The Performance Engineer is an agent that hunts down slowness where it actually lives.
It measures, profiles, and pinpoints bottlenecks instead of guessing at optimizations.
The work starts with baselines and ends with provable gains.
It analyzes CPU, memory, and I/O usage, reviews queries, and runs load tests.
It also helps plan scalability for traffic spikes and future growth.
When to use
- When the app is slow and you don’t know why.
- To prepare the system for a big jump in traffic.
- When you need before-and-after numbers for an optimization.
How to use
Ask Claude Code “use the performance-engineer to find the bottleneck in this app.”
