Experience

ConnecDing

A complex integrations-based social media application, ConnecDing, featured a profile in which users could add links to their accounts on Instagram, Twitter, Facebook, LinkedIn, and 20+ others, to keep people better connected. It also featured groups that could be joined, each with custom messaging, post, and feed features. The application was on iOS and built using UIkit. I created a PHP Laravel back end hosted on AWS EC2 and connected to a MySQL database.

Wynd, Inc.

A two-sided SwiftUI-based social media application where creators can sell the rights to their content to brands. The main feature of this app is a TikTok-style video feed, where a user can like, save, view, or purchase a given video. It also features user profiles, followers and following other users, search features, and a custom video stitching and creation feature with music API integration. This app uses a Firebase Firestore back end with a Node.js API hosted on Heroku that serves Stripe functions and video storage, which is taken care of by AWS S3 buckets.

Samsung Remote

A sleek Swift/SwiftUI-based iOS app that can instantly connect to any Samsung TV and function as the TV remote. I got frustrated with constantly losing my TV remote, and when I did have it, I hated using it—so I made my own. I have some friends using it, too, because it's simply a nicer experience than using the physical one.
