   Jul 2023 — Present · Chicago, IL, US

   As a Sr. Full Stack Developer at Discover Financial, I contributed to the development of a secure, scalable Digital Credit Card Management and Transaction Intelligence platform used by millions of customers. I built modern front-end interfaces using React.js, Redux, Next.js, and Angular, and implemented complex state management with React Hooks and Context API. I enhanced performance with techniques like lazy loading, throttling, code splitting, and memoization, while ensuring cross-browser compatibility and responsiveness. I integrated real-time features using WebSockets, Kafka, RabbitMQ, and Server-Sent Events (SSE), and delivered robust, tested code through tools like Jest, Mocha, Cypress, and Karma. On the back end, I built microservices and APIs using Node.js (Express), Java 17, and Spring Boot, implementing secure authentication via JWT and OAuth2. I worked with MongoDB, MySQL, PostgreSQL, and DynamoDB, optimizing queries and using ORMs like Mongoose and Sequelize. I deployed scalable serverless services using AWS Lambda, API Gateway, and ECS, and managed CI/CD pipelines with Jenkins, Docker, and Kubernetes. I ensured code quality with SonarQube, followed Agile practices with JIRA, and monitored systems using AWS CloudWatch and Swagger. This role deepened my experience in real-time systems, secure API design, and enterprise-scale full stack development in a high-availability fintech environment.
