Designed and developed a fully responsive, production-ready full-stack website within 4 weeks, managing end-to-end implementation from UI design to backend architecture. Built the frontend using React and Next.js for optimized rendering (SSR/ISR), fast navigation, and SEO performance, while the backend was powered by Node.js and Express.js with a MongoDB database for scalable data management. Implemented secure authentication using JWT/OAuth, RESTful APIs for dynamic data handling, and modern UI styling with responsive layouts across all devices. Focused on performance optimization, clean modular architecture, error handling, and deployment best practices to deliver a fast, secure, and user-centric web experience.
