Performance & reliability engineering
Core Web Vitals, p99 latency, cache hit rates — green and steady.
Performance & reliability engineering is core web vitals, p99 latency, cache hit rates — green and steady.
Why this work matters
Performance regressions sneak in PR by PR. By month six the page is 4× slower than launch and nobody noticed because nobody was watching. We watch, and we keep budgets.
The work, in detail.
- Core Web Vitals tuning (LCP/INP/CLS)
- Database query optimization
- Cache layering (HTTP, edge, app, DB)
- Edge offload for static + dynamic
- Capacity planning + load testing
- Quarterly perf budgets
- →Perf budget + CI gates
- →Quarterly performance audit
- →Optimized critical paths
- →Capacity & load test reports
We turn dashboards green and keep them green. Real performance engineering, not 'add a CDN'.
The approach.
Perf budgets in CI
Every PR runs Lighthouse + Web Vitals checks against a budget. Regressions fail CI before they merge.
Profile, don't guess
Real flamegraphs, real query plans, real cache hit ratios. Optimization decisions are data-driven; we don't 'add a Redis' on a hunch.
Capacity, ahead of need
Load tests against forecast traffic, not yesterday's traffic. We catch the bottleneck on the next-tier scale, not in the middle of a launch.

Every 90 days you delay is 90 days of authority compounding for someone else. Get the audit. See the math. Then decide.
