Speed, code quality, SEO, and technical performance for Shopify stores that are ready to grow. From a single expert call to ongoing partnership.

Your Shopify store launched fine. Solid theme, a few apps, focused on selling. It worked.
Then things piled up. A reviews app. A loyalty program. Tracking pixels from three ad platforms. Custom code from a freelancer you lost contact with. Shopify makes it easy to add things. That’s its strength. But every app, every snippet, every “quick fix” adds weight.
And when non-technical people make changes, things break in ways nobody notices. Not today. Not next month. But they compound.
Two years later, your website loads in 6 seconds on mobile. Your theme is two major versions behind. Deleted apps still have scripts running. You don’t know what half the code does, but you’re afraid to touch it because last time something broke for three days.
You’re losing traffic because Google ranks slow stores lower. You’re losing conversions because visitors leave before the page loads. You’re burning ad spend sending paid traffic to a site that can’t convert it. None of this shows up on an invoice. It just silently drains revenue, month after month.
And the worst part: you know something is off, but fixing it means spending hours on things you don’t enjoy, don’t fully understand, and that pull you away from what actually grows your brand. Products, marketing, customers, your team.
Website performance isn’t the most important thing in ecommerce. Product, brand, and marketing come first. But if those are working and your site isn’t optimized, everything else is leaking through a broken floor.
Clean code isn’t your job. But someone has to do it.

Hi, I’m Jérémie.
I ran my own Shopify store for 7 years. Not a huge brand, but a decent one. About $4M in revenue over the period, with some months crossing $100k.
I handled the technical side of my store for years. The SEO, the theme work, the app cleanup, the performance fixes. Now I do it for other founders who are where I was.
“Our store was loading in 6+ seconds on mobile. After the Sprint, we're under 2. The difference in conversion rate was visible within the first week.”
“Quick, clear, no BS. Exactly what I needed.”
“Best money we've spent this year. Period.”
“Finally someone who actually explains what's wrong instead of just sending an invoice. The audit report alone was worth it.”
“I was skeptical about paying for a single call, but the 30 minutes saved me weeks of going in circles with my theme developer. Jérémie spotted the issue immediately and walked me through the fix step by step.”
“We went from a 34 to a 91 on PageSpeed mobile. Our ad costs dropped because landing pages actually load now. The ROI paid for the Sprint in the first month.”
“We had three agencies look at our store before. None of them caught the orphaned scripts from apps we uninstalled two years ago. CleanShopLab found them in the first hour and our Lighthouse score jumped 20 points overnight.”
“The ongoing partnership is a game changer. Knowing someone is looking at our store every week means I can focus on product and marketing instead of worrying about what's broken under the hood.”
