Core Web Vitals consultant for ecomm & agencies | Google Developer Expert | audits, talks & in-house training 🎓
Want to beat your competition on page load time? Seeing too many abandoned carts? Slow sites cost you money: → 1-second delay = 7% fewer conversions → 3 seconds = 40% of visitors gone → Slow loading = Google dropping your rankings I help ecommerce brands and agencies fix these problems without the technical headaches. Whether you need to boost Core Web Vitals, stop layout shifts frustrating your customers, or simply convert more visitors, I've got practical solutions that actually work. Following (or connecting) me here on LinkedIn will be a first step towards increasing pagespeed, browser and debugging knowledge. Need a speed boost or team session today? There's a faster way: As a Google Developer Expert who's helped brands like Danone and Wehkamp, I speak plain English or tech jargon, tailored to your team. I'll work directly with your team to make performance improvements (and revenue) stick via interactive sessions. With the ultimate goal to get fast, stay fast and increase your (customers') SEO and revenue month on month. What started as a developer journey in 2001 (building my own CMS because... why not? 😜) evolved into creating RUMvision—a tool that shows how real people experience your site, not just what Google's lab tests say. I'm also an international speaker, having shared insights on how to improve web performance at conferences like Performance.now(), We Love Speed, MageTitans and others. I'm platform-agnostic: Magento, Shopware, BigCommerce, Hyvä, Shopify, SPA's like React or Vue or custom builds—if it loads in a browser, I can make it faster. Follow me for tips that make web performance less boring, or let's chat about how to stop losing sales to slow load times.
