I contributed to the development of secure, scalable payment processing services supporting millions of daily transactions in a fast-paced Agile environment. I designed and deployed Java/Spring Boot microservices on Tomcat and WebSphere, implemented and secured RESTful and GraphQL APIs with Spring Security, OAuth2, and JWT, and optimized SQL/NoSQL data models to improve performance by 35%. I enhanced the checkout experience by building real-time update channels with SSE and WebSockets, integrated fraud detection modules with caching and algorithm tuning that reduced latency by 25%, and partnered with data teams to streamline real-time fraud detection pipelines. On the frontend, I built responsive React.js dashboards for merchant onboarding and product configuration, delivering reusable UI components and improving user engagement. I also strengthened cloud adoption by containerizing and deploying services on Azure Kubernetes clusters, implemented ElasticSearch for real-time search, and supported legacy integration with SOAP/JAX-WS services. Additionally, I enhanced CI/CD pipelines with Jenkins and GitHub Actions, monitored high-volume traffic using Splunk dashboards, and applied Oracle RMAN/Data Guard strategies to safeguard mission-critical transaction data.
