About Harsh Sinha

As an experienced Full Stack Engineer, I have worked on several complex and critical projects, building non-blocking reactive microservices using the latest technologies. My expertise lies in Java 11, Spring Boot, Spring Security, JWT, Apache Kafka, Microservices(Choreography Pattern), Spring Cloud Stream, ReactJs, Docker, and GCP GKE. I have collaborated with Software Architects to design Microservices and have implemented Choreography Saga Pattern with the help of Apache Kafka and Spring Cloud Stream to aid in building non-blocking reactive microservices. Additionally, I have implemented authorization within services using Spring Security and JSON Web Token for stateless session login, and developed Authorization service as an individual contributor. I am responsible for providing solutions to critical and complex business requirements, and have used the Strangler pattern to integrate services transforming into a microservice. I have also implemented non-blocking and reactive REST APIs in the account information services using Spring Boot and Spring Webflux, and worked alongside the UI team for migrating a multi-page UI to a single page React-Redux UI for Account information. In my previous position, I worked with the Product Development Team from inception to production for the development of a $45 million product, Mortgage Insurance Underwriting System(iQ+). I was responsible for developing REST APIs, collaborating with Technical Architects for providing Design Solution and Implementation, and developing GraphQL APIs for Loan Center(Third Party Application) integration. I have also implemented various APIs in the project in API Gateways and implemented Queue Producer and Listener on RabbitMQ to store Loan Documents in Alfresco and AWS S3. I have focused on functional programming approaches using Lambda expressions, Functional Interfaces, and Stream API to develop REST APIs, and automated unit test cases using Spring Boot Test, TestNG, and Mockito on Cucumber. I was responsible for delivering technological and functional KT's to my junior associates and delivered KT sessions on a new approach for Unit tests using Cucumber with SpringBootTest and TestNG. I am a dedicated and motivated professional with excellent communication skills, both written and verbal. I am always willing to learn new technologies and enjoy working in a team environment
