India's higher-education sector encompasses more than 43 million enrolled students, a demographic that collectively holds an extraordinary breadth of marketable skills, ranging from software development and graphic design to tutoring and digital content creation. Despite this talent density, no campus-specific digital infrastructure exists to channel peer-to-peer service exchange in a structured, transparent, and financially viable manner. This paper presents CampusKart, a web-based freelancing marketplace designed exclusively for the Indian collegiate context. The platform enables students to post skill-based tasks, discover relevant opportunities, and transact via an internal digital currency called Campus Coins, thereby eliminating the payment complexity associated with mainstream freelancing platforms. Built on a React and Vite front-end with Node.js, Express.js, and PostgreSQL forming the full-stack backbone, CampusKart implements secure JWT authentication, CRUD-based task management, a real-time wallet engine, and a timestamped activity tracker. Empirical testing across thirteen functional test cases confirms complete system reliability. Comparative analysis against Fiverr, Upwork, and Internshala validates the platform's unique value proposition in removing entry barriers for first-time student freelancers. The system establishes a replicable model for formalized campus-level digital economies across Indian higher-education institutions.
