Real-Time Coding Duel Blueprint
Budget: $30 – $250 USD
I’m planning an interactive, data-structures-and-algorithms-focused coding duel platform and I need a crystal-clear design and architecture proposal before any code is written. The end product must feel like a learning arena first and a competition second, so every technical choice has to support quick feedback, fairness and easy-to-follow analytics for students.
Core experience to address
The platform will present the same DSA question to two users simultaneously, lock them into a fixed countdown and stream their code through a real-time execution engine so they can see results (compile errors, test-case pass/fail, runtime, memory) without refreshing. While live chat or leaderboards may appear later, this first proposal must concentrate on that real-time duel loop and the backend scalability it demands.
What I expect from you
• A concise yet thorough architecture document (diagrams, component breakdown, data flow, tech stack rationale).
• A sequence diagram of the duel session, covering question delivery, timer sync, code submission, sandboxed execution, result broadcast and final scoring.
• Recommendations for languages, frameworks, containers, queueing and sandboxing tools that keep latency low and security tight.
• A brief plan for unit, integration and load testing—especially around the execution sandbox.
• Thoughts on how future add-ons (chat, leaderboard) would plug into your design without rewrites.
Send a detailed proposal outlining these points, highlight any similar platforms you’ve designed, and feel free to suggest creative solutions that stay true to the educational goal.
