Questions About Hiring a Senior Backend Scaling & Concurrency Architect
How do you diagnose scaling bottlenecks before an outage?
We run k6 distributed load tests combined with Datadog APM distributed tracing to identify exact SQL lock contentions and CPU bottlenecks.
What is the most common cause of backend API crashes under load?
Database connection pool exhaustion caused by serverless functions or container instances opening un-pooled connections directly to the database.
