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.
Discuss Frontend Project5+ Experience Years
Builds Hyvä themes from scratch and migrates stores from legacy Magento frontends. Certified through KiwiCommerce's official Hyvä Bronze Partnership. Typical outcomes include the Lighthouse score improvements from the 40s to above 90, with measurable improvements to LCP and CLS.
3+ Experience Years
Proficient in Magento's theme hierarchy, LESS/SASS, KnockoutJS, and the Magento UI component library. Builds within Magento's frontend architecture properly, category page layouts, custom widgets, and performance fixes on live Adobe Commerce stores, not around it.
3+ Experience Years
Shopify's Liquid templating language is straightforward to learn but specific to master at scale. Our Shopify frontend developers handle custom theme builds, custom section development, Hydrogen headless builds, and Shopify Plus storefront performance work for mid-to-large retailers.
5+ Experience Years
Builds custom React frontends connecting to Magento, Shopify, or WooCommerce backends via APIs. For brands moving to headless or composable commerce architecture who need the performance and flexibility of a decoupled storefront without losing depth of platform features.
3+ Experience Years
Works at the theme and PHP template level rather than assembling pages from Gutenberg blocks or page builder components. Builds WooCommerce storefronts that are fast, technically clean, and designed for conversion with the code quality to prove it.
5+ Experience Years
Works directly from Figma, Sketch, or Adobe XD files and delivers pixel-accurate, responsive implementations across all screen sizes. Closes the gap between design intent and live code, completely including the visual, the interactions, and the performance characteristics.
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. That means 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, not an exception.
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 does not 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. Code that follows it does not. 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 KiwiCommerce references appear in code, commit history, or documentation. NDAs are signed on every engagement before work begins, with no exceptions.
You receive a delivery timeline with defined stages before a single line of code is written. Progress is reported against those milestones, not described vaguely in a monthly update. If a stage slips, 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 get 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 builds and maintains everything a customer sees and interacts with: page layouts, product display, navigation, checkout flow, and the code that controls performance on every device. On eCommerce stores specifically, they own Core Web Vitals, mobile responsiveness, and page speed, all of which affect how many visitors complete a purchase.
eCommerce frontends have specific challenges a general web developer will not naturally know: category page rendering at scale, product filter performance, add-to-cart edge cases, and checkout flow optimisation. Our developers work exclusively on eCommerce stores, so these are not problems they encounter; they are problems they have already solved.
Hyvä is a modern frontend framework for Magento that replaces the default theme stack. Stores on the default Magento frontend typically score 30–40 on Lighthouse. Hyvä routinely reaches above 90. Faster load times, better Google rankings, and lower bounce rates follow. As an official Hyvä Bronze Partner, we build Hyvä properly and manage the migration.
Yes. Before starting, we carry out a review of the existing theme and codebase to identify technical problems and agree on a clear scope. We do not make assumptions about the state of the existing code. Work begins only once both sides have agreed on exactly what is being fixed, improved, or built.
A Hyvä build on an existing Magento store usually takes six to twelve weeks. A Shopify theme for a mid-sized retailer typically takes four to eight weeks. Complex enterprise builds take longer. A fixed timeline with defined stages is agreed upon before work begins, so you always know when delivery is expected.
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. If your project requires physical presence at any stage, we can discuss that separately.
Yes. We take on fixed-scope projects, a single-theme build, a performance audit with implementation, or a design-to-code sprint, as well as longer retainer arrangements. The scope, timeline, and cost are agreed upon before work starts. If your needs change, we discuss scope adjustments openly rather than treating them as an automatic extra cost.
We offer retainer-based support covering ongoing improvements, new feature development, performance monitoring, and bug fixes. Currently, we support over 100 live stores on retainers. The option is always available if you need it, but there is no obligation to continue with us after a project is signed off.
