• Most of our services are written in Flask or FastAPI. We’re also utilizing AWS Lambdas, and internal framework where it makes sense
• For communication between components we are using RabbitMQ and REST APIs

• Everything we run is deployed in Kubernetes clusters to ensure reliability and scalability. Currently, we use AWS in three regions, but we are mostly cloud agnostic.
• We operate quite a few lambda functions, our customers are able to customize the behavior of the product with just a few lines of code (Javascript or Python).
