Senior Backend Developer / Full Stack Developer

Confidential, San Jose CA

Responsibilities:

• Using AOP and custom Annotation implemented generic request processing where all developer has not to worry about send the response to UI and doing Exception handling in their code.
• Implemented Generic Web Service Client Mechanism. So that in case if any new Web Service needs to be called we don't have to write the whole logic.
• We have to just pass the request and response class. Rest of the job will be automatically taken care by generic code base.
• Implement Generic Excel reporting Framework which only takes the list of headers and list of data and creates the excel report for the same.
• Using AOP and custom Annotation implemented User Access which is plug-gable component and can be inserted in any response to fetch the user access details. Which helped all developer to focus on developing their role specific modules without having to worry about fetch role details.
• Created foundation project Architecture for end to end request and response handling.
• Developed the application using Spring Framework that leverages classical DI architecture, Spring Boot, Spring MVC, Spring Cache, Scheduler, AOP
• Implemented persistence layer using Hibernate that use the POJOs to represent the persistence database tuples. These POJOs are serialized Java Classes that would not have the business processes.
• Used GIT for version control across common source code used by developers
• Used Rest Web Services using JSON to transfer the data between different tracks.
• Used JDBC template to invoke Stored Procedures.
• Used Spring Data to persist data.
• Used Spring AOP to measure time and performance for Java API’s.
• Implemented core functionalities, Service SKU creation, GSP Mapping, GSP De-mapping, Quick Map, PidByPid view, Product Pricing Strategy.

Environment: Workflow API, RESTful WS, Java 2 Enterprise Edition, Spring Core-4.2.x, Spring MCV-4.2.x, Spring Data-4.2.x, Spring Cache-4.2.x, JSON (Java Script Object Notation), AngularJS1.4 / Angular, JPA (Java Persistence API), Spring STS, Oracle, Toad, Maven, Tomcat 7, MongoDB.
