• Designed and developed microservices based applications using Spring Integration and Spring Boot framework• Used Fannie Mae Angular Development Kit to download or upload data in our back-end applications for communicating with these servers over the HTTP protocol this includes implementing a two-way data binding for enabling the ngModel directive upon Forms Module in angular/forms package.• Designed and implemented the REST Api for the UI screen through which the user can look-up the available plans and monthly charges against each of them by taking the user ID as the parameter.• Designed and implemented AWS Solutions using EC2, S3, EBS, Elastic Load balancer (ELB), VPC, Amazon RDS, CloudFormation, Amazon SQS and other services of the AWS infrastructure.• Behavior-Driven Development (BDD) implementation with Cucumber gherkin and Jenkins Continuous Integration, expanded test scenarios, tracked cucumber reports.• Implemented Kafka producer and consumer applications on Kafka cluster setup with help of Zookeeper and implemented to reprocess the failure messages in Kafka using offset id.• Performed dependency injection of spring beans such as data source beans or Hibernate utility singleton bean to create one session factory for the entire application.• Used MongoDB document-oriented database to store data and configured Mongo Sharding for scalability and High availability.• Used Splunk for log analysis.• Used Dynatrace for application performance monitoring to optimize and identify performance bottlenecks in web applications.• Implemented AWS High-Availability using AWS Elastic Load Balancing (ELB), which performed a balance across instances in multiple Availability Zones.

Involved in all the phases of SDLC and responsible for object-oriented design and worked closely with the business analyst’s in gathering, understanding and implementing the requirements.• Developed applications in Spring boot and used Java 8 features and other helpful libraries.• Designed and developed RESTful Microservices using Spring Boot for the application to seamlessly integrate with supporting subsystems.• Used Java 8 features includes lambda expressions, Parallel operations on collections, multithreading and for effective sorting mechanisms and streams to store and process the data. • Enhanced application performance by Angular 8 Component based development in view of future Angular framework transitions.• Experience with creating custom directives, decorators, and services to interface with both restful and SOA services.• Implemented Angular Router to enable navigation from one view to the next as customer performs application tasks.• Used various Angular 8 custom directives and developed reusable components and templates that can be re-used at various places in the application.• Worked with Angular 8 to develop single page applications, worked with ngrx for managing Angular applications.• Created Typescript reusable components and services to consume REST API's using Component-based architecture provided by Angular 8.• Migrated an application developed in Angular 8.0 to Angular 10.0 recently.• Designed and developed multiple REST services to be consumed by the front-end part of application.Good working experience with PostgreSQL database and written reusable functions, complex SQL queries and sub-queries.• Worked with Hibernate and JPA as a data access layer for PostgreSQL database. Good knowledge in writing JPQL queries.

Worked with Agile methodology and actively participated in Scrum meetings as a part of SDLC, to produce quality deliverables within time.➢ Develop the UI component architecture for developer framework using Angular 8, Typescript, HTML5, CSS3 and Bootstrap.➢ Created custom, self-contained, reusable and testable Angular 8 modules, controllers, directives and services to implement key functionalities for customer account summary.➢ Used Angular 4 Http services for asynchronous validations for the input fields of the forms with the data existed in the database.➢ Took part in setting up the routing configuration using Angular 8 router for various views and sub views.➢ Worked simultaneously in both production and development teams and took part in designing and developing dynamic web pages using HTML5, CSS3, Bootstrap, SASS, JavaScript, jQuery, Angular 8 for single page applications.➢ Worked on customizing the Bootstrap classes using CSS preprocesses like SASS.➢ Worked on the enhancements of the navigation and menu button into responsive features using Bootstrap Nav-default class and Collapse button.➢ Used AJAX calls to consume RESTful web services to fetch data and implement asynchronous communication with server side and then rendered the data on PrimeNG datatables.➢ Worked on creating Angular custom pipes to sort the history of various customers through order of date, year and month, ngFor for display of the history of customer details in tables.➢ Used Hibernate 4 to store the persistent data as an Object-Relational Mapping (ORM) took for communicating with database.
