He's passionate about working on things that matter -- be it a mobile application to make music in interesting ways; a web application to help students buy textbooks; or a data pipeline of video advertisement analytics. He's spent the better part of the past two years working as a full-stack engineer at Twitter on the video monetization team.

Employment
  • Software Engineer

    • Utilized full-stack experience to create a video-level system of analytics. Contributions included everything between time-series data aggregation to front-end React development.
    • Contributed to video advertisement interpolation in live-streaming Thursday night NFL games.
    • Supported work to read video advertisements from and deliver usage analytics to third-party ad servers using the VAST video advertisement standard.

    2014 - 2014
    • Built a Windows mobile app, Sound Stack, that allowed users to play instruments and record songs using loops. Instruments used mobile sensors like the camera, gyroscope, compass, and of course touchscreen.
    • Worked exclusively on the drumming instruments. Using the phone, users could "play" the drums in front of them by hitting spaces oriented around them.

    • Built a web application to help students find deals on their class textbooks and schedule their courses.
    • Wrote spiders to get course information from school catalogs for course scheduling and textbook matching (students could input courses and get back books, where there was no centralized book listing).
    • At peak, had 10K visits per day during the first week of classes. The first year of operation resulted in commissions on over $120K in sales, and saving students $285K in textbook cost (with an estimated 30% price savings).
