Direct, no agency layer

Looking for a PrestaShop agency? Hire the expert who runs twenty-three storefronts instead.

Most PrestaShop agencies have built a few shops. For an estate of 23 country storefronts across 23 markets I took over from a full tech team and now handle all of it: frontend, backend, module work, security, AWS operations, updates and, right now, the migration to PrestaShop 9 and Hummingbird. That is what a PrestaShop expert or consultant should bring to your store - and here it is the same person from the first call to the deploy.

What a PrestaShop expert actually does for you

PrestaShop is a strong platform with a weak default. Out of the box it ships duplicate URLs, filter navigation that can generate thousands of crawlable URLs, a theme layer that most agencies patch instead of understand, and a module marketplace where quality ranges from excellent to dangerous. The stores that run well are the ones where someone owns the whole stack.

That is the job I do. Custom modules and hooks rather than a plugin for every wish. Theme work in Classic and Hummingbird that survives the next core update. Multistore and multilanguage setups that keep 23 markets on one codebase without 23 forks. And the unglamorous half - PHP version moves, security patches, backups, monitoring - that decides whether a store is still there next year.

  • Custom module development and hook work, with upgrade paths that do not break on the next release
  • Theme development on Classic and Hummingbird, Bootstrap 5 and TypeScript, without jQuery debt
  • Multistore and multilanguage architecture: one estate, many markets, one deploy
  • Integrations with ERP, PIM, payment and logistics providers, built against the Webservice and the new Admin API
  • Performance: caching, database work, image pipelines and Core Web Vitals on real product pages

The proof: one PrestaShop estate, in figures already published

Every claim on this page is backed by one engagement that is documented on this site and corroborated by a third party. Jungheinrich, the material-handling manufacturer, handed me a multi-country PrestaShop estate in 2023 after a full external tech team, with almost no documentation of a heavily customised setup. The case study is on this site; the numbers below are the ones it states.

  • 23 country storefronts in 23 markets, run on one codebase since the 2023 takeover
  • Store revenue doubled since 2023 - at least +20% every year
  • Near-zero downtime, security hardened, stability improved - the three things a takeover has to deliver first
  • Upgrade to PrestaShop 9 and the Hummingbird theme in flight across the estate, legacy modules migrated along the way
  • Independently attested: Cale Edwards (Prediki) describes the takeover, the lack of documentation, the security and stability work and the sales growth in a public LinkedIn recommendation

PrestaShop agency or PrestaShop expert: what you are actually buying

An agency sells you a project manager, a designer, a developer and a support desk, and each handoff between them is where context dies. Jungheinrich handed me storefronts that had been run that way, with almost no documentation, and the estate is healthier now with one person than it was with a team - revenue included.

Working directly means the person who diagnoses the problem is the one who fixes it and the one who is still there when the next release lands. There is no ticket queue between you and the code, and no junior learning PrestaShop on your invoice. When a project needs more hands than mine, I bring in people I have already delivered with - and you still deal with one person who answers for the result.

It also means I say no. If your store needs a fifty-person build with a design studio attached, I will tell you that on the first call and point you somewhere sensible.

Hiring a PrestaShop expert, consultant or agency: what to ask

People search for this under several names - PrestaShop agency, PrestaShop expert, PrestaShop consultant, PrestaShop developer, PrestaShop freelancer - and mostly mean the same thing: someone who has run a real store through real problems and can be reached when the next one lands. Here is how to tell whether you have found one.

  • Ask which versions they run in production today, not which they have read about. The honest answer in 2026 names 1.7, 8 and 9, and has an opinion on Hummingbird.
  • Ask for the module list of a store they maintain and why each module is there. An expert can defend every entry; an installer cannot.
  • Ask how a change reaches the live shop. The answer should include staging, version control and a rollback, in that order.
  • Ask what happens to the URLs in an upgrade. If rankings are not mentioned before you mention them, keep looking.
  • Ask who you will talk to in six months. With one expert the answer is the same person; with an agency it is whoever is on the account by then.

How an engagement runs

It starts with a look at your actual store: the codebase, the module list, the server, the Search Console data. Not a questionnaire. Within that first look I can usually tell you which of your problems are configuration, which are modules and which are structural, and what order to fix them in.

Then the work happens on a staging copy of your shop, deployed through version control, with a rollback path for every change. You see each step before it reaches customers. Nothing is billed as a black box and nothing is locked into me: the code is yours, documented, in your repository.

  • First contact: you send the store URL and what is wrong; you get a reply within two working days
  • First look: codebase, modules, server, Search Console - a written list of findings, ordered by what costs you most
  • Work: on staging, in version control, each change with a rollback path, deployed when you have seen it
  • Handover or standing care: documentation in your repository, and either a clean exit or an ongoing arrangement

Three ways to work together

Scope, timing and cost depend on the store in front of me, so there is no rate card on this site. The shape of the work, though, is almost always one of three.

  • Audit with a defined scope: a full read of code, modules, server, SEO and security, delivered as a written, prioritised list you can act on with me or with anyone else
  • Project: an upgrade to 8 or 9, a Classic-to-Hummingbird theme migration, a custom module, an integration - scoped up front, built on staging, delivered through version control
  • Ongoing care: a standing monthly arrangement that keeps a live store patched, fast, monitored and backed up, with one developer who knows it on the other end of the message

The rest of the cluster

Development is one of four things a PrestaShop store needs from an expert. The others have their own pages, because the questions people ask about them are different.

  • Upgrades and migration: 1.6 and 1.7 to 8, 8 to 9, Classic to Hummingbird, with orders, customers and URLs kept intact
  • Maintenance and support: the standing care that keeps a live store patched, fast and backed up
  • PrestaShop SEO: duplicate content, URLs, filter URLs, structured data and multilanguage hreflang, fixed in the code rather than described in a report

When the project is bigger

I lead every engagement. When the scope needs more than one pair of hands, I bring in people I have already delivered projects with, and you still deal with one person who is accountable for the result. It is not hiring a developer. It is hiring a delivery. Most work stays with me alone; the team is for the projects that need it.

Questions people ask first

Are you a PrestaShop agency?
No - one expert, working directly. What an agency gives you in headcount I give you in continuity: the person who audits your store is the one who changes the code and the one who is still there a year later. For scope that needs more hands I bring in people I have already delivered with, and you keep one accountable contact.
What does a PrestaShop audit look like?
A read of the actual store: codebase and overrides, module list, server and PHP setup, Search Console and access logs, security posture. You get a written list of findings ordered by business impact, each with the fix and its risk. It is designed so you can act on it with me or without me.
Which PrestaShop versions do you work on?
All of them that are still running in production: 1.6, 1.7, 8 and 9. The estate I run is mid-migration from 1.7 to 9, so the differences between them are current knowledge, not something I would need to look up.
Can you take over a store another agency or developer built?
Yes, and that is the normal case. Jungheinrich came to me as customised storefronts with almost no documentation after a full external team. The first step is always an audit of what is actually there.
Do you work with agencies or only with store owners?
Both. Two SEO agencies already use me white-label on Shopify, and the same arrangement works for PrestaShop: your client never needs to know I exist.
How does a PrestaShop 9 or Hummingbird upgrade run?
On a staging copy first, with the URL map and the module inventory written before anything is upgraded, and a rollback path at every step. I am doing exactly this across a 23-storefront estate right now; the upgrade page in this cluster describes the process in detail.
What does it cost?
It depends on the store, which is why there is no price list on this site. Send me the URL and what you need, and you get a straight answer.
Where are you based and which markets do you serve?
Belgrade, working in English, German and Serbian for clients mainly in Austria, Germany and the wider EU. The 22-market estate I run covers most of Europe, so localisation is daily work.
