Some projects need a specialist. Others need someone who can own the entire build. When you hire full-stack developers from KiwiCommerce, you get certified eCommerce professionals who handle both sides of your store, the storefront your customers see and the server-side logic that makes it work. One developer, complete ownership, no gaps between frontend and backend.
A full-stack developer makes the most sense in specific situations. If you need one person who can take a project from brief to launch without handoffs between teams, or if your project is too tightly integrated for frontend and backend to operate as separate workstreams, that is where our full-stack team delivers.
Get In TouchYou need a complete store built, and you want one developer who owns it from the database to the storefront. No passing work between teams. No version mismatches. One person is accountable for the full build and works to a fixed timeline.
You have a client project that requires a full-stack resource, delivered quietly under your brand. Our full-stack developers work as your white-label development partner. Your client sees your name and your standards on everything we build.
Moving from one platform to another requires rebuilding everything at once. Theme, backend logic, integrations, data layer. A full-stack developer who understands the whole system handles this more efficiently than separate specialists working in parallel.
You do not have the budget for a frontend team and a backend team. A certified full-stack developer lets you build a production-ready eCommerce store with one person who understands the entire project and can make sensible technical decisions across all of it.
A full-stack developer is not a generalist who knows a bit of everything. On eCommerce projects, they need genuine depth on both sides of the store: the frontend layer that customers interact with and the backend systems that process every action a customer takes. Without that depth, you get a developer who is competent on one side and cutting corners on the other.
Our full-stack developers are eCommerce specialists first. They have built stores on Magento, Adobe Commerce, Shopify, and WordPress from the ground up, and they understand what each platform requires at every layer. When one developer owns the full build, you get consistency in code quality, faster decision-making, and a single point of accountability for everything from how a product page renders on mobile to whether the order data is reaching your ERP correctly.
Here is what they handle:
5+ Experience Years
Works across both sides of a Magento 2 or Adobe Commerce store. Proficient in PHP, Magento's module architecture, and LESS-based theme development. These developers can build a custom extension and the frontend UI that uses it, handle the admin configuration, and integrate third-party services without splitting the work between separate specialists. Ideal for mid-sized Magento projects where one person owns the full build, which improves both speed and consistency.
7+ Experience Years
For enterprise-level Adobe Commerce builds that require expertise across the entire platform. These senior developers handle complex B2B module customisation, GraphQL API development, multi-store configuration, cloud deployment, and Hyvä or headless frontend integration. They have the architectural depth to design the system correctly from the start and the development experience to deliver it to Adobe's standards.
3+ Experience Years
Handles both the Liquid-based storefront and the Shopify API and Functions layer that drives backend logic. These developers build custom themes, create Shopify apps, set up integrations with external systems, and handle Shopify Plus configurations. They understand the full extent of what Shopify allows and how to work creatively within it. Ideal for Shopify and Shopify Plus stores that need a complete build or rebuild handled by one person.
5+ Experience Years
Builds decoupled eCommerce architectures where a React or Next.js frontend connects to a Magento, Shopify, or WooCommerce backend through APIs. These developers are comfortable writing the GraphQL queries, building the component library, managing state on the frontend, and ensuring the backend is exposing data in the right shape. They suit brands moving to headless commerce who want a single developer managing both sides of the architecture.
5+ Experience Years
Works at the PHP and theme level for WooCommerce stores, building both the storefront and the backend logic that powers it. These developers create custom WooCommerce plugins, handle payment and shipping integrations, build product page templates from scratch, and manage the WordPress configuration and database layer. Suitable for content-heavy or mid-sized eCommerce stores where WordPress is the right platform.
7+ Experience Years
For complex projects that need proper technical planning before any code is written. Our solution architects assess your current setup, identify what needs to change, and design the full stack architecture before the development team begins. They own the technical direction of the project, oversee the build, and ensure both frontend and backend are built to a standard that supports long-term growth without accumulating technical debt.
Our full-stack developers do not hold general web development credentials. They hold official Adobe Commerce certifications and Shopify Expert status. They have been tested on the platforms they work with, not just experienced. That distinction matters when your entire store depends on one developer getting both sides right.
Every developer on your project is based in the UK. When something needs attention, you reach a person who is working at the same time as you, understands the UK market, and can respond that day. There are no time zone gaps and no overnight delays between a question and an answer.
Our founder holds Magento Master recognition, awarded by Adobe to fewer than 60 developers globally. That standard of technical thinking shapes how our full-stack developers approach architecture decisions, platform standards, and code quality across every project we take on.
Our full-stack developers write code for your store. They do not start from a premium theme, drop in a page builder, and call it custom work. Every build is written to platform standards, structured clearly, and documented so that anyone who works on it afterwards can understand what was built and why.
Your codebase, your client relationships, and your business logic stay with you. We sign non-disclosure agreements on every engagement as standard. If you are an agency using us as your white-label full-stack team, we remain completely invisible. No KiwiCommerce references in code, commits, or any documentation.
With a full-stack developer, there is one person responsible for the entire build. No gaps at the handoff between frontend and backend. No blame shifting between teams when something breaks across the stack. One developer, one timeline, one clear set of milestones agreed before work starts.
