Developed end to end microservice following TDD and BDD using spring boot, hibernate validator, JAX- RS and built docker container and deployed to AWS ECS container.Worked with AWS services such as EC2 , S3 , Elastic Container Service , Elastic Load Balancer , IAM , Lambdas , AWS Rest API .Developed server-side components by modularizing into controller, service and data access layers following REST Microservices architecture involving POST/PUT/GET/DELETE HTTP methods.Hands on experience in developing complete server components like serializing/ deserializing form/response elements into/from JSON body and communicating with vendor services or/and database layer.Implemented Spring MVC framework in the application. Developed code for obtaining bean referencesin spring framework using Dependency Injection ( DI ) and spring IOC.Designed Spring Controller to handle requests from users and return results, spring security for securing URL access and authorization using OAuth 2.0.Implemented federated SSO using ping identity that permits a user to use one set of login credentials.Developed java batch application that gather analyst notes from MongoDB a NoSQL database, filter it and store it into the MsSQL database.Created complex but optimized SQL and PostgreSQL queries to improve database performance and memory management.Designed and implemented page data submission features within single page and rich client UI using Angular 2.0, HTML5 , CSS3 and JavaScript .Implemented jQuery AJAX calls in web pages to render the JSON response on to UI.Worked in an Agile work environment and used SVN , Git and bitbucket as version control and Jenkins and Bamboo for continuous build integration.Developed test cases and performed unit test using JUnit Framework in a TDD and used Bugzilla for bugs and issues tracking.

• Followed Agile methodology for developing application and involved in analysis, design, development, and testing phases of Software Development Life Cycle.• Designed and developed Microservices using REST framework and Spring Boot and used Bootstrap along with Angular 6 in creating the Application.• Used front-end technologies HTML5, CSS3, JavaScript for interacting with the user interface and built components for the robust front-end Single Page Application built on Angular 2.• Created Menus and Drawer component by using Typescript and Angular JS.• Implemented Angular 2 Router to enable navigation from one view to another.• Used the latest HTML5 elements for video playback, content rendering using semantic tags such as• article, section etc.• Developed basic reusable form fields like text, radio, select, typeheads and buttons using Angular 6.• Created UI pages using JavaScript, AJAX, jQuery, Bootstrap, HTML5, DHTML, CSS3 with npm modules by given wireframes.• Developed various generic JavaScript functions used for validations.• Used Hibernate 4.2 framework as the Object Relational Mapping tool for persisting java objects on Oracle 12c Database.• Used Microservices to build individual components of the application and built the application on Spring 4.x Framework.• Implemented Spring MVC flow to interact with different modules of the application.• Built and consumed RESTful services in modules and implemented serialization using Spring REST and JSON. Designed and developed the REST based Microservices using the Spring Boot, Spring Data JPA.• Designed and developed custom message adapter components using Apache Kafka that allowed the message to travel through Microservices to base on Restful API utilizing Spring Boot with Spring MVC.• Used Spring AOP to maintain the code clean and logic consistent and used pointcuts to call other classes methods accordingly.• Created high level functional flow diagrams using Microsoft Visio.
