ஒரு சிஸ்டம் ডিজைன் சমস்যার কাছে আপনি কীভাবে পদ্ধতিগতভাবে যোগাযোগ করেন?

1. CLARIFY REQUIREMENTS → functional (what it does) + non-functional (scale, latency,
   availability, consistency); scope it (don't assume — ask questions, narrow the problem)
2. ESTIMATE SCALE → users, requests/sec, data volume, read/write ratio → informs the design
3. HIGH-LEVEL DESIGN → main components and data flow (clients, services, databases, caches,
   load balancers, queues); draw the architecture
4. DETAILED DESIGN → data model/schema; key components in depth; APIs; specific challenges
5. SCALE & OPTIMIZE → identify bottlenecks; apply techniques (caching, load balancing,
   sharding, replication, async); discuss TRADE-OFFS
6. ADDRESS concerns → reliability, consistency, edge cases, failures
