email address entered, and append that code onto the given URL. On the front-end: Create a page with a shareable link (to the splash page) coded specifically to the visitor.  There should be buttons below the link for visitors to share the link via email, social media, i.e., Facebook, IG, Twitter, etc. with the click of a mouse. By sharing the link with friends, visitors will receive the e-book for free, along with other bonus items, such as templates, worksheets, etc. - depending on how many friends signed up using the unique referral link.
