Zuvelio · load time after headless rebuild
We rebuild slow, outdated platforms in Next.js — for the speed and UX that actually move your numbers.
Get a free platform auditFit
Running on an outdated stack, a generic template, or something a past developer left half-finished.
Page speed, mobile experience, or admin usability is visibly holding the business back.
An agency or freelancer overpromised, under-delivered, and left you wary of the next pitch.
Strategy
One problem. Any industry.
We've fixed it for a jewelry brand, an exam-prep platform, and a marketing agency. If your platform has this problem, the fix looks the same regardless of what you sell.
Services
Slow load times, buggy features, or a codebase nobody wants to touch. We audit first — Chrome DevTools, Lighthouse, a real read of the code — then give you a plain-English report on what's actually wrong before fixing anything.
Keep Shopify or WordPress running your backend and content. We rebuild the storefront in Next.js so pages load fast and rank better, without you re-entering a single product.
Custom dashboards built around your actual data — role-based access, live charts, exports — not a generic admin template with your logo on it.
A working product, not a landing page with a waitlist form. Auth, billing, and one core feature that actually works, so you can get it in front of real users fast.
All engagements are project-based with clear fixed scope and pricing agreed upfront — no retainers, no surprise invoices.
