The Task at Hand.

The process to be able to resell your used textbooks and the act of purchasing used textbooks is broken. It is quite hard for students to maneuver and a simpler way should exist. Many students rely on classified sites like kijiji and craigslist and have to meet off campus, with strangers and go out of their way to conduct at often times; a difficult transaction.

We have built a university specific web and mobile application that allows students to easily register (restricted to university users), and engage in a secure marketplace with everything you need to buy or sell.

Driving Design to Delivery.

The initial thought process going into this project was to figure out a way to keep their infrastructure intact while revamping the key components of the site, such as a homepage that details other aspects of the site, an updated calendar module for upcoming events, staff and associated partners information and better realized news and media page.

Whats Under the Hood?

At the core of Book X-Change is the MEAN stack – a JavaScript software stack for building dynamic web sites and web applications, consisting of MongoDB, Express.js, Angular, and Node.js; the MEAN stack provided a hyper-scalable, efficient, and JavaScript only solution to build Book X-Change from the ground up.

With the use of a service-oriented-architecture. We were able to reduce the workload on the client side by pushing all of our application logic to the Node API, not only was this time-efficient, this also allowed for seamless mobile development with NativeScript, a JavaScript mobile framework that retains the speed and functionality of any native application.

Book X-Change is secured with a JWT solution. JSON Web Tokens is an industry standard RFC-7519 method for representing claims securely between two parties; protecting the API as well as our users.

Book X-Change lives on the cloud. We use AWS EC2 to host the API and AWS S3 for the Angular application and static files such as book images, and profile pictures.


User Experience & Interface Design

Since the application is in partnership with York University we decided to implement the colors that represent the school, and utilizing secondary palettes of dark greys to a bright white. We wanted to make the visual interface appealing and easy to use, that way students can easily access the books that they require.

Screen mockups were initially built and put through a wireframe system rounding up to 50+ screens thus allowing a complete and thorough user experience.




A solution so simple and beautiful to use that students were raving about how simple it was to now buy or sell their book. We are still working on what else users would like, but our beta test was quite successful.

We are looking to launch our first solid iteration on February 2020 and then draft for other schools starting in Q2.


Post Launch.

It is a certain point that many people reach a logical conclusion that their website needs a fresh start to get off the ground. In this growing age of technology looking up a company’s website has become a norm, which is way of communication in making the right impression and giving visitors a reason to comeback. With SFAR it was only right that we implement a refresh to the company’s site and keeping up with the change in technology.
