• As part of Walmart’s Item Setup team, we are building tools to setup merchant and supplier’s product data in company’s different resource tiers, which will further used by different online/in-store platforms.• Working with Java Reactive programming to ensure end-to-end asynchronous data streaming with backpressure.• Developing configurable workflow to achieve onboarding of new flow with json based config changes.• Integrated with Kafka for data stream processing as system is responsible to enrich and orchestrate more than 70 million events per day.• Using Spring boot framework, Cassandra for data integrity, Elastic Search to audit transactions, Splunk for logging, Kubernetes for automatic deployment and scaling, Maven as build tool.

APPLE• Working on a service based application where we are developing REST services using multiple internal service providers to manipulate customer data which is further used by the company's support team to resolve the customer issue.• Integrated complex algorithms with Java to ensure code quality, performance, reusability with edge scenarios. • Worked on Generic Bulk framework using multithreading concepts to remove repetitive activity which helps to utilize time.• Efficiently Implemented Utility methods to handle/process generic data and failure.• Use of Spring Framework provides a comprehensive programming and configuration model for Java-based implementation. Which helps to make code more structured and reusable.• Sonarcube integration ensures continuous inspection of code quality to perform automatic reviews of code to detect bugs, code smells, and security vulnerabilities.• We are using Oracle database with MyBatis framework to maintain customer-advisor integrity and security.• Developing user interface using JQuery and JavaScript to make it dynamic and friendly. • Configured Log4j for logging, Gradle as build tool, Jenkins and rio to automate CICD pipeline.• We are using git as a version-control system to track changes in source code software development. Also build, sonarqube and a few other plugins in git helps us to maintain code quality.

• Working on data for future development and modification on algorithms based on trained data results.• Applying data mining/machine learning algorithms to available data in order to identify useful insights.• Implemented categorization of Dataset reviews into various Sentiments ("Positive", "Negative" and "Neutral") using various Machine Learning algorithms (Multiclass Classification) such as Naive Bayes classifier, Random Forest, Decision Trees Implemented Supervised learning techniques to predict the sentiment.

• Responsible for analysis, design, development, and integration of UI components with backend using J2EE technologies such as MVC framework, Servlets, JSP.• Used Hibernate for persistence logic, which consisted of creating XML mapping files for statics data and queries to gain quick access of static web pages.• Web project foundation includes presentation, security, data manipulation, efficiency and quality assurance.

• The Project consisted of designing and implementing a cloud-based mobile web application that delivers product updates on demand. • Extensively used Hibernate technology for development, ORM System for interacting with Oracle database.• Integrated the JSP pages with the controllers and updated the data with the beans.• Developed and Consumed SOAP-based Web Services using Web Services.• Our work to implement Web Service support for the application.
