Our Tech Stack

Toasts 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 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 front-end is built primarily using Angular 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 and Pulsar clusters, as well as direct tablet communication to the back end. Toast leverages standard enterprise applications such as NetSuite and Salesforce for key business operations.

"I looked at a lot of start-ups during my last job search and Toast was by far the most exciting. It was instantly obvious to me how the product is useful to people and why someone might want to buy it. The proof of that has been in the way we have grown and the excitement we have already generated. However, what really excites me about the company is that I feel like we are just scratching the surface in terms of what we can accomplish. There are SO many untapped opportunities around our product and as we continue to grow, I am excited about being able to explore them more.​"
