• Development of new EPA Application to process huge files coming from the clients and processing them in an asynchronously using queues. Increasing the performance of the application by managing the resources when it is required.• Design and development of Reports-Engine to process multiple reports generated by the client. Every report generated by the client will be sent to the client specific queue and a new EC2 Instance will start whenever there is a message in the queue. Once the message is processed and if there are no more messages in the queue the instance will shutdown.• Development of Angular-5 UI Module for Report-runner.

• Involved in SDLC requirements gathering, analysis, design, development and testing of application, developed using AGILE/Scrum¬¬ methodology.• Utilized Java 1.8 features like Lambda expressions for collection evaluation and comparing the data, Stream API for Bulk data operations on Collections, which would increase the performance of the Application, Parallel operations on collections for effective sorting mechanisms and to change the sequential stream flow of threads while session establishment.• Created single Page Application with loading multiple views using route services and adding more users experience to make dynamic by using Angular 4 framework and Node JS.• Implemented Angular 4 component router for navigation and the services to connect the web application to back-end APIs.• Used React JS to create views to hook up models to the DOM and synchronize data with server as a Single Page Application (SPA) and React-Redux thunk to make REST API calls. • Ported and redesigned the Lead management system using Angular2, implementing modular design.• Involved in the user interface implementation for various screens of the application using java swings.• Strong MySQL and MongoDB administration skills in Unix, Linux and Windows.• Developed Rest Api to processes the data from DB to another Rest Service.• Worked on AWS, High Availability Practices and deploying backup/restore infrastructure.• Involved in building COSMOS web services test application.• Worked in using React JS components, Forms, Events, Keys, Router, Animations and Flux concept.• Designed and Developed the Monitoring and commanding capability in the Java Swing UI using the common Swing components.• To get AJAX functionality for the website wrote JavaScript and jQuery programming.• Coded web services to expose Oracle DB Functions and Store procedures.• Connected to Data sources and performed operations using Spring Data Framework features like Spring JDBC and Spring ORM.

• Worked in a highly dynamic AGILE environment and participated in scrum and sprint meetings.• Extensively used Java 8 features such as lambda expressions, Parallel operations on collections, multithreading and for effective sorting mechanisms and Streams to store and process the data.• Designed and Developed the Monitoring and commanding capability in the Java Swing UI using the common Swing components.• Implemented Multithreading concept to handle transaction management with isolation and propagation levels.• Designed the system based on spring MVC Model architecture. Developed a business logic layer using spring Dependency Injection and client-side Java-beans for DAO Design Patterns. • Created internal dashboards, alerts, and scheduled reports to monitor overall Splunk performance. On boarded new data into a multi-tiered Splunk environment. • Designed and developed components relating to Concept Wave projects.• Created and updated database objects in Concept Wave frameworks.• Developed Spring boot application with microservices and deployed it into AWS using EC2 instances. • Involved with migration of AI-based project from Google Cloud Platform into AWS.• Design and manage API system deployment using a fast HTTP server and Amazon AWS architecture.• Developed dashboards to monitor druid cluster health using InfluxDb, and Kafka. • Created Stream Rest based Application interfaces on java 8 environment.

• Involved in various phases of Software Development Life Cycle (SDLC) of the application like Requirement gathering, Design, Analysis and Code development.• Used MongoDB to store Big Data in JSON format and Aggregation is used in MongoDB to Match, Sort and Group operation. • Developed UI component with AngularJS framework by utilizing the core features like MVC pattern and Dependency Injection.• Developed the back-end web services and designed the front end of the application using CSS, AJAX, JSON, Drupal and JQuery.• Used collections in Java for manipulating and looping through different user defined objects.• Used Multithreading to improve the performance for processing of data feeds.• Implemented Angular JS Data Binding capability in HTML5 to give user a rich and responsive experience.• Used jQuery to modify DOM elements content by using cross-browser selector engine called Sizzle.• Developed and implemented the MVC Architectural Pattern using Spring Framework and used Spring IOC container to maintain core Objects Lifecycle.• Implemented test driven development (TDD), executed unit test plans and Grails Spock Test cases for all existing controllers, Services and Domain classes and Grails Pagination to display data using Grails Templates and views.• Implemented Spring Security for user authentication, limit login attempts and password hashing.• Developed Web Services (SOAP) using Spring-WS to handle user requests and interact with other components.• Developed Microservices using Spring Boot and Spring Batch, that create, update, delete and get the assignment information from backend.• Implemented Spring Boot Microservices to divide the application into various sub modules.• Created application on Spring Batch framework and Multithreading to improve performance. Used Multithreading for faster and parallel processing of documents.
