Scalable Web Application Development with Secure Authentication, API Integrations, and Cloud Deployment
We have developed multiple projects, with key projects focusing on backend services for scalable web applications. In one such project, we utilized Node.js with Express.js and a PostgreSQL database to manage user authentication, data processing, and API integrations. The backend included features such as secure JWT-based authentication, user profile management APIs, and integration with third-party payment gateways. We also implemented Redis caching to optimize frequently accessed data, ensured scalability through horizontal scaling and load balancing, and deployed the backend on AWS using Docker containers with Jenkins for continuous integration. Additionally, we developed a secure, scalable web platform using React, Node.js, and MongoDB, following an Agile methodology with bi-weekly sprints. The platform featured user authentication, content management, and real-time notifications. Key challenges included optimizing the platform for high traffic and integrating a third-party payment gateway. The platform was deployed on AWS, with Jenkins handling continuous integration, and all code was thoroughly tested using Jest and Mocha to ensure optimal performance and reliability.
