Worked on Angular8 for developing dynamic web pages for the applicationDeveloped reusable Life Cycle HooksStrong utilization of Angular HTTP services to make REST API service calls for CRUD Operations from the SPA to the databases.Extensive use of Core Java concepts like Collections Framework, Exception Handling, I/O System, Multi-Threading, GenericsUsed java SE8 features like stream, lambda expressionsWorked with Spring Boot to manage relational data in Java applicationsManaged to use Spring DI and Auto wiring Annotations while implementing REST APIsUtilized Apache camel for connectivity, microservices,orchestrationsBuilt JAVA Spring batch service for data exchange and data manipulation of various databasesSpeeding development process using Design Patterns such as Singleton, Factory, Service Locator, and Business delegatorImmense use of SQL Concepts to define, manipulate and control data in MSSQL database. Used PL/SQL stored proceduresImplemented Swagger Configuration in java Spring Boot to autogenerate REST API documentation Developed JUnit test cases and used Mockito framework. Karma- Jasmine testing to test the User InterfaceEmployed SoapUI and Postman for validating and checking the response formats of REST ServicesUsed Kibana for logging and Bitbucket as code repository & version control toolUtilized Maven tool to build and inject the dependencies using project object model (POM) for executionJenkins was used to integrate, build, and deploy the applicationDeploy and maintain production environment using AWS EC2 instances and ECS with DockerDeveloped Java API to interact with the Amazon SQS used in sending bulk emails and for Amazon Lambda to manage some of the Amazon Web ServiceEmployed Splunk across the organization to access machine data

Extensive use of technologies like CSS3, HTML, ReactJS and Bootstrap for building highly interactive well-designed presentation layer and Graphical User Interface (GUI). Strong use of ReactJS to develop multiple screensDevelop custom UI components for data manipulations and display data according to the client requirements and standards on their UI using ReactJS and Redux with ECMAScript. Extensively used Core Java concepts like Polymorphism, Inheritance, Enumeration Streams and File I/O in logic design and development. Employed Java 8 features and implemented design patterns like Singleton, Business Delegator,Factory, Service Locator. Used Spring Boot JPA to access and persist data between Java Object/Class and relational databases by following the Object-Oriented Mapping (ORM). Utilized ORMs EntityManager API to process queries and transactions on the objects against the database using Java Persistent Query Language (JPQL). Used Spring Boot Actuator to expose operational information about running the application and using HTTP endpoints to enable us to interact with it. Achieved high security of the REST API's by using Spring Boot security. Built web services using a microservice architecture with spring boot.Used Mongo DB to store data as collections and documents in JSON format. Project management using JIRA for bug trackingEmployed MAVEN tool to build project.Focused on Test Driven DevelopmentUsed JUnit to write test cases for Controller, Service & DAO layer and used Mockito framework to confirm the expected results. Also, unit tested client-side code built using REACT with Jasmine. Worked in AWS environment, involved in utilizing Compute Services (EC2, ELB), Storage Services (S3, Glacier, Block Storage, Lifecycle Management policies), VPC,RDS, Lambda, and Cloud Watch. Worked with Splunk for analyzing log files and creating queries to explore events and report on any API failures.

Involved in Object Oriented Analysis and Design (OOAD) and documentation of the application model using UML. Involved in component development and used design patterns such as Singleton,Factory and Facade.Designed and developed interactive static HTML screens, JavaScript , used CSS and Bootstrap for animation and graphic implementation. Developed JSP custom tags and used JSTL for reusability. Worked on Components, Directives, Services, Forms, Http Access, Authentication, optimizing an internal application using Angular with Modules and Offline Compilation. Implemented features such as routing, data binding, data updates without a page refresh using Angular. Created TypeScript reusable components and services to consume REST API's using component-based architecture provided by Angular and used Angular Http services to display the content on the browser. Worked with Core Java concepts like Encapsulation, Data Abstraction and Inheritance and used data structures like HashMap, and Sets. Participated in development of the application using components of the Spring Framework. Also implemented Dependency Injection using the spring framework. Implemented Spring MVC architecture for web application development using Spring, JSP (Java Servlet Pages) & Java beans to migrate from Struts Framework. Used Spring Context for EJB Support and Spring DAO for enhanced JDBC and DAO support. Immense use of SQL Concepts to control data in MYSQL database. Developed Triggers and Stored Procedures with use of PL/SQL to implement the business logic. Used Eclipse IDE for development, configured and deployed the application on to WebSphere using Maven, for version control & code repository purposes used SVN. Employed Jenkins to automate software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. Used Apache Tomcat as a web server and WebLogic as an application server to deploy various components of application.
