Various trading systems were being built as microservices and our client needed developers with knowledge of technology stack. We were required to on-board existing teams and help them to develop the services.
Kafka was used as shared communicating service - service bus - for all services. Redis was used as highly performant caching mechanism to handle the traffic from the web. Elastic search was used for logging across all microservices.
We have worked on various services across the whole enterprise and successfully delivered the solution.
