As a Software Developer at PayPal, I design and deploy Java Spring Boot microservices and REST APIs to power checkout flows, improving API latency by 15%. I built a unified JavaScript SDK that reduced merchant onboarding time by 20% and integrated fraud detection APIs to cut fraud attempts by 12%. I also optimize checkout performance with React.js, Node.js, and manage Docker/Kubernetes deployments, ensuring 99.9% uptime. Additionally, I enhanced merchant dashboards with real-time analytics (React, GraphQL, PostgreSQL) and supported PCI DSS compliance for international expansion.

At Cognizant, I built full-stack applications using Java, Spring Boot, ReactJS, and Hibernate, improving claims and policy management systems. I migrated workloads to AWS (Lambda, EC2, S3) for scalability, cutting costs, and automated deployments with CI/CD pipelines (Jenkins, GitHub Actions, Docker), reducing release cycles by 40%. I also ensured quality with TDD/BDD practices and robust testing frameworks like Jest, Mocha, and Cypress.

At Wipro, I worked as a Software Engineer developing a high-traffic e-commerce platform using Node.js and Spring Boot. I built real-time inventory management features that reduced stockouts by 25% and implemented Redis caching to improve API performance by 40%. I also integrated secure payment gateways ensuring PCI DSS compliance, optimized MongoDB queries for faster response times, and automated deployments through Jenkins CI/CD pipelines to streamline releases and enhance reliability.
