With all key features developed, we are developing additional features and stabilizing the platform, which serves hundreds of servers and TBs of RAM to handle thousands of requests per second.

We are currently looking for new Site Realiability Engineers to help us maintain and improve the system it can grow much further without our customers noticing any hiccups.


Our platform:


The Overall Exponea architecture is inspired by Lambda architecture. For data ingestion we use an asynchronous API with basic input validation. All such events are put into Kafka for further data processing. We use several data storages for specific use cases such as MongoDB (primary copy of most of our data), Redis (cache, fast access, unstructured) and RabbitMQ (campaign workers). For several use cases we provide real time analysis API that triggers computation or data retrieval from our proprietary in-memory analytics engine.
