PROFESSIONAL EXPERIENCE

Confidential, Burlington MA

Senior Java/J2EE Developer

Responsibilities:

• This framework is a custom framework (like Jersy and Rest Easy frameworks in teh market) designed and developed based on teh REST concepts. This is a very generic framework dat supports heterogeneous clients and can interact with heterogeneous systems. We has extensively used several advanced concepts like REST, java generics, reflection api, xml technologies, several design patterns, etc,
• HCM (Mobile version)
• BI analytics(Mobile Version)
• This framework acts a generic layer between heterogeneous systems and acquires data. It TEMPhas several in built generic components dat can be used to interact with other web service based legacy systems, Mobile friendly (REST)APIs, Fusion binding layer, etc.,
