Experience

Esports Tournament Application

A Flutter-based application that enabled users to log in to the app and create esports tournaments.

Grocery Store Application

Developed a Flutter-based grocery store application that allowed customers to log in as users or shop owners.

The user was allowed to view the items available in the store and add them to the cart. The user can then purchase the items, make a payment, and place the order through the application. Store owners are allowed to view the orders and update their state accordingly. Furthermore, the user could also track the status of the placed order.

This app also included speech-to-text conversion for search functionality.

Bank Account Opening App

A hybrid mobile application is used to automate the process of opening bank accounts. The application was built using Cordova, and I also used HTML, CSS, and JavaScript.
