  • Jukebox App

    For my senior project in college, I developed a “social jukebox” music app for iOS. The idea was to allow users in the same geographical location (ex. Student Center) to connect to a virtual jukebox and add songs to a queue. Users could then upvote/downvote songs to re-prioritize the queue, adding a fun social aspect to the traditional jukebox.

    The jukebox was a custom music streaming server I built running on Raspberry Pi. The Raspberry Pi would be connected to a sound system (since that's where the music plays from) and users would just have to be on the same WiFi network in order to see/connect to the jukebox (just like a Chromecast). The jukebox server was connected to Spotify's API allowing full access to their catalog of music.

    I ended up testing a pilot for my university's student center.

  • PRISE Life

    PRISE Life is a health/fitness app running on iOS and Android that allows users to receive a customized meal plan based on the Protein Pacing diet. It also provides access to a catalog of exercise videos and routines that can be streamed anytime.

    I designed and developed the entire app using Flutter, Firebase, and AWS Lambda + API Gateway. Currently, there are ~500 users on the platform.

  • DFS Data Scraper

    A friend and I are developing a model for generating optimal entries into Daily Fantasy Sports (DFS) contests in order to maximize profits based on available sports data.

    In order to collect and aggregate data for the model, I developed a web scraper using Puppeteer (headless browser) to scrape numerous historical datasets from popular sports data sources. Most sites do not have APIs so I had to write custom Puppeteer scripts that could deal with things like logging in, filling out forms, and clicking buttons. I was able to successfully scrape data for 4 major sports across 3 different sites.
