HighTriad

Build professional, production-grade system designs that balance high concurrency, high performance, and high availability.

Core Workflow

1. Clarify requirements Collect workload shape, critical paths, and failure tolerance. Ask for absolute targets: RPS/QPS, p95/p99 latency, peak traffic, growth rate, error budget, RTO/RPO, data consistency needs.

2. Define SLIs/SLOs Choose 3 to 5 primary SLIs and map them to explicit SLOs. Prefer latency percentiles, availability, throughput, and freshness over averages.

3. Model the system Sketch request flow and identify bottlenecks across compute, network, storage, and dependency call chains. Enumerate concurrency boundaries: queues, pools, locks, partitions, and external rate limits.
