● Worked on Lambda Expressions, Functional interfaces Stream API's, Time API, and Improvements on Collection, Concurrency, and IO improvements by using Java 8.● Developed and implemented Restful Web APIs, and exposes endpoints using HTTP methods like GET, PUT, POST and DELETE.● Implemented multi-threaded synchronization processes, with JMS queues for consumption of Asynchronous requests.● Implemented light weight WADL (Web application description Language) for better understanding of Rest based web services and its configuration.● Used multithreading for writing the collector parser and distributor process, which was getting real-time data from Zacks API in format of JSON, using multithreading improved the performance by a lot. Moreover, using concurrency package of collections made it thread safe.● Used SOAPUI to test for sending and receiving XML data and worked with JMS Queues for sending messages in point to point mode communication.● Performed unit testing using JUNIT framework and tested DAO's and Business Services● Provide 24x7 support to the application in pilot and production phases. Support included being on conference calls, identifying and fixing bugs, investigating reasons for specific application behavior.● Written complex SQL queries, Stored Procedures and Functions in PL/SQL for manipulating the data.● Developed Servlets for server-side transactions and made use of AJAX for server-side processing without refreshing the JSP page.● Used AJAX and JavaScript for Client-side validations.● Created Web User Interface (UI) using HTML5, DHTML, table-less XHTML, CSS3 and Java Script that follows W3C Web Standards and are browser compatible.● Used HTML5 wireframes with CSS provided by the design team. JS is used to make it dynamic● Used JavaScript, HTML, JSP pages for developing front end UI and wrote application level code to perform client-side validation.

● Java message queue (JMS) is used for exchanging information and messaging services.● Developed SOAP web services (JAX-WS) for sending and getting data from different applications WSDL generation and exposed the service at server-side.● Developed and implemented the MVC architectural pattern using Struts Framework including JSP, Servlets and Action classes.● Designed and integrated the full-scale Struts/Hibernate persistence solution with the application architectures.● Developed DAO pattern to retrieve the data from the database.● Database and Implementation skills with ORM frameworks Implementation skills with ORM frameworks like Hibernate and MyBatis● Build and maintain SQL scripts, indexes, and complex queries for data analysis and extraction.● Created many Stored procedures and scheduled jobs to support our applications to create reports for customers.● Created PL/SQL procedures, functions and written complex SQL queries for C2C resume builder● Worked with the QA team to solve the issues related to the development.● Involved in system integration and solved the production issues.● Used JavaScript and jQuery for validating the input given to the user interface.● Used jQuery to build accordion style content, drag and drop functionality, calendar, popup and modal windows.● Performed many DOM manipulations using Native JS and jQuery for loading and manipulating dynamic content on webpages.● Used BackboneJS for creating responsive UI modules with hardcoded dependency of Underscore JS in combination with Handlebar JS for templating.● Used Backbone JS to utilize a minimal set of data-structuring and user interface primitives for building a MVC workflow design.● Worked on JSP, Servlets, Struts framework and production support issues of the existing applications.● For messaging, use Message Driven Beans for consumption of JMS.
