Sr. Java Developer

• Developing high quality REST full API (End points) using spring boot frame work for many microservices such as contest, goal quest and elastic indexing management service.
• Strictly follow the REST API standards while developing API and do code review with team members before push to GIT.
• 100% make sure following TDD process because of its benefits, and do create many test scenarios so that functional failures would not occur.
• Developed REST API in generic way to index different type of participant data for elastic index management micro service which is used by global SEARCH-BOX.
• Write simple/complex elastic Search (NOSQL search engine) query to provide data to search box.
• Make sure exception handled in proper way and communicated to REST caller with proper http status code and message.
• Writing Junit, mockito and spock, and encourage/help others developers to write more scenario with good amount of code coverage.
• Develop java components using Java8 feature and make component more functional perspective instead of technical/boiler late view.
• Responsible to work with co-developer and do code reviews frequently and make sure all other code as well quality.
• Help junior developers in terms of technically or functionally to meet on time delivery.
• Interact with product owner and architect team to understand business and architectural design during sprint plan or whenever required.
• Create rest controller, service and JPA objects by following REST and SOLID standards and do code review for junior developer’s artifacts as well.
• Coordinate with QA resource and verify all acceptance tested before delivery.
• Co-operate with Devops team to make sure features goes smooth in to production.
• Use AWS EC2 Elastic search index instance to index participant information’s.
• Use AWS S3 to store participant video/image and other files.
