    Looking to engage with some server side developer with good knowledge of server side technologies. Specially REST full APIs and their documentations (Postman/Swagger etc), Spring MVC and JBOSS. We already have a stable product running over a decade. Its written in Spring MVC. So in theory the job would demand, understanding a controller logic and write a new controller which is RESTful keeping the business logic exactly same. And authenticate the restful controller through authentication keys. Genuine developers who are freelancing themselves should contact. Companies who would get the job done by some of their members, may avoid reaching out to me.
