PROFESSIONAL EXPERIENCE:

Confidential, Seattle, WA

Java Developer

Responsibilities:

• Involved in the analysis, design, development and testing phases of Software Development Life Cycle (SDLC).
• Worked on two different teams under Social Activation and Social Commerce team of SMPD project.
• Under SMPD project worked always on Agile methodology. Used to has technical grooming almost in every 3 days, sprint closing in every two weeks. In sprint closing used to do demo by each team under SMPD. me personally participated and explained wat has been done, wat is our next target for another sprint.
• Used J2EE, REST and Spring BootFramework for developing the application and worked on JRE 1.8.
• Mostly used Spring MVC framework for developing of each services.
• Developed REST web services to serve multiple applications across the organization. Used Postman to make REST calls to see the efficiency of the methods written wifin each microservices. Used JSON payloads as the message to transfer between each microservices.
• Under SMPD, worked on both Twitter and Facebook’s APIs, and wrote services to receive direct messages from customers and passed those messages from microservices developed for social activation and social commerce architecture.
• Got some time to work parallelly wif other team working on Artificial Intelligence and big data.
• Has thorough understanding on creating webhooks for Twitter and Facebook APIs. Used Apigee to create URLS, which was used as a gateway to pass message between two applications.
• Created microservices to listen to direct messaging events from both Social platform users and wrote microservices to send response after passing messages between two ends of overall architecture.
• Spend high volume of time on creating architecture for SMPD’s social commerce project.
• One service where number of customer orders, also the states of customer selection and customer identification was needed to store, we used DynamoDB to store. Since the record stored wasn’t so heavy and looked use of DynamoDB looked not so effective but still we used.
• Used Kafka technology to drop messages from one microservice into one Kafka topic and receive it from another topic. In between two topics, the message is transferred and processed through another microservice.
• Wrote Unit tests for all services using Junit 4, Junit 5 and Mockito frameworks.
• Developed services using Spring Boot versions 1.5.4, 1.5.7, 1.5.10 and 2.0.3. Migrating from one version to another was a tedious task.
• Used Maven build tool to automate the build process and Jenkins as CICD tool.
• Used JIRA for bug tracking and raising tickets.
• Used Trello by each developer in the team to explain wat they are working on and wat is the progress based upon the Jira tickets they are assigned to.
• Used Atlassian Confluence page to discuss about the task and architecture between the team members.
• Developed Junit test cases for unit testing the application.
• Used Log4j libraries for logging and managing code base.
• Used GIT for version control.
• Used Bitbucket repositories to store the projects.
• Build and deployed the application on Tomcat Server and JBOSS server.
• While developing microservices created sequence diagrams using Plant UML plugins.
