ERP and inventory synchronisation
Agree which system owns each field, how often data updates and what happens on failure. One useful acceptance check is sending the same update twice and verifying that stock or orders are not duplicated.
Magento 2 & Adobe Commerce
Magento 2 modules and integrations.
Magento 2 development for custom modules, checkout and ERP/PIM integrations. Work directly with Jonas Stenild in Denmark. The scope follows your Magento Open Source or Adobe Commerce version and the extensions already in your shop.
Magento 2 development with clear acceptance criteria
Start with one specific workflow. These examples show how I scope a task and what we can use to accept the delivery.
Checkout and business rules
Describe the specific rule for pricing, customer groups or delivery. Test both the order that should succeed and the situation that should be rejected in your actual checkout.
Modules and administration
Define the fields, permissions and staff workflow. Acceptance can include staging installation, permission checks and a plan for rolling the change back.
Experience and code you can assess
My Magento 2 experience forms part of my work as a developer at Matas. Read about my background and employment. That employment is separate from my freelance projects.
For an example of how I document my own extensions, read the technical case about my Shopware plugin. It covers decisions about events, data and failure cases, with published test results. It is a Shopware case; compatibility and tests for your Magento installation are scoped separately.
You receive the agreed module or integration work, code in your repository, relevant test results and installation and operation notes. Price, schedule and ongoing maintenance are agreed around the task. Explore agency and development team collaboration.
Why Magento 2
Complex commerce. A solid foundation.
Magento 2 and Adobe Commerce power some of the largest online stores in the world. Here's why it remains a top choice for serious e-commerce businesses.
Enterprise-Grade Architecture
Built to handle millions of products, complex catalogs, multi-store setups, and high-volume traffic. Magento 2's modular architecture scales with your business without compromise.
Highly Customizable
Every aspect of the platform can be extended through modules - from storefront layouts and checkout flows to admin panels and API endpoints. No vendor lock-in, no restrictions on what you can build.
Adobe Commerce Ecosystem
Backed by Adobe, the platform benefits from a massive ecosystem of extensions on the Adobe Commerce Marketplace, a global developer community, and enterprise support options for mission-critical stores.
What I Build
Complexity in. Clarity out.
Modules and integrations for the parts of your Adobe Commerce or Magento 2 store that need specialist attention.
Custom Modules
Bespoke Magento 2 modules built to your exact specifications. Whether it's a new storefront feature, a backend automation, or a data processing pipeline - I build it from scratch following Magento's architecture patterns.
Checkout Customization
Custom checkout steps, field validation, shipping method logic, order processing rules, and post-purchase flows. I modify and extend Magento's checkout to match your exact business requirements.
Admin Panel Extensions
Custom admin grids, forms, dashboards, and reporting tools. I extend the Magento 2 admin panel with UI components that give merchants full control over their store data and operations.
Payment Integrations
Payment modules and PSP integrations scoped around the provider’s supported integration flow. We agree requirements for subscriptions, currencies, payment status and order handling, then test the relevant scenarios.
ERP/CRM Connectors
Bidirectional integrations between Magento 2 and your ERP, CRM, PIM, or warehouse management system. Real-time sync of orders, inventory, customers, and product data via REST or message queues.
Performance Optimization Modules
Custom caching layers, index optimization, lazy loading, queue-based processing, and database tuning modules. I build solutions that keep Magento 2 stores fast under heavy catalog and traffic loads.
GraphQL API Extensions
Custom GraphQL resolvers, schema extensions, and API endpoints for headless Magento 2 storefronts. I extend the Magento GraphQL layer to expose any data your frontend or mobile app needs.
Technology Stack
Magento architecture. Properly connected.
Service contracts, APIs and message queues connect your storefront, platform and business systems.

Development Process
From technical brief to production.
Understand the setup. Build, test and deploy. Keep improving. Open each step for the technical details.
SELECT A STEP TO READ MOREDiscovery & Scoping
I start by understanding your business requirements, existing Magento setup, and the problem the module needs to solve. This phase produces a clear scope, technical specification, and timeline.
- Requirements gathering
- Technical feasibility analysis
- Architecture planning
- Scope & timeline agreement
Development & Testing
I build the module following Magento 2's coding standards, using proper dependency injection, service contracts, and plugin/observer patterns. Every module is tested with PHPUnit and integration tests.
- Magento 2 coding standards
- Unit & integration testing
- Code review & quality checks
- Iterative development with demos
Deployment & QA
Rigorous testing on staging environments that mirror your production setup. I verify compatibility across Magento versions, run performance benchmarks, and conduct security audits before go-live.
- Staging environment validation
- Cross-version compatibility
- Performance benchmarking
- Security review
Maintenance & Support
Ongoing support to keep your module running smoothly. I handle Magento version upgrades, PHP compatibility updates, bug fixes, and feature enhancements as your business evolves.
- Magento version upgrade support
- PHP compatibility updates
- Bug fixes & security patches
- Feature enhancements
Planning a Magento 2 development task?
Your installation
Include your Magento Open Source or Adobe Commerce version, PHP version and relevant extensions. Mention any custom checkout or separate frontend so compatibility can be assessed.
The workflow to improve
Describe one concrete problem and the expected result. For an integration, identify the systems, source of truth, data direction and what should happen when a sync fails.
Testing and release
Identify the staging environment, the people who will review the change and any launch deadline. We agree acceptance checks, deployment, rollback and handover before development.
Do you support both Magento Open Source and Adobe Commerce?
Yes. I work with Magento Open Source and Adobe Commerce. We agree the supported edition and versions before development. Commerce-specific features such as B2B or content staging are assessed separately; support for the other edition is not automatic.
Can you help migrate from Magento 1 to Magento 2?
Absolutely. I have deep experience in both Magento 1 and Magento 2 architectures. I can assess your current Magento 1 setup, plan the migration strategy, rebuild custom modules for Magento 2's new architecture, migrate data, and ensure a smooth transition with minimal downtime.
Do you build headless Magento 2 storefronts?
Yes. I extend Magento 2's GraphQL API layer with custom resolvers and schema to support headless frontend frameworks like React, Vue.js, or PWA Studio. This includes custom queries, mutations, and caching strategies for performant decoupled commerce experiences.
How do you handle Magento 2 performance challenges?
Performance is a priority in every module I build. I use proper indexing, caching strategies (Varnish, Redis, built-in full-page cache), lazy loading, and asynchronous processing via message queues (RabbitMQ). For existing stores, I audit slow queries, optimize custom code, and implement targeted performance improvements.
Other Platforms
I also build plugins for these platforms
