Projects

Skill-Matching at UVA

Jan 2019 - Present

Helping students find each other

As a student, it's not easy to find someone who's taken your class, had the internship you're interviewing for, or led the club you're reaching out. Or maybe, you're looking for a student photographer or tutor, but where do you even start looking? We're building a UVA-internal skill-matching marketplace, the go-to place to find other students.

Ride-Sharing at UVA

Jan 2019 - Present

Connecting students for carpools

As a university student without a car, finding a ride to the grocery store, to downtown, or even to home is a struggle. I want to be able to get to where I need to go, but cheaper than for an Uber or Amtrak ticket. And if you're a driver, you're not changing your routine. If you go to Kroger's every Sunday, then just drop a ride on our app, pick someone up, and get your gas paid for -- simple as that.

Cavalier Symphony Orchestra Website

For CSO

Squarespace website for all club needs. I decided to use Squarespace because it's maintainable by anyone on the orchestra exec board and has a comparable cost to hosting a custom website.

TheCourseForum Search v2

TheCourseForum Search v2

Sep 2018 - Dec 2018

New and improved search service for TheCourseForum

Rearchitected the search service for TheCourseForum, a course review system for UVA. Where the previous system used substring matching, our prototype fuzzy searched on indexes including the course reviews, capturing student "slang" for courses (e.g. "orgo" = Organic Chemistry). This dramatically improved all search metrics.
