HIRE WITH US
Kultrix UI/UX developers live at the intersection of design craft and engineering rigour. They read Figma files as fluently as they write TypeScript, implement pixel-perfect interfaces in React, and enforce accessibility standards from day one.

EXPERTISE
WHAT WE DO
We translate Figma designs into production-ready React components with pixel-level fidelity, responsive breakpoints, and clean, maintainable code.
We build and maintain Storybook-driven component libraries with design tokens, variant APIs, and documentation that keeps design and dev in sync.
We audit interfaces against WCAG 2.2 AA standards, fix keyboard navigation, aria attributes, colour contrast, and focus management across the codebase.
We implement micro-animations, transitions, and gesture-driven interactions using Framer Motion or CSS, improving perceived performance and user delight.
We build fluid layouts that work perfectly across all device sizes, from 320px mobile to 4K desktop, using utility-first CSS and systematic breakpoints.
We profile rendering bottlenecks, apply code splitting, optimise images, and eliminate layout shifts to meet Core Web Vitals targets for every page.

CASE STUDIES
Testimonials
What impressed us most was how Kultrix handled the full stack - frontend, backend, and mobile - with one cohesive team. Communication was clear, delivery was predictable, and the final product exceeded what we initially scoped.
Co-CEO
Kultrix built both our web platform and mobile app from scratch. Their team understood the complexity of our industrial workflows and translated them into clean, intuitive interfaces. We launched on time and our operators adopted the tools immediately.
Co-CEO
Kultrix handled everything for us - landing page, dashboard, mobile app, and even a Chrome extension. Having one team own the entire product surface meant everything felt connected and consistent. They shipped fast and the quality speaks for itself.
CEO, Ping Proxies
Kultrix has been our go-to partner for multiple projects - from marketing websites to full mobile applications and backend systems. They scale up when we need speed and maintain consistency across every project. Reliable, fast, and technically strong.
CEO, Volume Apps
Working with Kultrix on our mobile app and backend was seamless. They brought strong product thinking to every sprint, not just code. When priorities shifted, they adapted quickly without losing momentum. Exactly the kind of partner a product team needs.
Product Lead, Pelago
We needed a team that could handle mobile development, server infrastructure, and AI features all at once. Kultrix delivered on all three fronts. Our fitness platform went from concept to production in under four months with zero compromises on quality.

FAQ
A UI/UX developer is an engineer who specialises in building user interfaces that match design intent precisely. Unlike a pure UX designer who creates wireframes, or a general frontend developer who focuses on architecture, a UI/UX developer brings both - translating designs into accessible, animated, production-ready code. Kultrix UI/UX developers read Figma specs, implement component systems, and obsess over interaction quality.
Most Kultrix engagements start within 48 hours of contract signing. We keep a bench of vetted senior developers available for immediate placement. For larger teams or specialised requirements, a one-week lead time is typical.
Yes - collaboration with design is a core competency, not an afterthought. Our developers join Figma comments, participate in design reviews, flag implementation constraints early, and suggest component-level improvements that make the final product stronger. They are the bridge, not just the last step.
React and TypeScript are our primary stack for web UI. We also work with Vue.js, Svelte, and Angular when the project requires it. For design tooling, our developers work directly in Figma and can export code using Figma Dev Mode or implement manually for precise control.
Both options are available. You can hire a single embedded UI/UX developer to augment your existing team, or engage a Kultrix pod with a developer, designer, and QA for an end-to-end capability. We size the engagement to your actual need after a short scoping call.
We build accessibility in from the start rather than retrofitting it. Our developers follow WCAG 2.2 AA guidelines, test with screen readers (NVDA, VoiceOver), validate keyboard navigation flows, and run automated audits with axe-core in CI. Accessibility is treated as a functional requirement, not an optional extra.
Yes. UI logic is tested with React Testing Library, focusing on user behaviour rather than implementation details. Visual regression tests with Storybook and Chromatic catch unintended style changes across the component library. We configure these pipelines as part of onboarding.
Absolutely. Our developers are experienced with joining live codebases. They start with a code review, learn your conventions, align with your design system, and contribute productively within the first sprint. Onboarding friction is minimal.
We offer monthly retainer and time-and-materials models. Retainer engagements include a fixed allocation of developer hours per month with a guaranteed response SLA. T&M engagements are billed weekly against tracked hours. Both models include transparent timesheets and a dedicated account manager.
All Kultrix developers are mid-to-senior level with a minimum of four years of professional experience building production interfaces. We do not place juniors on client engagements. Every developer passes a technical interview and a practical coding assessment before joining our bench.
Yes. Fixed-scope projects (e.g., build a design system, implement a set of Figma screens, conduct an accessibility audit) are scoped after a discovery call and quoted with a fixed price and timeline. Scope changes are handled through a simple change-order process.
Kultrix is a product-focused agency, not a marketplace. Every developer is a Kultrix employee or long-term contractor, not an anonymous profile. We manage quality, handle replacements if something is not working, and provide a dedicated account manager. You get the flexibility of a freelancer with the accountability of an agency.
