Implemented Agile (Scrum) Methodology that includes daily scrum meeting with team, sprint planning and estimating the tasks for the user stories. • Involved in designing User Interface (UI) applications and professional web applications using JavaScript, AngularJS, Bootstrap, jQuery, HTML, DOM, XHTML, JSON and AJAX, React JS. • Built Single page web application using JavaScript Frameworks like Angular 7, Angular 8, ReactJS, JS. • Responsible for creating efficient design and developing User Interaction screens using HTML5, CSS3, JavaScript, Angular and Bootstrap. • Implemented flux pattern by using redux framework as a core dependency. • Working with Angular routers like UI router to establish routing between Nested html views. • Built different modules, controllers, templates, custom filters, and directives in Angular JS. • Used twitter Bootstrap for creating responsive web design for varying screen sizes and devices. • Used Angular 7 by consuming Restful web services. • Created TypeScript reusable components and services to consume REST API's using Component based architecture provided by AngularJS. • Written the Rest Services to get the data from NoSQL Cassandra collections in JSON format. • Developed functional modules in the Data Access Layer using Hibernate with IBM DB2 as the backend database. • Worked on generating the web service classes by using Service oriented architecture (SOA), WSDL, SOAP, Spring-WS.

Analysed requirements with the business team, and involved in design, development, and testing of the application. • Used J2EE, REST, and Spring Framework for developing the application. Implemented the persistence layer using Hibernate and configured Hibernate with spring to interact with the Cassandra Database from the DAO. • Strong Experience on Virtualization, Cloud Computing and Web Services. Performed Configuration, deployment and support of cloud services including Amazon Web Services (AWS), • Open stack and VMware. • Used Spring Rabbit-MQ in cluster as messaging system between the APIs and Micro services. • Strong Experience in Deploying, managing, and operating scalable, highly available, and fault tolerant systems in different Cloud providers. • Implemented Spring AOP for basic authentication at API Level, which it reduces the development time to handle the exceptions.3 • Extensive Experience with VMware, AWS API’S while developing the User Story’s. • Developed Spring REST web services to serve multiple applications across the organization. The data is provided in Json and used Jackson library. Also, consumed REST web services. • Good Experience in writing various SHELL Scripts to run on top of a virtual box in various Providers. • Implemented Microservices architecture using Spring Boot for making application smaller and independent. • Involved in J2EE Design Patterns such as Data Transfer Object (DTO), DAO, Value Object and Template.

Involved in various phases of Software Development Life Cycle (SDLC) such as requirements gathering, modelling, analysis, design, development, and testing • Designed User Interface using HTML, XHTML, CSS/CSS3, jQuery, JavaScript, AJAX, JSP and AngularJS and XML in a responsive grid layout. Implemented responsive design template to get a new interface in Bootstrap, HTML5. • Developed the view-controller components using Servlets/JSPs, JavaScript, jQuery, CSS, HTML and DHTML • Implemented routing logic and navigation from screen to screen and implemented login functionality on the client side in AngularJS. • Involved in Writing Object Relation Mapping implementation using hibernate and hibernate mapping and used Hibernate for mapping an object-oriented domain model to a traditional relational database. • Improved Insecure Direct Object References by mitigating the exposure of reference to an internal implementation object. • Created various MongoDB collections and wrote services to store and retrieve user data from for the application on devices and used Mongoose API in order to access the MongoDB from NodeJS. • Created Collections and documents and performed CRUD operations with Mongo repositories and developed ORM mappings using Hibernate and wrote Criteria, Named and HQL queries for data retrievals in the DAO layer • Utilized Amazon Web Services (AWS) EC2 to deploy Docker containers with both monolith and Microservice Architecture • Created a Lambda Deployment function and configured it to receive events from your S3 bucket. • Deployed AWS Lambda code from Amazon S3 buckets.
