Frontend work decides whether a visitor buys or leaves. When you hire frontend developers from KiwiCommerce, you get certified specialists who build for performance and conversion on Magento, Hyvä, Shopify, and WordPress, not a generalist spread across every framework. Hyvä Bronze Partner. Adobe Commerce Certified. UK-based.
Most frontend developers work across marketing sites, SaaS dashboards, and apps. Ours do not. Every developer on our team has worked exclusively on eCommerce storefronts. That focus changes the quality of every decision they make.
Get In TouchHyvä replaces Magento's slow default stack. We are an official Hyvä Bronze Partner, one of the very few UK agencies, and we build it properly, not approximately.
Poor LCP and CLS scores cost you rankings before a customer sees your product. Our developers treat Core Web Vitals as a deliverable, not an afterthought.
We optimise at the component level, category renders, filter interactions, add-to-cart flows, not just overall page weight. The places that actually lose sales.
Over 60% of eCommerce traffic is mobile. Our developers build mobile-first as a technical decision, not a retrofit done after the desktop build is finished.
A shopper lands on your store with intent. What happens in the next three seconds, page load, product clarity, and navigation confidence, is entirely frontend. Get it wrong, and paid traffic becomes a cost with no return.
The difference between a strong eCommerce frontend and a poor one is rarely visible in screenshots. It shows up in Core Web Vitals reports, session recordings, and checkout abandonment data. A developer who has not built for eCommerce specifically will not know where those problems sit before they happen.
Our frontend developers work exclusively on eCommerce stores: Magento, Hyvä, Shopify, and WordPress. As an official Hyvä Bronze Partner, we build Hyvä themes that routinely achieve Lighthouse scores above 90, up from the 30–40 range typical of legacy Magento frontends. That is not incidental; it is the result of knowing the framework properly.
From pixel-accurate UI builds from Figma files through to headless React frontends connected to Magento or Shopify backends, the work is specific to what your store needs, built to a standard that another developer can maintain.

Works at the theme and PHP template level rather than assembling pages from Gutenberg blocks or page builders. Builds WooCommerce storefronts that are fast, technically clean, and designed for conversion.
5+ Experience Years
Works directly from Figma, Sketch, or Adobe XD files and delivers pixel-accurate, responsive implementations across all screen sizes, including interactions, hover states, and performance characteristics, not just visual appearance.
What's Included When You Hire From Us
Every theme is written for your store on Magento, Hyvä, Shopify, Liquid, or WordPress. No starter templates with your brand colours applied on top. The codebase is yours, documented, and built to a standard that another developer can read without a guided tour.
As a certified Hyvä Bronze Partner, we build high-performance Magento frontends using the Hyvä framework properly. This covers new Hyvä builds and migrations from slow legacy Magento themes. Lighthouse scores above 90 are a typical outcome, not a best-case one.
We fix Core Web Vitals issues, reduce page weight, and resolve mobile rendering problems that cost conversion. Work is targeted at the specific bottlenecks your store has, not a generic audit checklist delivered as a report with no implementation.
We take Figma and Adobe XD files and build them into responsive,pixel-accurate code. Interactions, hover states, mobile layouts, and edge cases are included. What you signed off on in the design tool is what goes live on the store.
Connecting your storefront to third-party APIs, payment providers, loyalty platforms, or headless backends. Our developers handle integration work cleanly, without coupling that breaks on the next platform update or makes future development harder.
Ongoing frontend development for stores that need continuous improvement after launch. We currently support over 100 live stores on active retainers covering new feature development, performance monitoring, and bug fixes. The work does not stop at go-live.
These are not generic agency promises. Each point below has a specific reason it appears on this page is a certification, a process, or a measurable result that backs it up.
Very few UK agencies hold official Hyvä Bronze Partner status. Ours was awarded by Hyvä, not self-declared. Our Hyvä builds follow the framework correctly and deliver the performance results Hyvä was designed to produce. Lighthouse scores above 90 are a standard outcome on our builds.
Adobe Commerce certification is an official credential from Adobe, not a course completion badge. Our certified developers have demonstrated platform-level knowledge that qualifies them to build on Adobe Commerce correctly. That depth shows up in frontend work that doesn't create technical debt downstream.
Our frontend developers build within Magento's theme hierarchy, Hyvä's Alpine.js and Tailwind patterns, and Shopify's Liquid architecture, not around them. Code that works around the platform creates problems with updates. We document everything so any developer can continue the work.
We work as the white-label frontend partner for digital agencies across the UK. Your clients see your name throughout. No Kiwi Commerce references appear in code, commit history, or documentation. NDAs are signed on every engagement before work begins.
You receive a delivery timeline with defined stages before a single line of code is written. Progress is reported against those milestones. If a stage changes, you hear about it from us before you have to ask.
Every frontend developer on your project is based in the UK. Calls happen at normal working hours. Questions are answered the same day. What you ask for in a brief is what gets built, there is no intermediary translating requirements between you and the person doing the work.

A frontend developer specialises in everything a customer sees and interacts with, page layouts, product display, navigation, checkout flow, and the code that controls performance across every device. A full-stack developer covers both frontend and backend, but rarely with the same depth on either. For eCommerce stores where Core Web Vitals, mobile performance, and checkout conversion are critical metrics, a dedicated frontend specialist produces better results than a generalist split across both layers. Our developers work exclusively on eCommerce storefronts, so platform-specific performance challenges aren’t new problems for them.
In most cases, within one to two weeks of agreeing scope. We confirm developer availability and a start date within one business day of your enquiry. A fixed timeline with defined milestones is agreed before any work begins, you know exactly what is being delivered and when from day one.
Yes. We carry out a review of the existing theme and codebase before starting to identify technical problems and agree on a clear scope. We don’t make assumptions about the state of the existing code, standards, documentation, and technical debt, which vary significantly between projects. Work begins only once both parties have agreed on exactly what is being fixed, improved, or built. This prevents scope creep and gives both sides a shared definition of what is done.
Our developers are UK-based and work remotely as standard. You get full UK timezone availability, daily communication, and a certified team without the overhead of an on-site resource. There is no communication lag, no overnight handoff, and no translation layer between you and the developer doing the work. If a project has a specific requirement for on-site presence at any stage, we can discuss that separately.
All code is documented and handed over to your team. You own it outright, there’s no dependency on us to maintain it. If you need ongoing support, we offer retainer-based development covering new feature work, performance monitoring, and bug fixes. We currently support over 100 live stores on active retainers. The option is available if you need it, but there’s no obligation to continue beyond the original project scope.
Both models work. We take on fixed-scope projects, a single theme build, a performance optimisation sprint, a Figma-to-code handoff, as well as longer retainer and dedicated team arrangements. The scope, timeline, and cost are agreed before work starts in either case. There is no minimum commitment required for project-based work.
Our UK-based certified frontend 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.
