Project: Omni EXP AG

Environment: Spring, Spring MVC, Hibernate, REST, Spring Boot, Microservices, Docker, AWS
Description:
Omni EXP AG automates work processes by using workflow. Through a series of pre-determined rules and settings, work items, called “tasks,” are pushed to the appropriate operators for processing. Tasks are routed to queues called “action steps.” Each task includes a series of required action steps that must be completed. As tasks move from step to step, each operator performs the necessary procedure to complete the customer’s request.
