RingCentral

Java developer
I participate in the Ringcentral Webinars development team. This product has many micro-services. One of them is the brand new micro-service responsible for marketing webinars (Process of users registration). To successfully process a large number of simultaneous registrations, the service uses Redis as a cache. The service uses Amazon SQS to send messages to the queue after user registration. These messages are used by another service to send emails. Apache Kafka is also used to communicate with other microservices. Our service listens and publishes messages to topics. Service provides useful REST APIs for getting information about registrants, session and e.t.c which are used by other micro-services or UI. I have been involved in the development of this microservice from the very beginning and implemented such features as: integration with Redis, integration with SQS. Implemented APIs for creating and cloning sessions. Implemented public APIs support and so on.
