Business owners implementing a Magento 2 store for the first time often do not know what to expect or what to prepare for. Below I describe the typical course of a project from the first conversation to launch – without embellishments.
A shop with 50,000 products – full reindex took 6 hours and often ended with a deadlock error. Product prices and availability were updating with a delay. Fix time: 1 day.
An online store processes customer personal data and payment card data. For attackers this is an attractive target. An attack does not always look dramatic – it is often invisible for weeks or months. A security audit is checking the state of the store before someone else does.
After migrating from Magento 1 to Magento 2, the shop lost 60% of organic traffic within 2 weeks. Ahrefs showed 4000 404 errors. Old product and category URLs were not being redirected. Fix time: 3 days.
Chain of Responsibility is a behavioural pattern in which a request passes through a chain of handlers – each can handle it, modify it, or pass it on. Ideal for multi-step validation, data processing pipelines and middleware. In Magento 2 this pattern is everywhere – in plugins, order pipelines and HTTP request handling. I show an implementation from scratch and three different chain variants.
Customers reported they couldn’t place orders – clicking “Place Order” reloaded the page and the cart was empty. Orders were not reaching the system. The problem only affected card payments, bank transfer worked. Resolution time: 4 hours.
Integrating a Magento store with an ERP, CRM or PIM system is one of the most common causes of budget and deadline overruns in e-commerce projects. Not because it is technically impossible – but because both parties (client and contractor) often underestimate its complexity at the quote stage.
The category page took 18 seconds to load with 200 products. PageSpeed score: 12/100. The problem was not the server or Varnish – it was in a module’s code that executed a separate SQL query for every product.
The shop stopped working immediately after running composer update. White screen or 500 error on the front and admin, logs full of PHP Fatal Error messages. Resolution time: 2 hours.
Warden and DDEV are the two most popular local development environment tools for Magento 2. DDEV focuses on simplicity and fast start – it works out of the box after installation. Warden gives full control over network configuration and certificates, but requires more knowledge of Docker Compose. In 2026 both are mature products. I show where each one shines and when to choose which.
