What does Magento development involve?

Magento development covers custom modules, integrations, frontend, extensions, fixes and support and tracking built in. Magento is powerful and complex. Anthony McGrath does the work himself, with 22 years in digital marketing, for businesses in the UK, the US, Dubai and Australia.

Why Magento needs a specialist

Magento is powerful and complex. Stores often carry years of extensions, overrides and quick fixes that make every change slow and every upgrade risky. Generalist developers can make it worse.

I work with Magento the way it is meant to be built: proper modules, dependency injection, plugins instead of overrides, version control and automated deployment. The result is a store that is faster to change and safer to upgrade.

Questions

How much does a Magento developer cost?

Smaller jobs are fixed-price. Bigger projects are planned and priced in stages, so you know the cost before work starts.

Do you work on Adobe Commerce as well as Magento Open Source?

Yes. Both, including Adobe Commerce Cloud deployments and B2B features.

Can you take over from another agency?

Yes. I start with an audit of the code, extensions and hosting, so you know exactly what you have and what needs attention.

Should we stay on Magento?

Magento suits large catalogues, complex pricing and B2B. If another platform would serve you better, I will say so honestly.
