Performance Engineering

Fast is an architecture decision, not a plugin.

Overview

We profile the whole request path (browser, JavaScript, images, CDN, origin server, database), find where the milliseconds go, and remove them. Core Web Vitals improve because the causes are gone.

What we do

Capabilities

Frontend

  • LCP, INP and CLS
  • JavaScript reduction
  • Frontend profiling
  • Font and render strategy
  • Third-party script control

Assets

  • Image pipelines
  • Modern formats and sizing
  • Asset optimization
  • Critical resource loading
  • Video delivery

Edge

  • Caching architecture
  • CDN configuration
  • Cloudflare tuning
  • Cache keys and purging
  • Edge rendering

Origin

  • Nginx tuning
  • OpenLiteSpeed tuning
  • PHP and Node runtime tuning
  • Database performance
  • Query and index fixes

How we approach it

Principles we hold ourselves to

  1. 01

    Profile, don’t guess

    Traces, waterfalls, field data and flame charts first. Nothing gets changed until we know where the time goes.

  2. 02

    Delete before you optimize

    The fastest JavaScript is the JavaScript that never ships. Removing work beats making work faster.

  3. 03

    Cache on purpose

    Explicit cache keys, lifetimes and invalidation. A CDN in front of an uncacheable site is an expensive proxy.

  4. 04

    Keep it fast

    Performance budgets in CI and field monitoring after launch, so the site is still fast ten features later.

Signals

You might need this if…

  • PageSpeed is red and the fixes haven’t stuck
  • Your server struggles under ordinary traffic
  • Interactions lag on mid-range phones
  • There’s a cache, but nobody trusts it

Works with

  • Chrome DevTools
  • WebPageTest
  • CrUX
  • Cloudflare
  • Nginx
  • OpenLiteSpeed
  • Redis
  • PostgreSQL / MySQL

Questions

Asked often

Yes. Plenty of slow sites are WordPress on an under-tuned server. We work on the stack you have and only recommend changing it when that’s the actual fix.

It can be, but audits without implementation rarely change anything. We prefer to do the work and leave monitoring in place.

Changes are staged, measured and reversible. Speed that costs correctness isn’t finished.
