OLIVIER ROMERO, SHOPIFY FREELANCE DEVELOPER
I'm Olivier Romero, a freelance Shopify developer and CEO of Agence Shop. I design, redesign, and optimize Shopify stores for French and American brands looking to take their businesses to the next level.
We all know that in 2026, a beautiful website isn't enough. You need to stand out from your competitors, both in terms of the customer journey and the shopping experience, as well as your brand image. And to achieve this, we must succeed in conveying the value of your products as directly as possible and create the desire to buy by activating the right levers.
Finally, a Shopify store evolves in a complex ecosystem: as a Shopify developer, I bridge the gap with the Ads side (Google, Meta, Tiktok, etc…) and SEO.

SHOPIFY DEVELOPMENT. E-COMMERCE STRATEGY. UX DESIGN.
MY EXPERTISE AS A FREELANCE SHOPIFY DEVELOPER
What sets me apart from other Shopify developers is my triple skill set:
- Shopify development : development of Shopify themes, creation of mini-applications to integrate into the theme, performance improvement, integration with other tools (logistics, ERP, email marketing…), technical SEO optimization.
- E-commerce strategy : conversion rate optimization (CRO), average order value, and purchase frequency. These are the three most important KPIs for increasing your revenue – aside from traffic, which depends on your acquisition strategy.
- UX design and branding: creating an optimized browsing experience at all levels, both on mobile and desktop, and aligning the store design with the brand image.
THE SHOPIFY BRANDS I WORK WITH
For several years, I had the opportunity to work in various e-commerce, communication, and digital marketing agencies. This allowed me to implement strategies for diverse client types, from large publicly traded companies and luxury brands to DNVBs (Digitally Native Vertical Brands) and independent e-tailers. This experience enables me to truly understand your needs and not limit my intervention to the technical aspects alone: if you want results, we must consider your environment, your products, your positioning, your brand image, your competitors, your profit margin, and so on.
The Shopify brands I work with are not all alike, but they all have one thing in common: they have a high growth objective, whether it's Bell's Cookies, an American brand that sells more than 500,000 cookies a month, Antésite, an iconic French brand founded in 1898, or niche perfume houses like Les Eaux Primordiales and Brume Orpin.

THE PROCESSES I APPLY TO SHOPIFY PROJECTS
A RESULTS-ORIENTED PROCESS
+101% increase in sales following the redesign of Bell's Cookies' Shopify store
1) Full CRO audit of the Shopify store
2) Plan of concrete and actionable optimizations
3) Creation of UX designs
4) Shopify store development
5) Testing and online deployment
Behind every project, there is a method. My goal is to be the freelance Shopify developer who combines the high standards of an agency with the flexibility, close collaboration, and responsiveness of an independent contractor.
I operate with complete transparency regarding what I implement, why I do it, what recommendations I make, what costs are involved (development, apps, any additional services), and my rates. If several options exist, I explain the advantages, limitations, and short- and long-term impact so that the client can make an informed decision.
Communication is direct, fluid, and ultra-responsive. The client interacts with the person performing the work, not with a series of intermediaries. This allows for quick resolution of roadblocks, adjustment of priorities if necessary, and ensures everyone remains aligned.
Regarding the project, we define clear stages from the outset (audit, scoping, development, testing, deployment, post-launch), and then we proceed as we go. We see things taking shape, and the client can test progressively, rather than waiting for a final "big reveal" with a lot of corrections to make.
The quality of the deliverables: clean and maintainable code, structured theme, impeccable UX, mobile-first experience, stable integrations.
Respect for schedules: we set a realistic framework at the start and I deliver on time.
Finally, there's one criterion that, for me, sums up all the others: customer satisfaction as the sole priority. 100% of customers left a 5/5 rating, which can be verified on Malt and Sortlist.
100% SHOPIFY SUPPORT
Since going freelance, I've become convinced of one thing: to truly excel at something, you need to specialize and not spread yourself too thin. That's why, after several years as a director at a large Shopify agency, I decided to further develop my skills with this CMS, but on my own.
I know the CMS inside and out: the logic of Online Store 2.0 themes, the Liquid language, the structure of templates, the platform's native limitations and the best workarounds when you need to go further, the integration of tracking pixels, but also the configuration of metadata, feeds, sales channels...
I also have a deep understanding of the app ecosystem surrounding Shopify and always recommend the most cost-effective yet efficient options. Examples include customer review solutions, subscription services, upsells, bundles, AI-powered FAQs, and loyalty programs. Furthermore, I always strive to minimize the impact of apps on your Shopify store's performance and, whenever possible, advocate developing custom mini-apps so you don't end up paying for something unnecessary in the long run.
Finally, I keep a really continuous eye on Shopify's developments: new features, changes to the checkout, theme updates, new API features, new SEO features related to the platform, best practices from the international community…
WHAT CLIENTS THINK OF MY SUPPORT: 5/5 ON SORTLIST AND MALT.

THE SHOPIFY PROJECTS I'M WORKING ON
Shopify store creation and redesign.
After meticulously studying every facet of the project and defining a solid CRO strategy, I structured the store and proposed a custom UX design (mobile-first, of course), laying a strong technical foundation: developing a unique theme with modular sections, ad hoc integrations, impeccable technical SEO, and optimized performance. The goal: to launch a Shopify store that won't need to be redesigned after six months, because it was conceived from the outset to evolve with the brand and last for years without any issues.
Optimizing existing stores based on a complete UX and CRO audit.
Here, we don't change everything visually overnight: we start by understanding. I delve into analytics, conversion funnels, heatmaps, mobile and desktop behavior, landing pages, abandoned carts, and acquisition sources. I also look at the store from a user's perspective: readability of the offer, clarity of benefits, reassurance elements, page structure, filters, search functionality, information hierarchy, product page structure…
From this audit, I develop a prioritized roadmap: quick wins (things that can make a rapid difference) and more substantial projects (redesigning certain pages, reorganizing navigation, working on the checkout process, etc.). Most importantly, as a freelance Shopify developer, I implement the recommendations in the theme, adjust sections, review templates, clean up or replace certain apps, update tracking, and propose A/B testing scenarios. We then measure the real impact: conversion rate, average order value, cohorts, bounce rate, and traffic.
FAQ for Shopify Freelance Developers
How to find a good freelance Shopify developer in France?
Start by:
- Look for profiles specializing in Shopify (and not a "generalist web integrator")
- Analyze the shops already completed
- Speak for 30 to 45 minutes with 2 or 3 freelancers to compare:
1) Their understanding of your challenges
2) Their way of structuring the project
3) Their business vision (not just technical)
You can find them through recommendations, freelance platforms like Malt, Shopify communities, on LinkedIn… but the important thing is not the channel, it is the quality of the exchange and the understanding of your project.
What questions should I ask a freelance Shopify developer?
For example :
- “Can you show me 2 or 3 Shopify stores that you developed from scratch?”
- “What do you prioritize when looking at improving a store's conversion rate?”
- “How do you organize a Shopify redesign project, step by step?”
- “How do you manage performance on Shopify?”
- “What complex features have you implemented?”
The answers must be concrete, illustrated with examples, and not purely theoretical.
Can a freelance Shopify developer support me in the long term?
Yes, and it's often an excellent solution that will cost you less than going through a Shopify agency.
You can: - Activate it on a large project (creation / redesign) - Then keep it as a technical reference for your new features, conversion optimizations, campaigns (landing pages, special offers, Black Friday…), etc…
Does the freelancer have to be based in France?
Not necessarily, but for a shop targeting France, a freelancer: - Who understands the local context (expectations of French customers, GDPR…) - Who speaks perfect French - Who knows the carriers and payment methods.
Why hire a freelance Shopify developer rather than an agency?
A freelance Shopify developer offers more direct, flexible, and often faster support than an agency. You communicate directly with the person actually doing the work, eliminating intermediaries, delays, and misunderstandings.
A specialized freelancer can also adapt to the pace of your project, offer tailored solutions, and optimize your budget without sacrificing quality. It's an excellent compromise between high-level expertise and operational efficiency.
An agency remains relevant for highly complex projects or those requiring a full team (branding, media, CRM, etc.). But for the majority of Shopify stores, a good freelance developer allows you to go far, fast, and with high standards.
What can I delegate to a freelance Shopify developer?
You can entrust most aspects of your online store to a freelance Shopify developer. This ranges from creating or completely redesigning the site to more targeted optimizations: improving the customer journey, working on product pages, performance, loading times, mobile experience, or even implementing specific features.
A Shopify freelancer can also handle your theme setup, the integration of useful apps (customer reviews, subscriptions, bundles, loyalty programs, etc.), tracking (Google Analytics, advertising pixels), and technical SEO. For more advanced projects, they can connect everything to your logistics, ERP, or marketing tools to ensure seamless integration.
In practice, you can delegate to him both a "big piece" (creation or redesign) and continuous support to develop the shop as you grow.
How much does a freelance Shopify developer cost? (2026 rates)
In 2026, the rates for a freelance Shopify developer will vary primarily depending on their experience level and the complexity of your project. As a general guideline, a junior developer will typically charge between €250 and €400 per day, an intermediate developer between €400 and €600 per day, and a senior or expert developer over €600 to €800 per day.
For creating or redesigning an online store, budgets are generally based on a fixed price. A store with a fairly simple theme configuration often costs between €1,000 and €2,000. A more comprehensive project, with significant work on UX, performance, and basic SEO, is typically between €2,000 and €4,000. For a highly sophisticated store, with a conversion strategy, premium design, complete technical SEO, and advanced integrations, it's not uncommon to see prices between €4,000 and €10,000, excluding very specific projects (complex migrations, ERP integration, complete email strategy, etc.).
The important thing is not just the price but what is included: clear scope, precise deliverables, level of support, follow-up after going live and real impact on your results.
What are the common mistakes when choosing a Shopify developer (and how to avoid them)?
A common mistake is choosing a service provider who "does everything" but isn't truly a Shopify specialist. This might work for a very simple website, but as soon as performance, conversion, or integration issues become critical, the limitations quickly become apparent. It's better to select someone who works with Shopify daily and is well-versed in its strengths and weaknesses.
A second mistake is choosing solely based on price, without considering quality, existing online portfolio, and working methods. A very low price might indicate a lack of experience, difficult-to-maintain code, or a website that will need to be rebuilt sooner than expected.
Finally, many brands start without a well-defined scope or clear priorities. As a result, expectations are misaligned, the project goes off track, and everyone gets frustrated. To avoid this, always ask the developer to explain their methodology, detail the project's stages, and specify what will be delivered, tested, and measured.
What is the difference between a Shopify developer, a Shopify expert, and a Shopify integrator?
A Shopify integrator primarily focuses on the layout: they configure a theme, add your content, adjust a few sections, and manage simple modifications without delving too deeply into the code or site architecture. This is sufficient for a small project or a very basic first version.
A Shopify developer goes further. They are proficient in Liquid, JavaScript, the structure of Online Store 2.0 themes, performance optimization, and integrations with other tools. They can create custom sections, optimize code, solve complex technical problems, and adapt the site to your specific needs.
A Shopify expert, finally, combines this technical mastery with a true e-commerce vision: strategy, customer journey, conversion, SEO, app selection, catalog structure, and alignment with your marketing campaigns. They don't just execute tasks; they help you make the right decisions so your Shopify store truly supports your business objectives.
In some cases, the same person may combine the roles of developer and Shopify expert, particularly when it is a very senior and specialized freelancer.
