Make it 10x faster.
Deep Core Web Vitals engineering for sites and apps that need to feel instant, rank higher, and convert more.
Before us. After us.
Actual measurements from a recent optimization on a live production e-commerce site.
Speed is a growth channel.
Performance isn't a technical concern, it's a revenue lever. Here's what changes when your site gets fast.
Core Web Vitals are a Google ranking factor. Faster sites climb organic results, period.
Better UX signals feed back into search and reduce bounce, compounding over months.
Every 100ms shaved off LCP compounds into more paying customers, real revenue impact.
Where we look, what we fix.
Every performance engagement walks this checklist. Not every site needs every fix, but nothing is skipped by accident.
- Route-level code splitting
- Lazy-load below-the-fold
- Remove duplicate deps

The three metrics Google actually ranks on.
How fast the biggest thing on screen shows up. Perception of speed.
How snappy the page feels when you click, tap, or type.
How much the page jumps around as it loads. Zero is heaven.
How we get from kickoff to launch.
Deep audit
Lighthouse, WebPageTest, real-user monitoring, and code review to find the real bottlenecks.
Prioritized plan
Findings ranked by impact-per-hour. You approve the plan before we touch code.
Ship the fixes
PR by PR, with before/after numbers on each. No 'refactor everything' theater.
Zero-regression release
Canary rollout with real-user monitoring so we catch regressions before you do.
Monitor + guard
CI-integrated Lighthouse checks so every future PR keeps the numbers green.
