Your customers abandon slow pages. Google ranks slow sites lower. I find what’s actually slowing your e-commerce store — using real-user data — and fix it. More speed, more conversions, more revenue.
No commitment. No sales call. Just real numbers for your site.
The cost of a slow site
Sources: Google Deloitte / Akamai conversion studies. Speed isn’t a vanity metric — it’s directly tied to how many visitors buy.
I don’t sell generic “make it faster” hand-waving. I use real-user field data, then make specific changes that move your revenue.
Real-user field data from Google’s Chrome UX Report, not synthetic guesswork. I find exactly what makes your store slow for actual visitors.
Concrete code changes — image pipelines, render-blocking JS, third-party scripts, caching, hydration. Vue, Nuxt, Astro, WordPress, Shopify.
Dashboards on your real-user p75 LCP, INP and CLS. Catch regressions before they cost you revenue and rankings.
Three steps. The first one is free.
I pull your site’s real Google CrUX numbers and a Lighthouse pass — no commitment, no sales call. You get a plain-English report of what’s slow and why it matters.
A ranked list of changes by revenue impact, not vanity scores. You see the expected payoff before anyone writes code.
I implement the fixes, deploy, and we watch the real-user numbers move. You keep the dashboards and the gains.
I’m a web engineer based in the Netherlands who specializes in performance. My stack is Vue, Nuxt and TypeScript, and I’ve shipped fast sites on Astro, WordPress and Shopify.
Most agencies run a Lighthouse report and guess. I start from your store’s real Google Chrome UX data — what actual visitors experience — because that’s what affects rankings and conversions.
I work directly with store owners and small teams. No account managers, no bloated retainers. Just someone who cares about your numbers.
Tell me about your store. I’ll pull your real Core Web Vitals numbers and send back a short report — usually within one business day.
