Followed iterative application improvement determined by Agile Scrum procedure comprising of week after week Sprints and stand up gatherings and fabricated the application with Test Driven Development (TDD).Designed the framework in view of Spring MVC Model design. Built up a business rationale layer utilizing Spring Dependency Injection and customer side Java-beans for DAO Design Patterns.Designing n tier enterprise applications with J2EE design patterns like IOC (Inversion of Control), AOP, MVC, Business, Delegate, Front Controller, Factory, and Singleton.Skilled in using collections in Python for manipulating and looping through different user defined objects.Involved in developing a video calling application using python web-sockets.Exposure to automation in Ansible using its Python API.Building and supporting libraries in the test automation infrastructure.Developed micro apps with latest Angular 8. Micro apps are easy maintainable and highly reusable.Experience with Angular 4 Directives, Dependency Injection, Services, Routing, pipes, Animations, Forms, AOT, Lazy Loading, RXJSCreated Typescript reusable components and services to consume REST API's using Component based architecture provided by Angular 4.Worked on Angular 5 Modular Programming.

Involved in the examination, outline, and improvement and testing periods of Software Development Lifecycle (SDLC).Followed Agile Scrum Methodology in break down, characterize, and report the application which will bolster useful and business prerequisites.Involved in developing Use case diagrams, Class diagrams, Sequence diagrams and process flow diagrams for the modules using UML and Rational Rose.Worked on Distributed Web Services/ Enterprise / Web / Client- Server systems using Java, J2EE (JSP, Servlets,JDBC, EJB, JNDI, JMS, JAXP, JAXB, SDO, JPA), XML, kafkaWeb services, ESB, JINI and Java Spaces Technology.Developed the presentation layer using JSP, AJAX, HTML, XHTML, CSS and client validations using JavaScript.Developed Client-side code in Angular JS, integrated with REST, processed the JSON response successfully performed the RESTful APIs Integration and developed an API wrapper for reusability.Used RESTful web services producer and consumer concepts to build this API as a micro Service. Developed and implemented the MVC Architectural Pattern using Spring Framework.Effective usage of J2EE Design Patterns Namely Session Facade, Factory Method, Command, and Singleton to develop various base framework components in the application.Modified Account View functionality to enable display of blocked accounts details that have tags. This involved modifying beans, JSP changes, and middle tier enhancements. Developed various EJBs (session and entity beans) for handling business logic. Developed Session Beans and DAO classes for Accounts and other Modules. Involved in writing application Context XML file that contains declarations and another dependent Object’s declaration.Unit testing.Implemented Angular6/7 to develop front end of the web application.Agile/Scrum was used as the project management methodology, JIRA & Confluence were the tools used to keep things tracked.

• Developed a custom single page application using AngularJS and created services, factories, models, controllers, views. • Used Hibernate for Object Relational Mapping (ORM) and data persistence.• Designed and developed the REST based Microservices using the Spring Boot. • Used Oracle 10g as the back-end database to store the data. • Expertise in coding optimized SQL queries on databases like DB2 and Oracle. • Developed components utilizing spring framework modules (IOC, AOP, MVC etc.). • Integrated Spring with Hibernate and made as Spring bean using Hibernate Template. • Used Spring AOP to handle transactions session aspects and to implement security. • Designed and created DAO using data modelling in the integration layer. • Used Hibernate as the ORM mapping tool and worked with Hibernate Query Language (HQL). • Created RESTful Web service for updating customer data from sent from external systems. • Designing the database schema, creating tables and views and writing stored procedures, functions and queries in SQL.
