• New and further development of a B2B shop
• Configured and supported server setup, build, release, and configuration management were introduced
• In this project, prototypes for web services were created based on CXF and a WSDL-first approach, which are now used to build web services
• For a new section in the online shop, a new frontend was to be created based on Java EE and JSF. It is embedded into the existing shop via an iframe.
• The backend (DB, web services, additional data sources) needed to be accessed. To implement this modularly, I proposed an ESB.
• Since the onboarding effort was estimated to be very high, my alternative proposal was to implement the calls as EJB3 services.
