01
Real device, real network
We test on a mid-tier Android over 4G, not a 1000Mbps fiber connection on an M3 Max. The numbers we report are the numbers your customers experience.
Speed & reliability
Faster stores. Real numbers.
Performance work is the highest-ROI engineering you can do on Shopify — every 100ms of LCP correlates with conversion lift, and Google has been weighting Core Web Vitals into rankings for years. We do the unglamorous deep work: render-blocking JS audit, third-party tag triage, image pipeline, Liquid query optimization, app de-duplication. We benchmark on real hardware and ship until the numbers move.
Outcomes

- LCP under 2.0s on mobile 4G for product detail and collection pages
- INP under 200ms across the funnel
- CLS effectively zero
- Quantified mobile conversion lift
- Quarterly performance budget enforced in CI

Methodology
How we approach the work.
Not principles for principles' sake — these are the practices that decide whether we ship something good or something we'd be embarrassed by.
02
RUM before we touch synth
Real-user monitoring shows where users actually hurt. We prioritize by impact — the slowest 25% of sessions usually drive the biggest wins.
03
Tag debt is technical debt
Most slow Shopify stores aren't slow because of theme code. They're slow because of 14 marketing tags fighting for the main thread. We audit, prioritize, and lazy-load aggressively.
04
Liquid query budget
Hidden N+1 queries in Liquid kill TTFB. We profile every template, eliminate redundant lookups, and cache where the platform lets us.
05
Budget enforced in CI
After we ship, performance only stays good if it's protected. We add Lighthouse CI checks to your pipeline so a regression breaks the build, not the holiday.
