Inspiration
Many senior students have stuff that they want to sell when they move off campus or graduate. However there lacks a user-friendly platform for students to trade second-hand items, and many of them ended up being discarded. So we made this website to help reduce waste and save $money$.
What it does
It allows students to log in with their AndrewID and buy/sell items. It also features smart recommendation which suggests products that students might need based on their personal info.
How I built it
The core of this project is a smart recommendation algorithm that predicts consumer behavior. We created a graph that represents the correlation between certain user identifier and the category of items they purchase. A larger edge weight shows a higher correlation that informs Carmazon’s recommendation.
Challenges I ran into
One challenge that we have ran into is to display the item information uploaded from the user (because our team have limited web dev experience). Instead of having the content uploaded from the user directly posted on the website, we (will have to) manually post items.
Accomplishments that I'm proud of
We have an kick-ass UX design!!! We also came up with a simple solution (it’s freshman level) to constructing a user portrait and perform smart recommendation.
What I learned
We learned about the overall process of web development, including server + database building, UX design, HTML/CSS. We also found it helpful to break a daunting task into smaller tasks in order to tackle it : )
What's next for Carmazon
-Streamline the posting process -Incorporate machine learning API to better predict user behavior & auto-identify items when uploading -Make it adaptive to mobile viewers
