J2EE Developer

Responsibilities:

• Involved in analysis, specification, design, implementation phases of Software Development Life Cycle (SDLC) for developing application.
• Refactored existing monolithic application to Micro- services architecture, with Spring Boot-based services interacting through a combination of REST.
• Worked on Lambda Expressions, Functional interfaces Stream API's, Time API, and Improvements on Collection, Concurrency, and IO improvements by using Java 8.
• Developed Microservices with Spring Eureka to retrieve API routes for the entire cluster. Using this strategy each Microservice in a cluster can be load balanced and exposed through one API gateway.
• Developed AWS Lambda Functions in a stateless style and ensure there is no affinity between and compute infrastructure to manage the servers and run the code in the AWS.
• Developed Aspects using Spring AOP to implement logging, auditing, and error handling.
• Implemented functionalities by Spring MVC Controllers, configured with Spring annotations and configuration files.
• Implemented RESTful and SOAP based web services using for JAX-RS and JAX-WS respectively.
