This project involved building an interactive catalogue web application with items in various categories. I chose to implement a catalogue of animals organised into high-level categories.

This is project 3 of Udacity’s Full Stack Web Developer Nanodegree course. To see my other projects, go to

The web app was built using the Flask framework (Python) and used SQLAlchemy to interface with an SQL database using object-relational mapping (ORM). It uses the Jinja2 templating language to render HTML output.

The app supports full CRUD (Create, Read, Update, Delete) functionality of the animals, with users logging in using OAuth providers Google+ or Facebook. Users are also able to upload a photo of the animal.

The front-end uses Google’s Material Design Lite framework.
