Our system is a set of Java Dropwizard services deployed to AWS, interacting with thousands of Android tablets using modern payments hardware, as well as with partners through our API. Payment processing is a key source of Toast’s revenue and also the lifeblood of our customers’ business: we process millions of dollars in transactions every day.

Our Tech Stack

Our products run on a stack that ranges from guest and restaurant-facing Android tablets to backend services in Java to internal, guest-facing and restaurant-facing web apps. Our backend services follow a microservice architecture written using Java and DropWizard; we use AWS extensively, ranging from DynamoDB to RDS to Lambda. We have our own platform for dealing with user management, canary deployments, and robust load balancing. We store data in a set of sharded Postgres databases and utilize Apache Spark for large scale data workloads including query and batch processing. The web front-end is built using React and ES6. Our main point of sale application is an Android application written in Java and Kotlin. For data between tablets and our cloud platform, we rely on Pulsar event driven architecture along with some RabbitMQ clusters as well as direct tablet communication to the back end.
