Discuss Your Project5+ Experience Years
Works across both sides of a Magento 2 or Adobe Commerce store. Proficient in PHP, Magento's module architecture, and theme development. Builds a custom extension and the frontend UI that uses it handles admin configuration and third-party integrations without splitting the work across two specialists.
7+ Experience Years
Senior-level builds covering complex B2B module customisation, GraphQL API development, multi-store configuration, cloud deployment, and Hyvä or headless frontend integration. These developers have the architectural depth to design the system correctly from the start and deliver it to Adobe's published standards.
3+ Experience Years
Handles the Liquid-based storefront and the Shopify API and Functions layer that drives backend logic. Builds custom themes, creates Shopify apps, configures integrations with external systems, and handles Shopify Plus setups. The right choice for a complete build or full rebuild handled by one person.
5+ Experience Years
Works at the PHP and theme level for WooCommerce stores, building both the storefront and the backend logic that powers it. Creates custom WooCommerce plugins, handles payment and shipping integrations, builds product templates from scratch, and manages the WordPress database layer.
5+ Experience Years
Builds decoupled architectures where a React or Next.js frontend connects to a Magento, Shopify, or WooCommerce backend via GraphQL or REST APIs. Writes the queries, builds the component library, manages frontend state, and ensures the backend exposes data in the right shape. One developer, both layers.
7+ Experience Years
For complex projects that need technical planning before code starts. Our architects assess the current setup, design the full-stack architecture, and oversee the build from both sides. They identify the decisions that are expensive to reverse before the development team makes them.
What's Included When You Hire Full Stack
From database architecture and backend logic through to theme development and storefront performance, built from scratch on your chosen platform. One developer owns every layer, so the build is consistent from start to finish, with no version mismatches between frontend and backend.
Bespoke Magento modules, Shopify apps, and WooCommerce plugins built to your requirements. Not off-the-shelf components adapted to fit, but written specifically for what your store needs, documented clearly, and built to a standard the next developer can read without a guided tour.
Payment gateways, ERP connections, CRM systems, shipping providers, and marketplace channels are handled across both the frontend and backend. Our full-stack developers integrate cleanly, with no coupling that breaks on the next platform update or makes future development harder to manage.
Moving between platforms requires rebuilding the frontend and backend in parallel. With one full-stack developer owning both, there is no handoff risk between separate teams working on different layers at different paces. The rebuild happens as one coordinated piece of work.
Performance problems on eCommerce stores often cross the frontend-backend boundary. Our developers identify and fix issues at every layer, from database query optimisation and slow API responses to frontend asset loading and Core Web Vitals, without needing separate specialists.
Decoupled architectures where a React or Next.js frontend connects to a Magento or Shopify backend via GraphQL or REST APIs. One developer writes both the query layer and the component library, which removes the communication gap that makes headless projects slow to build.
Every point below is backed by a certification, a named process, or a specific outcome. Generic agency claims are not useful when one developer is accountable for your entire store.
Our full-stack developers hold official Adobe Commerce certifications and Shopify Expert status credentials awarded by the platforms themselves, not self-declared. A full-stack developer who is certified on your specific platform knows how it works at the architecture level, not just the surface.
Our founder holds Magento Master recognition, awarded by Adobe to fewer than 60 developers globally. That depth of platform thinking shapes how our full-stack developers approach architecture decisions, module design, and code standards on every Magento and Adobe Commerce project.
Every build is written for your store. Our full-stack developers do not start from a premium theme, apply your brand, and call it custom. The codebase is yours, built to platform standards, documented clearly, and structured so the next developer who touches it can understand it.
We work as the white-label full-stack partner for digital agencies across the UK. No KiwiCommerce references appear in code, commit history, or documentation. Your client sees your name and your standards on everything. NDAs are signed before any work starts, on every engagement.
Your full-stack developer owns both the frontend and backend deliverables against a single fixed timeline agreed before work begins. Progress is reported against those milestones. If something slips, you hear from us before you have to ask. There is no separate frontend and backend schedule to reconcile.
Every full-stack developer on your project is based in the UK. What you ask for in a brief reaches the person building it directly, no intermediary, no overnight delay, no translation of requirements between account management and a remote team on a different working day.

A full stack developer works across both frontend and backend development. They can build user interfaces, develop server-side functionality, manage databases, create APIs and handle integrations required for an ecommerce platform.
Hiring full stack developers gives you access to professionals who can work across the complete technical stack. This can simplify development, reduce communication gaps between frontend and backend work, and provide a more consistent approach to building and maintaining your ecommerce platform.
Yes. You can hire a dedicated full stack developer to work exclusively on your project and collaborate with your internal team. This model can be suitable for businesses that need ongoing development, support, feature implementation or long-term ecommerce improvements.
Yes, you can hire remote full stack developers to work as an extension of your existing team. Remote developers can collaborate through your preferred communication and project-management tools while handling frontend, backend and integration requirements.
The technology stack depends on your project requirements. A full-stack developer may work with frontend frameworks, backend languages, databases, APIs, cloud services and ecommerce platforms to create a complete solution tailored to your business.
You can share your project requirements, technical needs and preferred engagement model with Kiwi Commerce. Our team can help you identify the right full stack developer or development team based on your ecommerce requirements and project scope.
Yes. Fixed-scope projects, such as a single store build, a platform migration, or a performance overhaul, are taken on alongside longer retainer arrangements. Scope, timeline, and cost are agreed upon before work starts. If requirements change during the build, adjustments are discussed openly rather than treated as a reason to renegotiate the whole agreement.
Retainer-based support is available covering ongoing feature development, platform updates, performance monitoring, and issue resolution. Currently, we support over 100 live stores on retainers, many with the same full-stack developer who built the original project. You get continuity rather than a new developer starting from scratch every time something needs attention.
Our UK-based certified full stack team is ready to look at your project. Get in touch today and we will respond within one business day with an honest assessment and a clear proposal covering both the frontend and backend scope.
