    Jamr is a Swift-based social media application that allows musicians to connect with others in their area.

    I was a co-founder of this company alongside a musician and marketing expert I met while traveling. It is supported by a Firebase back end that I developed and features a chat system using the Firebase Realtime Database, cloud storage for user profile photos, authentication, cloud functions, and push notifications.

  • Jamr

    Jamr is a React Native social media app designed for musicians to connect with others in their area. The project was built with myself as the sole developer for the front end and back end, which provided a wealth of experience in every step of the process of ideating, implementing, and iterating on an idea from its conception to its release.
