Our current technologies stack is Java 8+, Spring Boot, Spring Security, Spring CLoud, AWS, Docker, Kubernetes. We have implemented a lot of projects. We have not only developed turnkey projects from requirements till the production environment setup and maintenance, but also reworked and upgraded unsuccessful projects started by other teams. We always write autotests for our projects, because it is essential for product functioning, and also for its successful evolvement. To run tests we use Junit, Mockito, Spring MVC Test. To keep documentation updated we actively integrate in our products the tools of API automatic documentation generation, as Spring Docs Rest and Swagger. We are always ready to advise you technologies that are convenient to your project implementation. If a client needs a system with ACID transactions, we will not impose on trendy technologies (Mongo, DynamoDb etc), but will choose and insist on relational databases, as PostgreSQL, Oracle etc.
