Hi, I'm Michał. I build e-commerce that holds up under real traffic and scales as the business grows.

E-commerce architect and PrestaShop expert. I design stores, integrations, and custom Laravel systems built to run fast, stay reliable, and hold up under growth, from first launch to scaling for high order volumes.

Architecture Built for Real Business

E-commerce systems built around the actual business, not a ready-made template, that handle high sales volume without breaking under load.

Integrations with ERP, WMS, wholesalers, and logistics, plus data migrations that don't interrupt the store's operation.

I apply the same architecture day to day as CTO at Webixa.

Best Open Source PIM Systems for Ecommerce - an Implementation Comparison

PIM system comparisons online are usually written by the vendors of those systems. This one is different - I write it as someone who implements them for clients and lives with the consequences of bad architectural choices. I evaluate UnoPIM, Akeneo CE, Pimcore, AtroPIM and LibrePIM from the perspective of implementation cost, infrastructure requirements and e-commerce integration realities.

PIM for Allegro and Amazon sellers - how to stop manually copying data between channels

Allegro requires different attributes than Amazon. Amazon requires different images than your store. And Allegro's new algorithm increasingly penalizes incomplete product data. If you are maintaining your catalog manually in several places at once - this article is about what that costs you and what to do about it.

UnoPIM vs Pimcore - which open-source PIM to choose and for whom

Pimcore and UnoPIM are both open-source, both without licensing costs. That is where the similarities end. Pimcore is an enterprise-scale data management platform - PIM, MDM, DAM and CMS in one. UnoPIM is a system designed to do one thing: manage product information for e-commerce. I compare them honestly - from an implementation cost perspective, not a vendor's marketing.
