PROFESSIONAL EXPERIENCE

Senior Java Developer/Technical Lead

Confidential - Northbrook, Illinois

Responsibilities:

• Analyzed, identified, and designed the microservices in the new architecture. Adopted domain - driven design approach for the microservice architecture.
• Involved in design of Restful APIs using Swagger and used WSO2 API manager to publish and manage APIs. Used Swagger UI for testing the services. Provided JSON request and response format to support various service clients.
• Developed Microservices using Spring Boot to interact with the backend systems. Used Spring Data JPA which provides a layer on top of JPA and used its CRUD repository methods, JPA specifications and Criteria API.
• Externalized all configurations of the application using Spring Cloud Config. Used Consul for Service registry and discovery, Zuul as the API gateway and Spring boot admin for monitoring the services.
• Used Spring Cloud Stream to publish messages to Rabbit MQ from upstream systems and implemented listeners to consume the messages and call downstream systems.
• Implementation of Hystrix circuit breaker to avoid loss of messages during handling of messages at the consumer level.
• Implemented and coded asynchronous business task using java Multithreading.
• Developed web analytics using Elastic Search, Logstash and Kibana. Built custom dashboards with Kibana to visualize aspects of data that are important to business.
• Used Confidential GitLab as source code repository and version control, Jenkins for Continuous Integration and Deployment.
• Developed Regression Test Suite using Cucumber and Rest Assured, and strictly adhered to the ATDD test practices.
• Involved in defining and modeling processes with JBPM for workflow automation in order to improve the efficiency of our intake processes. Used the GUI designer to draw process diagrams, created system and user tasks. Created Business services to invoke BPM process.
• Participated in performance tuning the application with jprofiler.
• Designed a backend system to process Business Events from various applications. These events can then be fetched and used for reporting/productivity monitoring.
• Leading and mentoring team members in achieving project time lines, helping them to produce quality code based on Confidential standards and providing technical solutions to critical issues. Also involved in doing code reviews for team members.
