Experience

  • Hyperion
    https://pointintimecount.com

    I am the CEO and lead developer for Hyperion, an app to help non-profits across the country with the Point-in-Time (PIT) Count. The PIT count is an annual census of the homeless population done by tens of thousands of volunteers across the country.

    Historically, maps were handed out to volunteers showing them where to look for people experiencing homelessness. Each volunteer would bring a small stack of surveys to fill out with pen and paper. The surveys are often fairly complex, and the entire PIT count needs to be completed within 24 hours, and the bulk of the survey is often conducted at night. This led to hurried and often illegible answers, missed questions, and an all-around poor experience.

    I wrote an app that tells volunteers where to go with a map (such as Google Maps), shows them exactly the questions they need to ask (hiding the others), and instantly reports answers to the administrators (with geotagging and timestamps attached). The administrative dashboard helps administrators move volunteers around during the count, clean up the data, and more.

    Swipebite is a flutter app that lets groups of friends swipe at nearby restaurants. You can look through 50 restaurants in about a minute and find one that you and your friends are excited about. I wrote the app by myself.
