SHOPIFY PERFORMANCE · BY NITHU
Less waiting.
More time shopping.
A slow store gets in the way of a good product. I find and fix the theme code, oversized images and app scripts slowing down your Shopify store—with mobile shoppers at the center of every change.

Performance priorities, not a claim of measured results.
01 / FIND THE FRICTION
A heavy banner, a sluggish product selector or an app loading on every page can each need a different fix. My Shopify performance optimization service starts by finding what is actually slowing your store down.
Review Liquid templates, CSS and JavaScript for unnecessary work. Improve resource loading, investigate render-blocking code and simplify expensive template logic where the audit shows a bottleneck.
A lighter foundation for your store ↗Serve product and banner images at suitable sizes, use responsive images and reserve their space. Prioritize the main visible image; lazy-load media further down the page.
Your products stay sharp. Pages get lighter. ↗Check app embeds, old snippets, tracking scripts and duplicate libraries. Remove unused app code only after checking dependencies, and adjust nonessential scripts without blindly delaying your store’s features.
Keep useful features. Reduce wasted work. ↗02 / MOBILE COMES FIRST
Desktop results don’t tell the whole story. Mobile devices often have less processing power and slower connections, so a store that feels quick on your laptop can still make customers wait on a phone.
I review the mobile shopping journey: the first visible content, navigation, product gallery, variant selector and cart drawer. The goal is to reduce loading delays and keep the actions that matter responsive.
03 / MEASURE WHAT MATTERS
Loading, responsiveness and stability shape how your store feels. I use these metrics to prioritize fixes, alongside practical checks of your storefront.
Investigate the hero or product image, critical styles and resource priority so shoppers can see the main content sooner.
Profile JavaScript and long tasks that delay taps on menus, filters and product options. Reduce work that blocks the browser.
Reserve space for images and app content, and review font loading so text, product details and buttons move less as the page loads.
These are Google’s “good” thresholds, assessed at the 75th percentile of visits—not guaranteed outcomes. Read how Core Web Vitals are measured ↗
Lighthouse tests help diagnose issues in a controlled run. Field data reflects real visitors; PageSpeed Insights uses a rolling 28-day window where sufficient data exists. Improvements won’t appear in that history immediately.
04 / A CLEAR WAY FORWARD
You know what needs attention, what the work includes and how the changes will be checked before anything goes live.
Share your store URL. I review the public storefront and identify likely bottlenecks, affected templates and the next checks needed.
We confirm priorities, package, access and delivery timing. Paid apps, a new theme or work outside the agreed scope are discussed separately.
Theme changes are prepared on a duplicate where practical. App settings that affect the live store are discussed before they are changed.
Retest the agreed URLs, check key shopping actions and review the changes before publishing. You receive a summary of fixes and remaining limitations.
05 / EVIDENCE YOU CAN UNDERSTAND
A number is useful when you can see what was tested. Your optimization report compares the agreed pages using consistent test settings and explains which changes were made.
Results vary with your theme, apps, content and third-party services. I don’t promise a universal 90+ score or a guaranteed ranking increase.

06 / SIMPLE STARTING POINTS
Choose a starting point. The free audit helps confirm which package fits your store.
Prices are in USD. Choose a package to review it at checkout, or request an audit first if you are unsure. Scope and timing are confirmed before work starts.
BASIC
For a small set of straightforward loading issues.
STANDARD
For stores needing theme, image and app-loading improvements.
PREMIUM
For deeper theme issues and custom script investigation.
A one-time optimization engagement for one store and the page coverage listed above. Representative URLs and an implementation checklist are agreed before changes begin. This is not an unlimited-fixes package or a theme rebuild.
Nithu confirms a delivery estimate and the included support window in writing after reviewing the theme, app dependencies and access. Follow-up covers handover questions and the agreed changes; new features, new app conflicts and ongoing monitoring need a separate scope.
Payment records your selected package; implementation starts after the scope is confirmed. If the review identifies larger work, Nithu explains the options before proceeding. Extra work requires your agreement. Cancellation and refunds follow the refund policy.
Theme rebuilds, new functionality, paid app fees, subscription costs and recurring maintenance are excluded unless agreed separately. Shopify checkout or third-party app internals may be outside the changes your theme allows.
Unsure which option fits? Request the free audit before purchasing.
The number of templates, theme customizations, app dependencies and depth of the fixes determine the work involved. A theme rebuild, paid app subscriptions, new features and ongoing maintenance are outside these packages unless separately agreed. Ask for a custom quote if your audit reveals a larger project.
07 / MEET YOUR DEVELOPER
I’m Nithu, the developer behind NithuDev. I combine theme-code investigation with practical storefront testing, so your performance work has one point of contact from the audit to the handover.
You can review my professional profiles and discuss your store before deciding to proceed.

Still unsure what your store needs?
Start with a free Shopify speed audit.
The listed packages are Basic at $49, Standard at $99 and Premium at $149 USD. The right option depends on your theme, apps, affected templates and the fixes required. Your audit helps confirm the scope; larger custom work is quoted separately.
Common causes include oversized images, too much JavaScript, app embeds, heavy sliders and resources that block the first render. Mobile devices and connections can make these issues more noticeable. An audit identifies which factors apply to your store.
Often, yes. Image loading, script timing and unnecessary theme code can be improved within an existing theme. If the theme’s structure is a major limitation, I explain the tradeoffs before recommending a larger change.
Some apps add scripts, widgets or network requests to the storefront. The effect depends on how they load and where they run. I review their performance cost and dependencies before proposing removal or changes, including old code left by previously installed apps.
The initial audit reviews your public store URL for visible performance problems and likely priorities. It helps define the next steps and a suitable package. Code changes and deeper investigation requiring Shopify access belong to the agreed paid scope.
Timing depends on the theme, app dependencies and number of templates involved. I confirm a delivery estimate after reviewing your store and the required access. Real-user reports may take longer to reflect the work because they aggregate historical visits.
Yes. Shopify product page speed optimization can cover product media, variant scripts and app widgets. Collection page work can cover image grids, filters and pagination. We agree the templates and representative URLs before the work begins.
An app can help with a specific task, such as image processing. It may not resolve inefficient custom code or conflicts between other apps. A developer can investigate the cause and make targeted changes. The audit helps determine whether an app, a code fix or a combination makes sense.
No universal score or ranking is guaranteed. Results depend on your storefront, third-party services, test conditions and other search signals. I focus on measurable improvements, functional checks and a clear explanation of remaining constraints.
No password is needed for the initial public-store audit. If we proceed, access is arranged through an appropriate Shopify collaborator invitation. Theme changes are prepared on a copy where practical, with live app-setting changes and publication discussed first. Please do not send passwords through this form.
