I will do shopify speed optimization and boost your core web vitals score
Shalena Opbroek
About this gig
A slow store loses sales before your customer even sees a product. I fix that with measurable results, not vague promises.
I am part of CivSec S.M.A.R.T, a Netherlands-based dev studio with our own app live on the Shopify App Store. We build every product to strict performance budgets, and I apply exactly the same method to your store.
What I do:
- Full speed audit (Lighthouse and Core Web Vitals)
- Image optimization and lazy loading
- Theme and app script cleanup (the usual killers)
- Cache and CDN configuration
- Before and after report with real numbers
Recent real results on client sites, measured with Google PageSpeed: 63 to 83 and 73 to 80 in round one. Our own site scores 95.
Basic is a quick-wins pass delivered within 24 hours. Standard is the full optimization. Premium adds a deeper theme refactor plus 30 days of monitoring.
Send me your store URL before ordering and I will confirm what is achievable for your theme.

FAQ
Can you guarantee a specific score?
I guarantee a measured improvement with a before and after report. Absolute scores depend on your theme and apps. I tell you upfront what is realistic.
Do you need access to my store?
Yes, collaborator or staff access. I explain exactly how to grant it safely after you order.
Will anything break?
No. Every change is tested against the real flow before handover, and I document everything I touched.
