Performance Engineering for Teams That Ship Fast

Every application has a performance ceiling. You hit it when your P99 starts creeping up, when your database CPU is above 80%, when your Core Web Vitals turn red, or when a customer says “your app feels slow.”

performance.qa exists because most engineering teams don’t have a dedicated performance engineer — and they shouldn’t need one full-time. We provide performance engineering expertise on demand: profiling, bottleneck analysis, and optimization sprints that ship measured improvements in days.

What Makes Us Different

We work across the full stack — frontend rendering, backend services, database queries, and infrastructure configuration — because performance problems don’t respect layer boundaries.

• We measure everything. Every optimization ships with P50, P95, P99 latency before and after. The improvement is a number, not a feeling.
• We work in your codebase. We submit pull requests, follow your code review process, and deploy through your CI/CD pipeline. All code is written to your team’s style guidelines.
• We profile production. Staging performance numbers lie. We use low-overhead profiling tools — continuous profiling, eBPF-based tracing, and sampling approaches — that give production-accurate data with less than 1% overhead.

Our Methodology

1. Measure current performance with production data
2. Profile the request path from browser to database
3. Identify root cause bottlenecks (not symptoms)
4. Implement the fix in your codebase
5. Measure the improvement with production data
6. Document for your team to maintain
