Experience

Esports Tournament Application

A Flutter-based application that enabled users to log in to the app and create esports tournaments. Other users can then log in to the application as players and participate in the tournaments created. This application automated the whole flow of creating tournaments, player registration, creating matchups, finalizing the results of each matchup, declaring a winner, and distributing prizes, if any.

NFT Marketplace

A marketplace where users can sell, view, and purchase NFTs. The user can view and follow different NFTs creators, view and like game-related NFTs, the NFT details, list an NFT for sale, and purchase NFTs. The user is required to connect a Blocto wallet to list or purchase NFTs.

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. The application contained forms and documents attachments required for the account opening and sent to the server. The application also tracked the status of the account application.

IMDB Movie Listing

https://imdb-titles.vercel.app/
