Magento development

Custom Magento development without turning the platform into technical debt.

We build and improve Magento Open Source functionality for established stores, complex commerce workflows and integration-heavy environments. The objective is not simply to make a feature work today; it is to implement it in a way that can be tested, upgraded and supported later.

The bigger picture

Start with the business and technical reality

Magento offers many extension points, which makes it possible to solve complex business requirements cleanly — or to create brittle customisation that becomes expensive at every upgrade. We pay close attention to dependency boundaries, Magento service contracts, plugins, observers, cron, queues and data models so custom behaviour remains understandable.

Before changing a mature store we review the current implementation. Two stores on the same Magento version can have very different risk because one may be close to core while another depends on dozens of extensions, rewrites and external integrations. That context determines the safest approach.

Development can include a complete workstream or additional specialist capacity inside an existing Magento team.

Typical situations

When clients bring us in

  • Generic extensions cannot represent the required business rule
  • Custom checkout, account or admin workflows need deeper engineering
  • Legacy modules are difficult to maintain or upgrade
  • The store needs new integrations with internal systems
  • A backlog requires additional Magento capacity
  • A major platform change needs experienced review before release
The objective

What good delivery should leave behind

A successful engagement should improve more than the immediate feature or incident. It should make the system easier to understand, safer to change and more visible to the people responsible for operating it.

  • Clear technical ownership and responsibilities
  • Maintainable code and configuration
  • Visible failures rather than silent data loss
  • Controlled release and recovery paths
  • Documentation for future developers and operators
  • A sensible next-step roadmap rather than permanent firefighting
What the work covers

Technical depth across the parts that matter

The exact scope depends on the existing environment and commercial priorities. We focus on the areas that materially affect reliability, maintainability and delivery rather than adding process for its own sake.

Custom modules

Purpose-built modules with clear responsibility and configuration rather than unnecessary core modification.

Backend services

Business logic, repositories, plugins, events, scheduled jobs, queues and admin functionality.

Storefront engineering

Theme and frontend work that respects performance, accessibility and upgradeability.

Checkout & accounts

Custom purchasing, validation, payment, delivery and customer-account workflows.

Integration code

APIs, imports, exports, webhooks, queues and scheduled synchronisation.

Technical debt

Refactor fragile customisation and remove obsolete dependencies that slow future delivery.

Problems we look for

Common failure patterns that create unnecessary cost

Many technical problems are recurring patterns rather than isolated defects. Identifying them early helps avoid repeatedly paying to treat the visible symptom.

  • Core overrides making upgrades risky
  • Business rules duplicated between extensions
  • Cron jobs with no failure visibility
  • Large observers or plugins creating hidden side effects
  • Frontend customisation causing excessive JavaScript or layout overhead
  • Custom code relying on undocumented external behaviour
How we work

A controlled route from uncertainty to production

We prefer visible, reviewable delivery. The exact sequence changes with the project, but the principle is to reduce uncertainty early and keep each production change understandable.

01Review the existing implementation
02Define business rule and acceptance criteria
03Choose the cleanest Magento extension point
04Develop with logging and testability
05Regression-test related platform journeys
06Deploy and observe production behaviour
Engineering judgement

Technology is part of the answer, not the starting question

Good Magento development requires understanding the platform around the feature: cache, indexes, database writes, scheduled processing, API consumers and deployment. We avoid treating code as isolated because production impact often appears in these neighbouring layers.

Where specialist capability comes from our wider engineering team, we are transparent about the proposed delivery model and match the person or team to the actual requirement rather than presenting a long list of technologies as if every project needs all of them.

Delivery models

Use the level of ownership that fits your team

Defined project

Midoriweb owns an agreed scope with clear milestones, acceptance criteria and release responsibilities.

Specialist workstream

Bring us into one technically difficult area while your existing team or agency owns the wider programme.

Team augmentation

Add developers to your existing process for a fixed period or an ongoing roadmap.

Ongoing technical partner

Combine support, maintenance, monitoring and planned improvement under continuing technical ownership.

Frequently asked questions

Questions worth answering before work starts

Do you build custom Magento modules?

Yes. Custom modules are appropriate when business rules cannot be implemented cleanly with configuration or a suitable existing extension.

Can you refactor existing custom modules?

Yes. We can review maintainability, dependencies and upgrade risk and then improve the highest-risk areas.

Can you work on frontend and backend?

Yes. Work can include themes, checkout, backend logic, integrations and performance.

Do you modify Magento core files?

We avoid core modifications. Custom behaviour should use supported Magento extension mechanisms wherever possible.

Can you work with third-party extensions?

Yes. We can configure, integrate, extend or replace them depending on the quality of the extension and the requirement.

Can development be supplied as dedicated capacity?

Yes. Magento developers can be engaged for an ongoing backlog or a defined project.
