What Makes a Magento Expert?
Magento is not a generic PHP codebase. It has its own dependency injection container, plugin and observer system, layered configuration, cache stack, indexer framework, release cadence, and a platform-specific set of pitfalls that only become visible weeks after a change ships. A true Magento expert combines deep familiarity with those internals with hands-on production experience across multiple live stores.
At Interjar every developer works exclusively on Magento 2 and Adobe Commerce. Between us we hold current Adobe Commerce Developer, Adobe Certified Professional, and Adobe Certified Expert credentials, and we have upgraded, rescued, migrated, and re-platformed more Magento stores than we can count. If you are looking for a Magento specialist rather than a generalist who happens to have touched Magento once, you are in the right place.
How Our Magento Experts Help Merchants
From one-off fixes to full managed service, our UK Magento developers cover every part of running a Magento 2 or Adobe Commerce store in production.
Magento Specialists, UK-Based
Interjar is a specialist Magento agency in Chester, serving clients across London, Manchester, Birmingham, Leeds, Bristol, Edinburgh, and the rest of the UK and Ireland. Every developer is employed directly, UK-based, and works exclusively on Magento and Adobe Commerce, no rotations onto WordPress, Shopify, or generic PHP projects. That focus is how our Magento specialists stay genuinely current on the platform rather than drifting into shallow familiarity.
When you hire Magento specialists from Interjar you get a team of senior developers covering development, infrastructure, security, and complex integrations. Day-to-day communication is direct to the developers writing your code, with an account manager handling commercial matters in the background, so technical context never gets lost in translation.

How We Work With You
Every engagement with our Magento experts follows a simple, transparent process. No drawn-out discovery phases, no surprise change requests, and no scope creep.
In-House UK Experts vs Offshore Development
Offshore development quotes often look attractive on the surface, but the total cost of a Magento project includes code quality, communication overhead, bug-fix turnaround, and the hidden tax of re-doing work that was almost right. Our UK Magento experts run every engagement end-to-end, so there is no hand-off layer between your brief and the code in production.

Magento Experts FAQs
- What makes a Magento expert?
- A Magento expert combines deep platform knowledge with production experience. At Interjar this means Adobe-certified developers with 15+ years of Magento and Adobe Commerce experience, contributing back to the platform, and running live stores through multiple major version upgrades, PHP migrations, and Black Friday peaks.
- Are your Magento developers based in the UK?
- Yes. Every Magento developer at Interjar is UK-based and employed directly. No offshore teams, no third-party contractors, no outsourcing. Our office is in Chester and we work remotely with clients across the UK and Europe.
- What does Adobe Silver Solution Partner mean?
- Adobe Silver Solution Partner is a verified partnership tier in the Adobe Solution Partner Programme. It requires active Adobe Commerce certifications, proven client results, and ongoing platform contributions. It gives us direct access to Adobe engineering support and early visibility of platform roadmap changes.
- How do I hire a Magento specialist?
- Most engagements start with a scoping call. We review your current store, discuss what you need, and send a written scope with an hourly estimate. Work is billed at £100/hr to the minute. There is no minimum commitment and no lock-in, so you can start with a small fix and scale up as trust builds.
- Can a single Magento expert handle my store, or do I need a full team?
- Most Magento stores are best served by a small team of senior developers covering development, infrastructure, security, and integrations. Interjar assigns a team of senior developers to your store, supported by an account manager for commercial matters, with day-to-day communication going direct to the developers.
- What is the difference between a Magento expert and a general web developer?
- Magento is a complex, opinionated platform with its own service contracts, plugin architecture, caching layers, indexing system, and release cadence. A general web developer can read the code, but without Magento-specific experience they tend to create problems that only surface weeks later in production. Every Interjar developer works exclusively on Magento and Adobe Commerce.
- Do you work with Adobe Commerce as well as Magento Open Source?
- Yes. As an Adobe Silver Solution Partner we work daily with both Adobe Commerce (formerly Magento Commerce) and Magento Open Source. We can also advise on whether the licence cost of Adobe Commerce is justified for your business versus Open Source with custom B2B or performance work.
- How quickly can a Magento expert start work?
- For urgent issues we can usually begin diagnostic work the same day. For new engagements we typically onboard within one to two business days: repository access, environment review, and a kick-off call to align on priorities.
- What do UK Magento experts cost?
- Interjar charges a flat £100/hr for every Magento developer. There are no tiered rates, no minimum retainers, and no charges for account management. Billing is to the minute with detailed time logs against every task.
