Used technologies: Java, GWT, docker, Kubernetes, NoSQL database CouchDb, Amazon Web Services.Along with supporting the application, I took a part in the automation of the build process and implementing Continuous Deployment of the application to the cloud.Took an initiative to change the design of the application to make it possible to run it in the docker infrastructure and deploy it to AWS Kubernetes implementation (EKS). This is the most interesting part of the work as Kubernetes is a cutting-edge technology that gives a lot of benefits in deployment and supporting applications in the cloud.Took an initiative to migrate a single NoSQL CouchDb installation to clustered CouchDb to make it more stable in the production environment. Clustered CouchDb implementation was done with Kubernetes in AWS.Apart from the main product, I designed a web application tool for performing migrations from one database state to another. This tool has been written using these technologies: Java, Spring Boot, VueJS framework. To make sure the application works correctly, unit tests and integration tests have been developed. Integration tests are run in a docker environment using testcontainers framework. The application was also deployed and run in AWS Kubernetes implementation (EKS)One more initiative from me was the developing UI testing framework based on the Selenium, Docker, and test containers framework. With this framework, it was possible to write and run UI tests for our main application using docker containers and integrate them into the Continuous Integration server (Jenkins) without the need to run these tests on a physical or virtual machine. When the core for this framework was done, we delegated the responsibility of writing UI tests to the QA team and all the tests for UI were written by them. Show less
