The customers are mainly medium to big sized companies in the banking and industrial sector.The size of the projects ranges from small to very big. The focus of my activities is developing, testing and maintaining Spring-Rest-microservices as well assmall and medium-sized java applications. DevOps is a natural part of my daily work ranging from server administration, CI/CD-Server (Bamboo/Jenkins) configuration, support in the creation of regression tests to configuration and development of docker images.
