About this gig
Slow store, lost sales?
Your Shopify store looks good but feels slow on mobile. Every extra second on a product page costs orders, and most speed gigs only chase a PageSpeed number.
Why me
Shopify developer, 16+ years in frontend, Fiverr Pro, 500+ five-star reviews. I build themes myself, so I fix the cause in your theme code instead of hiding it with another app.
What I analyze
Images and hero banners, fonts, theme sections, installed apps, leftover code from removed apps, third-party scripts, layout shifts and Google's real-user Core Web Vitals (LCP, INP, CLS).
What I fix
The highest-impact issues, within your package scope. Every change is made on a duplicate theme, tested on mobile and desktop, and published only with your OK.
What you get
Before and after measurements, a short report of every change, and a prioritized list of what's left (e.g. apps worth replacing).
Not included
Redesign, new features, custom app development, hosting (Shopify handles that).

FAQ
How is this different from cheap speed gigs?
Many speed gigs install an app or delay scripts to push the PageSpeed score. That can break tracking, reviews or the cart. I find the actual cause in your theme and apps, fix it in code and test that everything still works.
Do you guarantee a PageSpeed score of 90+?
No. The PageSpeed score changes on every test and depends on apps you need to keep. I guarantee a measured before and after on the same pages and a clear report of what changed and why.
Which package should I choose?
Basic if one page feels slow and you want quick wins. Standard for most stores: home, collection, product and cart. Premium for stores with many apps, custom sections or ad traffic on several landing pages.
What counts as a page type?
A template your store uses many times, e.g. the product page counts once, no matter how many products you have. Home, collection, product, cart, blog article and landing pages are each one page type.
What access do you need?
Collaborator access with themes and apps permissions. I work on a duplicate of your live theme, so your store stays untouched until you approve the changes.
Will you remove my apps?
No app is removed without your OK. I show which apps slow the store down, what they cost in load time and which ones could be replaced with lighter theme code. Removal of leftover code is included in Standard and Premium.
Does this work with my theme?
Yes, with Shopify OS 2.0 themes like Dawn, Horizon, Impulse, Prestige, Impact, Focal or Empire and custom themes. Very old vintage themes may need a theme update first, I'll tell you before ordering.
Will my tracking still work afterwards?
Yes. I don't block or delay scripts blindly. In Premium I verify that Meta, GA4 and Google Ads still fire after the changes. If tracking is already broken, that's a separate job.
My store is new and has little traffic. Does this help?
Yes. Without enough visitors Google shows no real-user data yet, so I measure with lab tests under consistent conditions. A fast store before launch avoids fixing it later.
What counts as one fix?
One fix is one cause solved on one page type, e.g. the hero image loading too late, an unused app script removed or a font loaded more efficiently. Small related changes count as one.
