Java developer (kafka, REST api, swagger) | Hybrid
Nerdleveltech, Sunnyvale, CA, United States
Overview
Design, build and maintain REST API services using technologies such as Java, Spring, Hibernate, Tomcat and data stores to enable user interaction with large volume datasets. Build highly scalable, low latency, fault-tolerant, and high-performance architecture solutions for customer facing web and mobile applications. Participate in software development life cycle (SDLC) phases including sprint planning, estimating, design, development, testing, and deployment within an Agile development environment. Build customer facing software application features and platform libraries. Engage in end-to-end migration of back-end services and database platform from Oracle DB to Azure Cosmos DB. Leverage Reactive and Adaptive programming to handle change feeds from Azure Cosmos DB by creating robust reactive listeners and stored procedures. Build data communication between back-end systems using Kafka. Develop unit and automation testing frameworks, test suites, and stubs/mocks using Selenium, Mockito, JUnit, TestNG, Mocha, and Chai to thoroughly test software applications for all possible use case scenarios and achieve strong code quality. Troubleshooting open issues and bug-fixes. Enhance design to prevent re-occurrence of defects. Use JIRA for defect reporting and tracking. Run SonarQube on applications to measure continuous code quality by reporting code smells and vulnerabilities. Use Git version control for coordinating work with the team. Integrate applications with Jenkins to set up Continuous Integration and Continuous Delivery environments (CI/CD). Work on Splunk dashboard/queries to monitor application and system health and debug production issues. Use JMeter to load test software functional behavior and measure performance. Provide required demos to business stakeholders on software features and take required feedback for improvements. Provide inputs to relevant stakeholders for creation of project plans and ensure adherence to milestones and timelines.
