Hire PrestaShop Developer — Modules, Multishop & Performance Tuning
Most PrestaShop pain comes from core hacks and half-built modules that break on every update. I build with overrides, clean hooks, and native module structure so upgrades from 1.7 to 8.x stay routine instead of terrifying. Multishop setups, tax rule matrices, payment and ERP integrations — done properly, documented, and handed over without vendor lock-in.

What a PrestaShop Developer Actually Delivers
Custom Modules, Built Native
Native modules built with hooks and overrides, never core file edits, so your store survives upgrades. Each ships with an admin panel, multishop support, and clean uninstall logic for payment, carrier, or import workflows.
1.7 to 8.x Upgrades
Upgrades fail on incompatible modules and theme overrides. I audit them first, fix or replace what breaks, then migrate in a staging clone before production. Data, order history, and customer logins carry over intact.
Multishop Architecture
Run multiple storefronts from one back office with shared stock and per-shop pricing. I plan shop groups and URL structure, migrate catalogs into the multishop tree, and verify checkout, taxes, and shipping per shop.
Performance Tuning
PrestaShop slows on bloated modules and unindexed queries. I profile with query logs, trim module overhead on product and checkout pages, configure caching and CDN, and cut page weight so critical pages respond fast.
Payment & ERP Integrations
Stripe, PayPal, Tabby, regional gateways, and ERP or warehouse systems wired through clean service layers. I handle webhook reliability, order status mapping, refund flows, and failure alerts so money movement never silently breaks.
Theme & Checkout Customization
Custom themes and checkout flows built on PrestaShop conventions, not page-builder hacks. I rebuild slow themes, fix mobile checkout friction, and implement one-page checkout, address validation, and trust elements that lift conversion.
How the Engagement Works
A structured engagement with no surprises — you’ll always know what’s happening and what’s next.
Audit First
You share store access and the pain list. I review modules, overrides, theme code, and server setup, then send a written findings report with a fixed-scope quote.
Stage Everything
All work happens on a staging clone of your store first. You click through checkout, payments, and admin flows yourself and sign off before anything touches production.
Deploy & Verify
I deploy during low-traffic hours, run post-deploy smoke tests on checkout and payments, and monitor error logs for 48 hours to catch anything staging missed.
Handover Docs
You get documentation of every change, module settings, and deployment steps, plus a short call walking your team through maintenance so you are never dependent on me.
Why Work With Omer on PrestaShop
PrestaShop rewards developers who respect its architecture and punishes core hackers. With 15+ years across 100+ projects in 6 countries, I have rebuilt stores others abandoned and carried them through version upgrades. You get judgment on what to customize, what to configure, and what to leave alone.
I work as a fractional CTO, which means direct communication, weekly demos, and no handoffs to juniors. Every engagement starts with a conversation — get in touch to discuss your store.
Frequently asked questions
How long does a PrestaShop upgrade take?
A 1.7 to 8.x upgrade typically takes two to four weeks: module audit, staging migration, and testing. Heavily customized or multishop stores take longer, and the upfront audit gives you an exact timeline before work begins.
Can you fix a store another developer broke?
Yes, rescue work is common. I audit for core hacks and broken overrides, stabilize checkout and payments first, then refactor toward upgrade-safe patterns. You get a written report of what was wrong and what changed.
Do you work with PrestaShop multishop?
Yes. I set up shop groups, shared carts and stock, per-shop domains, themes, and pricing, then migrate existing catalogs into the multishop tree. Post-launch I verify checkout, tax rules, and shipping on every storefront.
Will my store go down during the work?
No. Everything is built and tested on a staging clone first, and deployments happen during low-traffic hours with post-deploy smoke tests. Most upgrades and module installs complete with zero downtime for shoppers.
Do you provide ongoing PrestaShop maintenance?
Yes. Monthly retainers cover security patches, module updates, backups, uptime monitoring, and a set number of small improvements. You get a monthly report of everything patched, updated, or fixed.
What Changes the Day You Hire a PrestaShop Developer Who Works With the Framework, Not Against It
When you hire a PrestaShop developer, the first thing I do is measure how far your store has drifted from the framework itself. PrestaShop 8 still runs two worlds side by side: the legacy layer built on ObjectModel and classic controllers, and a modern back office rebuilt on Symfony with a dependency-injection container. Most stores I inherit have been patched in whichever layer was convenient at the time, so I map that honestly before I touch anything. I want to know which features live in real modules, which hide in core edits, and which depend on a marketplace plugin that is one update away from breaking. That map is what separates a quick, safe engagement from an expensive archaeology dig later.
My default approach is to keep every change reversible and upgrade-safe. I reach for hooks and the proper module structure first, service decoration through the container second, and legacy overrides only as a last resort with the override cache respected. Data access goes through ObjectModel and DbQuery with the right indexes, never raw SQL buried in Smarty templates. On the infrastructure side I run Redis for cache and sessions, tune OPcache and the PHP-FPM pools, and profile with Blackfire alongside PrestaShop's own debug profiler and SQL query explorer so decisions rest on real timings rather than guesswork. Theme work happens in a child of the classic theme built with Webpack Encore, with Composer and Git managing dependencies and deploys.
Good, to me, means your store survives the next upgrade without a developer in the room. Every customisation sits in a module or a child theme, so the core migrator and a dependency update run clean instead of throwing fatal errors. Good means a warm-cache time to first byte in the low hundreds of milliseconds, a product page that issues a handful of queries rather than hundreds, and a Lighthouse profile where the largest contentful paint and interaction timings actually pass on mobile. It means a staging clone I can rebuild from one command, so a fix is proven before it ever reaches your customers. If I cannot measure it, I treat it as not yet done.
The mistakes I fix most often are predictable once you have seen a few hundred stores. Direct edits inside the classes and controllers folders that silently break on every upgrade. A specific_price table bloated to hundreds of thousands of rows by a careless cart rule, quietly crippling every product page. Combinations generated into the tens of thousands with no cleanup, a dozen half-overlapping SEO and speed modules from the marketplace fighting each other, Smarty force-compile left switched on in production, and sessions pinned to the filesystem on a load-balanced setup. I unwind those back to native mechanisms, document what changed, and leave you with a store a future developer can actually read.
When clients hire me for this
Stuck on an end-of-life version
Your store still runs PrestaShop 1.6 on PHP 5.6, payment gateways are dropping support, and every quote you have had warns of a risky big-bang rebuild. I audit the real customisations, rebuild them as modules and a child theme on a staging clone, then step the store up through the supported upgrade path to 8.x with the data intact.
Checkout and product pages crawling
Traffic is fine but the store feels heavy, time to first byte spikes under load, and the cart abandons. I profile the real bottleneck, usually a runaway specific_price table, uncached blocks, or a module querying on every page, then fix it at the source and add Redis and proper caching so the storefront stays fast at peak.
A previous developer left a mess
Core files were edited by hand, a key module throws a fatal error, and nobody knows what is safe to change. I stabilise checkout and payments first, reconstruct the lost customisations the right way, remove the conflicting plugins, and hand you a written record of exactly what was changed and why.
Scaling into new markets
You are expanding into new countries and need per-country pricing, currencies, languages, tax rules, and a proper hreflang setup, plus live stock and orders syncing to an ERP. I design the multistore and integration layer so each storefront behaves correctly and the back office stays a single source of truth.
Questions buyers ask
How much does it cost to hire a PrestaShop developer like you?
I work on fixed-scope quotes for defined projects and a monthly rate for ongoing work, not hourly ticket-chasing. After a short paid audit I give you a firm number tied to deliverables, so you are never surprised by the invoice. A focused fix or module usually lands in the low four figures; a full upgrade or multistore build is scoped against the actual customisations the audit uncovers rather than a guess.
Is PrestaShop 8 production-ready, and should I upgrade now?
Yes, 8.x is stable and is where active security and PHP 8.1 and 8.2 support live, so staying on 1.7 or 1.6 is the real risk. The honest catch is the half-finished Symfony migration: some back office pages are modern, others still legacy, and a few older modules need patching for compatibility. When you hire a PrestaShop developer for this, that compatibility check is exactly the work, and I prove every module on staging before going live.
Can you migrate my store from PrestaShop to Shopify, or from Shopify to PrestaShop?
I can, and I will tell you honestly whether you should. PrestaShop wins when you need deep B2B logic, complex tax and multistore rules, or full control without per-transaction platform fees; Shopify wins when you want to outsource hosting, PCI, and maintenance entirely. If a move makes sense I handle the catalogue, customer, order, and URL redirect migration so your SEO and history survive the switch intact.
Can you build a headless PrestaShop setup or connect it to a mobile app?
Yes. PrestaShop 8 ships a REST-style Webservice API, and I extend it with custom module endpoints so a React, Next.js, or native mobile front end can read the catalogue and push orders while PrestaShop stays the commerce and back-office engine. I am candid about the tradeoff: headless adds real maintenance surface, so I only recommend it when your front-end ambitions genuinely outgrow the Smarty theme layer.
Can you fix my PrestaShop SEO and Core Web Vitals, not just the code?
Yes, and the two are usually the same problem. I clean up friendly URL rewrites, canonical tags, duplicate faceted-navigation pages, hreflang across languages and stores, and structured data, then attack the performance side that Google now measures directly. That means deferring and bundling assets through Encore, trimming render-blocking modules, lazy-loading imagery, and caching so largest contentful paint and interaction-to-next-paint pass on real mobile devices.
How do we actually work together, and does your time zone matter?
I run the engagement as a fractional CTO rather than a faceless outsourcer: you deal with me directly, we agree scope up front, and I share working demos on a regular cadence so you see progress, not status reports. I am Dubai-based and already work across the UAE, US, UK, Canada, Pakistan, and Malaysia, so there is a comfortable overlap with most of Europe, the Gulf, and North and South American mornings.
