  • 8tracks iOS App (Development)

    As the lead iOS engineer on the project—and the only engineer for a bulk of the time—I had complete ownership over the code base after inheriting it from the previous engineer.

    My first task was to finish a major overhaul of the design— which launched about 3 months after I joined the team—and received much praise and high ratings from the users.

    I developed features pragmatically, but with a vision for how to improve the architecture, and over time made the application more stable for its 1.2 million monthly active users.

    When building support for the video ads, my role also included frequent communication with the product team, ad sales team, and third-party ad networks—in order to increase revenue with minimal impact to the app's usability and stability.

  • Hipmunk iOS App (Development)

    During my short time at Hipmunk, I built features for fare alerts via push notifications, worked with the design and product teams to add new ad-hoc features to the app, participated in a design overhaul for the release of iOS 7, and solved performance problems for older devices.

  • Earthmate iOS App (Development)

    As my first iOS app project, I worked on the encryption features and the map download flow for Earthmate, the iOS app that pairs with the inReach satellite communication device for texting when off the grid.

    The map download flow included an API spec and development work on a C#/SQL back-end. On iOS, I integrated an HTML/JavaScript map framework for choosing a map region, and built both the networking logic and UI to manage map downloads and storage.
