As a backend software developer, I can offer the service of designing and implementing a microservices architecture for your application using Spring Boot, Domain-Driven Design (DDD), Apache Kafka, MongoDB, Bitbucket, Bamboo and OpenShift. I will work with your team to understand the business requirements and design a domain model that aligns with them. I will then use Spring Boot to create stand-alone, production-grade microservices that implement the domain model and expose RESTful APIs. I will also use Git and Bitbucket for source code management and Bamboo for Continuous integration and Deployment. Additionally, I will use Apache Kafka for messaging and MongoDB for NoSQL storage, I will also use Hexagonal architecture to design a loosely coupled, testable and maintainable system.
