Nature of work
· API and service implementation
Builds JSF/Java ERP front ends and reusable J2EE modules, while partnering on REST/SOAP APIs, integrating external web services, validating client input, and tuning code for responsive, scalable behavior.
""Developing with the back-end developer in the process of building the REST/SOAP API.""
Tech stack maturity
Mainstream Legacy
The skill set centers on J2EE, Java, REST, and SOAP, which is typical of established enterprise backend systems that are widely used but not cloud-native or bleeding-edge.
