• Studied the architecture of the railway’s telecommunications network used for mission-critical communication between stations, control centers, and operational units.

• Analyzed the internal IP network infrastructure of the railway system, including routing, switching, and TCP/IP based communication across geographically distributed nodes.

• Observed the deployment and maintenance of fiber-optic backbone networks used for high-speed voice and data transmission across railway divisions.

• Gained exposure to network hardware such as routers, switches, and telecom equipment used to support large-scale distributed communication systems.

• Learned how network monitoring, redundancy mechanisms, and failover strategies are implemented to ensure high availability and reliability of critical communication services.

• Built an e-commerce web application using the MERN stack with features such as product listing, cart, and user authentication.
• Developed REST APIs using Node.js and Express.js for handling user requests and database operations.
• Implemented a ChatGPT-style web interface using React and integrated backend APIs for dynamic responses.
• Used MongoDB for data storage and Git/GitHub for version control during development.
