Involved in Documenting (analysis, specification, design), implementing and testing phases of Full Software Development Life Cycle (SDLC).Implemented the persistence layer using Hibernate and configured Hibernate with spring to interact with the Cassandra Database from the DAO. Worked on Virtualization, Cloud Computing and Web Services. Performed Configuration, deployment and support of cloud services including Amazon Web Services (AWS), Open stack and VMware. Converted a monolithic app to microservices architecture using Spring Boot using 12 factor app methodology. Deployed, Scaled, Configured, wrote manifest file for various Microservices in Pivotal Cloud Foundry (PCF). Designed and developed Micro Services that are highly scalable, fault-tolerant using Spring Boot. Worked on deploying, managing, and operating scalable, highly available, and fault tolerant systems in different Cloud providers. Used Spring Core and Spring Data modules in Spring MVC framework for implementing Model-View- Controller (MVC) architecture at the Web tier level to isolate each layer of the application so that complexity of integration will be reduced, and maintenance will be very easy. Implemented Spring AOP for basic authentication at API Level, which it reduces the development time to handle the exceptions. Experience in implementing own OAuth2 Server to obtain Single Sign On and securing the URLs.Deployed Spring Boot based Microservices Docker and Amazon EC2 container using AWS admin console.Developed Spring REST web services to serve multiple applications across the organization. Developed user interfaces which are single page applications using JavaScript, CSS, HTML, Angular 6. Worked on multiple databases including MySQL, Mongo DB, and Cassandra. Schema design and deployment for both RDBMS and NOSQL databases.
