Hire Replo Landing Page Builder Experts

Speed & Performance Specialist for Shopify Stores - and the measurement behind your revenue

I helped an apparel brand cut product-page load time from 15.4 seconds to 7.4 seconds - five weeks before Black Friday. That's what I do: I find what's slowing your store down and fix it.

The same work keeps surfacing a second problem: stores where the numbers are broken. Pixels firing twice and double-counting conversions. Ad campaigns spending across the whole catalog with no filter on what actually earns. Apps billing every month for work nobody has measured. So alongside speed, I measure what your money - ad spend, apps, tracking - is actually doing, instead of trusting what the platforms and vendors report. Then I fix what the measurement finds.

I specialize in Shopify speed optimization, Core Web Vitals, ad-spend and tracking measurement, and sales-channel recovery for established, founder-run stores. I treat speed and ad spend the same way: as revenue problems, not technical checkboxes.

What I work on:

• Speed audits and Core Web Vitals optimization

• Ad-spend clarity - which products earn your Google/Meta budget, measured per product

• Meta Pixel and GA4 tracking setup, audits, and double-counting fixes

• App and tool bill audits - is each paid app earning what it charges? Where a paid app is doing what Shopify Flow already does natively, I replace it with a built-in workflow, including the multi-step logic that prompt-built automations get wrong

• Sales-channel recovery - when your products stop showing in Google Shopping or on Meta, finding why the catalog fell out (feed disapprovals, a dropped channel connection, market or policy misconfiguration) and getting them back in front of shoppers - verified on the storefront a shopper sees, not a green light in a dashboard

• Server-side tracking and attribution contamination fixes

• Ongoing monitoring and technical support - monthly Store Care across speed, tracking, apps and channels, or a support pack of hours

Key results:

• Product-page load time cut from 15.4s to 7.4s - 52% faster

• Mobile PageSpeed on product pages from 18 to 28 - with the client's chosen app stack kept in place, at their call

• Two apps billing to track what the store's own Google channel already handled - removed, tracking verified clean, and $199/yr off the app bill

• Repeat clients going back to 2018 - one store at 14 projects across four years

How I work:

• A diagnostic audit measures the actual problem - no guesswork, and the audit fee credits toward the fixes

• Phased implementation - you approve each milestone

• Every delivery closes with verified before/after numbers and a short list of the next opportunities I found

80+ projects completed. Clients across the US, Canada, UK, Australia, and Denmark.

Send me your store URL and I'll tell you exactly what's slowing it down - and whether your numbers can be trusted. No commitment needed.

I'm a Shopify developer with years of hands-on experience building and scaling e-commerce stores — from custom theme development to conversion rate optimization and third-party integrations. I've worked with brands like Après Nail and through platforms like Storetasker, delivering solutions that look great and perform even better.

I specialize in Liquid programming, frontend development, and UI/UX enhancement. Whether you need a full theme build, a tricky app integration, or a speed and SEO overhaul, I bring a detail-oriented approach that gets results — not just code.

I leverage AI tools like ChatGPT and GitHub Copilot throughout my workflow — drafting Liquid logic faster, QA-testing edge cases, and generating content-ready section structures. This means faster turnaround, fewer revisions, and more value for your budget.

My background spans custom store builds, GA4 + GTM tracking setups, Klaviyo integrations, loyalty app configurations, A/B testing, and cross-functional collaboration with design and marketing teams. I treat every project like it's my own store on the line.
