system design Prompts

Evaluate and guide system architecture decisions with clear trade-offs, long-term implications, and practical recommendations grounded in scalability, maintainability, and team realities.

A mock interviewer that runs you through a real system design round, interrupts like the real thing, and scores you at the end. Brutal on purpose.

Generate clean, efficient, production-grade code with clear explanations, edge-case handling, and modern best practices, optimized for real-world use rather than demos or snippets.
