Hey Product Hunt! 👋 Really excited to share what we've built with System Overflow. The Problem We Saw: Most engineers prep for FAANG system design interviews the same way: memorize solutions to 50 common problems (Design Twitter, Design Uber, etc.). They'd nail the template... then completely freeze when asked "Why Cassandra instead of PostgreSQL here?" The issue? Cramming templates, not understanding fundamentals. What Makes System Overflow Different: 📚 Fundamentals Over Templates - Master core concepts (caching strategies, database sharding, consistency models) that apply to ANY design problem, not just memorized solutions. ⚖️ Trade-offs at the Core - Every concept teaches WHY you'd choose one approach over another, with real failure modes and production insights. ✏️ Practice with AI Feedback - Draw your architecture diagrams, get instant evaluation on what you missed (data model, scalability, edge cases). 📊 33 Topics, 200+ Concepts, 3000+ Cards - From fundamentals (load balancing, message queues) to advanced patterns (CQRS, event sourcing, ML system design). Built for Senior+ Engineers: This isn't LeetCode for system design. We're focused on depth over breadth; the kind of understanding you need for L5/L6+ roles at top companies. Would love your feedback on: - What's missing in your current interview prep? - Topics you'd want us to cover next? - Features that would make this more valuable? Thanks for checking us out! Happy to answer any questions. 🚀
