Ipsum: This unimaginatively named product was built over a period of 5 months with a friend as a shop management and online physical store helper. The project was built on Django with the user facing part having a search feature for products and shops, complete with directions and a feature to add multiple items for different shops and get the path on Google Maps using the MapsAPI. The business side involved a basic CRUD based management system to maintain the inventory and create a profile. The project was later hosted on a Heroku server. I gained experience working on a Web IDE ie. Django, HTML, CSS, Python and using ORMs.
