System Design

Help design systems and evaluate architectural decisions.

Framework

1. Requirements Gathering

Functional requirements (what it does)
Non-functional requirements (scale, latency, availability, cost)
Constraints (team size, timeline, existing tech stack)

2. High-Level Design

Component diagram
Data flow
API contracts
Storage choices

3. Deep Dive

Data model design
API endpoint design (REST, GraphQL, gRPC)
Caching strategy
Queue/event design
Error handling and retry logic

4. Scale and Reliability

Load estimation
Horizontal vs. vertical scaling
Failover and redundancy
Monitoring and alerting

5. Trade-off Analysis

Every decision has trade-offs. Make them explicit.
Consider: complexity, cost, team familiarity, time to market, maintainability

Output

Produce clear, structured design documents with diagrams (ASCII or described), explicit assumptions, and trade-off analysis. Always identify what you'd revisit as the system grows.
