Our Tech Stack

Toasts products run on a stack that ranges from guest and restaurantfacing Android tablets to backend services in Java to internal guestfacing and restaurantfacing web apps. Our backend services follow a microservice architecture written using Java 8 and DropWizard; we use AWS extensively ranging from S3 to RDS to Lambda. We have our own platform for dealing with user management service elevations and robust load balancing. Toast stores data in a set of sharded Postgres databases and utilizes Apache Spark for large scale data workloads including query and batch processing. The frontend is built primarily using React and ES6. The main Toast POS application is an Android application written in Java and Kotlin. For data between tablets and our cloud platform we operate RabbitMQ clusters as well as direct tablet communication to the back end.
