We migrate stores off PrestaShop, Magento and Shopify to a modern headless stack — Sylius/Symfony + Next.js. Faster, more stable, easier to scale. No overnight rewrite, no lost traffic.
Technologies and platforms we work with every day
A store that loads slowly loses customers before they even see the product. And on monolithic platforms, every optimization hits the limits of the architecture.
Every extra second of load time lowers conversion. On mobile, the gap between 1s and 4s means real, missed sales.
Google uses Core Web Vitals as a ranking signal. A slow store loses positions — and free organic traffic.
Tens or hundreds of thousands of products bring PrestaShop/Magento monoliths to their knees: slow filtering, sluggish admin, rising server costs.
On classic architectures, every big campaign is a risk. Headless separates frontend from backend and scales them independently.
From full migration to maintenance and hosting — everything performance-related in one place.
We move your store off PrestaShop, Magento or Shopify onto Sylius/Symfony + Next.js, preserving SEO, URLs and order history.
We build Next.js frontends on top of a solid Sylius/Symfony backend: fast, scalable and easy to extend, with an admin experience your team owns.
Auditing and optimization to green CWV: LCP, INP, CLS. We focus on real mobile speed, not just lab scores.
We connect your store to the whole ecosystem: couriers, invoicing, ERP and marketplace feeds — automated and reliable.
A dedicated team that continuously monitors, updates and optimizes. You handle sales, we handle the infrastructure.
Dedicated infrastructure on Hetzner servers, configured and managed by us: fast, secure and free of cloud bill surprises.
A clear process, no surprises. You always know where we are and what comes next.
We analyze your current store, catalog, traffic and pain points. We set measurable performance goals.
We propose the headless architecture, the data migration plan and the SEO strategy to keep your rankings. Clear estimate and timeline.
We build the Sylius/Symfony backend and the Next.js frontend, with incremental deliveries and a staging environment for testing.
We migrate products, categories, customers and orders, with validation and integrity checks. We map every old URL.
Controlled cutover with 301 redirects and real-time monitoring. Goal: zero downtime and zero traffic loss.
After launch we stay on board: monitoring, continuous optimization and new feature development.

No, if the migration is done right. We map all old URLs 1:1, set up 301 redirects and preserve the content structure. The stated goal is zero loss of organic traffic.
