We love technology, and love our mission even more. We like to use modern tools that keep us productive, but we're also willing to hold off that tempting migration project to ship a major user feature or launch a key partnership.

We use a handful of different technologies across our stack:

  • Android development happens primarily in Kotlin with MVVM architecture, Dagger2 and RxJava.
  • Backend writes most code in a JavaScript monolith backed by PostgreSQL. We are in the process of migrating to TypeScript.
  • Data builds with Python, SQL and Golang. We use Airflow and DBT for orchestration and modeling, Redshift as our primary data store, Kinesis and SQS/SNS for event messaging, Sagemaker and Personalize to train and score our ML models, and Tableau for data visualization.
  • DevOps works primarily in Golang, Kubernetes, Helm, Terraform and AWS.
  • Frontend development happens primarily in TypeScript, React and Next.js.
  • iOS development happens primarily in Swift, with a mix of UIKit & SwiftUI, utilizing MVVM when appropriate and backed by the Realm database.
