• New development and enhancement of a B2B shop
• Configured and supported server setup; introduced build, release, and configuration management
• In the project, prototypes for web services based on CXF and WSDL-First were created, which are now used to develop web services
• For a new section in the online shop, a new frontend based on J6EE and JSF had to be created. It is embedded via an iframe into the existing shop.
• It needed access to the backend (DB, web services, other data sources). To implement this modularly, I proposed an ESB.
• Since the learning effort was estimated to be very high, my alternative proposal was to implement the calls as EJB3 services.
• As part of introducing the new technologies, the build was done with Maven. To test and evaluate the sources, Jenkins, Artifactory and Sonar were set up and I introduced the team to how to use them.
