Strong experience with Microservices, Spring Boot, Spring Cloud, Cloud Foundry. Proven ability in developing BDD scripts with Cucumber and writing step definitions for behavior.

Experience in Automation testing using Selenium Web Driver, JUnit, and Maven. And Used Apache Kafka (Message Queues) for reliable and asynchronous exchange of important information between multiple business applications.

Involved in developing an automation tool, in Java and Scala on Kafka Framework. And Responsible for overall Docker &Kubernetes setup, configuration, and Architecture. Configured and maintained a large-scale Docker based PaaS environment using Kubernetes.

Used React JS and Node JS to develop faster, scalable application.

Implemented various screens for the front end using Reactjs and used various predefined components from redux library.

Using Angular JS factory and services for dependency injection and created custom directives for re-usable components (multi-field form elements, background file uploads, etc.)

The application is based on Micro Service Oriented Architecture using Angular 4.0 and Cassandra DB and MySQL to develop Single Page Applications (SPA).

Implemented Angular 4.0 directives, expressions, routing capabilities for bookmarking, filters, validations and Angular UI components, Components, ng-Modules, Providers, Services, and classes for navigation, respectively.

Worked with Angular CLI and Typescript in Angular 4.0 to create Controllers and Angular components for the Web Pages.

Used spring framework and J2EE components, Utilized Spring Boot, IOC, and DAO modules. Developed controller classes, backend process, complex services, and database interaction.

Used Spring Boot to create stand-alone spring applications. Created Typescript reusable components and services to consume REST API's using Component based architecture provided by Angular 4.

Implemented Micro Services based Cloud Architecture using Spring Boot and implementation of Business Services using the Java8 and Spring Boot.

Used Spring Boot framework to write Presentation Layer, Business Layers and Controller servlets. Implemented Spring Boot Actuator to monitor application performance And Used Spring Inheritance to develop beans from already developed parent beans.

Used Spring Cloud Config which provides server and client-side support for externalized configuration in a distributed system. And Used Java Messaging Services (JMS) which provides reliable and asynchronous form of communication and have good knowledge in RabbitMQ.

Implemented Service Oriented Architecture (SOA) by invoking multiple SOAP based Web Services and generating client using JAX-WS. Used SOAP UI to interact with other applications using SOAP and WSDL file. Also involved in creating the Hibernate POJO Objects and mapped using Hibernate Annotations.

Integrated spring with Hibernate using configurations and implemented DAO layer to save entities into data base. Used Kubernetes to configure in the application for automating deployment, scaling, and management of containerized applications.

Used Rest templates in the Spring Services to call the rest web services. And Used Hibernate, object relational-mapping (ORM) solution, technique of mapping data representation from MVC model to Oracle Relational data model with a SQL-based schema. And Used Microservices architecture with spring-boot based services interacting through a combination of REST and RabbitMQ

Involved in writing Oracle PL/SQL Stored procedures, triggers, and views. Worked on NoSQL data base MongoDB& Performed CRUD operations like Update, Insert & Delete.
