Experience
Fitness and Nutrition App in React Native
I developed a leading fitness and nutrition app for iOS and Android in React Native. The project involved creating a Node.js back end to talk to a Shopify back end to pull all the data and developing the React Native application to use the API endpoints.
Owe—iOS Debt Tracker and Planner
https://apps.apple.com/us/app/owe-debt-tracker-planner/id674210560?ls=1An iOS app that tracks debts and payments, allowing users to track their finance and check who owes them and whom they owe.
Since it was a part-time project on the side, I developed the entire application, including all of the graphics assets. The app includes functionality to track recurring monthly and weekly payments, which is achieved using a local SQLite database on the device.

Music Roulette
https://apps.apple.com/us/app/music-roulette-music-guessing/id1086459730?ls=1Music Roulette is a music guessing game that lets users create an anonymous playlist perfect for parties or long journeys. It allows users to join and add songs to an anonymous playlist. Users can play the playlist and guess who added each song.
I developed an iOS application written in Swift and used Firebase to store all the data and authenticate the users. The app uses Spotify SDK to allow users to search for songs and play the playlist.
