Arjen Karel's Linkedin Analytics

Most large websites are slow because their architecture is flawed. I show companies how to fix the root cause. My name is Arjen Karel. I don't use guesswork; I use my own RUM platform, @Core/Dash, to get a precise, data-driven diagnosis of where your platform is failing its users. Then, I architect the solution. This isn't about minor tweaks. It's about applying a level of architectural expertise your team doesn't have. THE STANDARD For a large-scale platform, Core Vitals aren't goals. They are architectural requirements. • LCP: Content must render instantly. My architecture ensures it does. • INP: The UI must be immediately responsive. My solutions eliminate input lag. • CLS: The layout must be absolutely stable. I direct the engineering to enforce it. Anything less is an architectural failure. THE RESULT The business result is obvious. A technically superior site ranks higher, converts better, and generates more revenue. This isn't a debate; it's a fact. My work delivers the architectural roadmap to achieve that. ENGAGING WITH ME I solve expensive problems for serious businesses. If that's you, get in touch. If not, don't.
