Code Master: A Web-Based Competitive Programming Practice Platform

In today’s technology-driven world, competitive programming platforms such as LeetCode, HackerRank, and Codeforces have become essential for improving algorithmic thinking, interview readiness, and coding proficiency. This work presents the design and development of two simplified yet scalable web-based platforms — Coding Practice Website and CodeMaster — both of which replicate the core functionalities of established systems while remaining adaptable for educational and institutional use. The platforms enable secure user registration, categorized problem listings, submission tracking, and real-time leaderboards that evaluate user performance based on efficiency and accuracy. Implemented with a full-stack architecture integrating HTML, CSS, JavaScript/React on the frontend, PHP/Node.js/Flask on the backend, and MySQL for database management, the systems demonstrate effective use of modern web technologies in educational software development. Designed with extensibility in mind, both platforms support advanced features such as integrated code editors, real-time execution using APIs like Judge0, and gamification elements such as badges, levels, and contests. By combining structured practice, performance analytics, and user engagement strategies, these projects highlight the potential of lightweight, scalable platforms to foster computational thinking and enhance coding education in both individual and collaborative settings
