PROFESSIONAL EXPERIENCE

Confidential - San Francisco, CA

Java software engineer

Responsibilities:

• It is an Agile based project. Had daily stand up meetings, retrospectives and sprint grooming etc.
• Gather requirements, analyze, write maintainable code and document it. dis project used Java 8 as teh core programming language and Spring as a dependency framework.
• For better code analysis and detecting bug we used SonarQube as a static code analyzer to protect application for malicious attacks and detect bugs beforehand.
• Implemented unit test cases wif Junit, testing teh web layer wif Spring Test runner and generating code coverage report wif Jacoco resulting in better and maintainable code.
• Leveraging power of Gradle build tool for faster build process and custom dependency scopes.
• Migrated SpringBoot based project to Jax-RS Jersey project wif JAVAX Autantication/Security mechanism.
• Used OAuth to as an Autantication protocol and migrating to JWT (to avoid sticky session) as teh application would be deployed to cloud down teh line.
• Teh back end or teh data feed of our application is GOOGLE APIGEE. We use teh end points from teh same by looking over teh documentation and policies that are provided by APIGEE.
• Logging is teh main aspect of any web application. We used Log-back(logback) to log and store teh logs on Splunk for centralized access.
• Teh front end of dis application is based on React JS and has good exposure on teh same. Used both JSP and Spring rest for URL redirection and returning JSON responses.
• Design develops and tests HTML5, CSS3, Bootstrap, JavaScript, jQuery, and React.JS that meets accessibility and web browser standards for teh website.
• Designed CSS templates for use in all pages on teh website working wif CSS Background, positioning, text, border, margin, padding, and table.
• Experienced implementing Jersey in MVC architecture while utilizing React features.
• Application is deployed on Tomcat container and used Jenkins as CICD tool.
• Worked wif SASS which is a CSS pre-processor and wrote CSS using SASS variables, mixins and nesting feature.
• Written Unit test cases using Jest, End to End test case using Cypress and Enzyme to improve code quality and coverage.
• Worked on React JS Virtual Dom and React views, rendering using components that contain additional components called custom HTML tags.
