PROFESSIONAL EXPERIENCE:

Confidential, Santa Clara, CA

Sr. Software Developer

Responsibilities:

• Responsible for production support, developing in-house automation framework, and Jenkins Continuous
• Integration and build and deployment.
• Implemented Hibernate, Spring - Core/Security/AOP.
• Worked on a POC project using SPRING BOOT.
• Developed Web Services using REST. Worked both on Service and Client Side (produced and consumed).
• Deployed and tested web services using POSTMAN/SoapUI.
• Setup a Jenkins CI server and integrated it with various automation frameworks - in-house Java Automation
• Framework (for server admin console), Krypton (client side devices testing), SoapUI (web services) and python tests.
• Worked extensively on Linux machines.
• Developed a lot of UML diagrams and architectural documents for legacy code.
• Wrote JUnit tests to test all implementations. Set up code coverage tool for web applications to monitor the degree of source code being tested in different environments.
• Supported the application in production and worked on the incidents in a timely manner.
• Demonstrated the application to the end users during scrum meetings and at the end of the release.
• Involved in resolving business and technical issues.
• Supported maintenance team after deployment.
• Resolved the productivity bottleneck that many developers faced as far as deploying the code locally. They used to deploy the code on Virtual Machines making debugging very painful.

Environment: Core Java - Algorithms & data structures, J2EE/JEE, Spring (MVC, Core, DAO, ORM Hibernate, AOP, Security), Spring Boot, Hibernate, REST Web services, Cloud - AWS and Azure, Jersey, JSP, XML, JSON, Ajax, JavaScript, log4j, Gradle, Jenkins, Perforce then GIT (Bit Bucket), JUnit, Tomcat Application Server, PostgreSQL, MS SQL & MySQL, Waterfall then migrated to Agile, IntelliJ IDE.

• Developed White box test cases using JUnit and Mockito frameworks and Configured Log4j Mechanism for complete project using xml files.
• Create Maven pom.xml files and integrated with Jenkins CI. Worked closely with build engineers
• Wrote stored procedures and inner joins using RDBMS MS SQL on Unix and Windows environment
• Designed the application using UML, Class Diagrams, Sequence diagrams and State diagrams.
• Wrote JUnit tests to test all implementations. Set up code coverage tool for web applications to monitor the degree of source code being tested in different environments.
• Coordinated the efforts across several teams to ensure smooth progress of migration and to resolve any issues. Worked very closely with end users.
