Experience
Food-ordering App
A Django and Vue.js-based application allows a restaurateur to register their restaurant and provide their menus. A customer can search for restaurants on the basis of names, cuisines, and amenities. They can add items to their cart and place an order. The customer can review the order as well as the restaurant based on their experience and their reviews are publicly available. The number of stars a restaurant receives is decided by ratings.
I developed this entire project alone including the front and back ends.

COVID-19 Dashboard
I built a multilingual dashboard to showcase the COVID-19 trends across the world. The pandemic and lockdown brought about a major change and the misinformation about it was causing unprecedented fear amongst people. To combat that, this dashboard gave a clear view of how it's trending and affecting each country. The dashboard had widgets to show heat maps of state-wise distributions of cases in India and trend charts to show the day-by-day change.
Algorithm Visualizer
A VueJS-based application to help visualize various algorithms. You can play around with various options to create different scenarios and how an algorithm would run in each of those scenarios. I have implemented various sorting and pathfinding algorithms.
