UI Development That Matches the Design, Every Time

UI development is the practice of implementing visual interface designs in production code. A UI developer works from Figma files and translates layouts, components, interactions, and animations into React (or other framework) components that are used in the live product. It is distinct from full-stack development in that it focuses specifically on the frontend presentation layer.

A frontend developer typically handles both the UI layer and frontend business logic - routing, state management, API integration. A UI developer specializes in the visual implementation layer: pixel-accurate components, responsive layouts, animations, and accessibility. We offer both, and our UI developers work alongside your backend team if needed.

Yes. We use a rigorous QA process comparing the implementation to the Figma design at each breakpoint using overlay tools. We address spacing, typography, color, shadow, and border-radius discrepancies before declaring a component complete. "Close enough" is not in our vocabulary.

We specialize in React and Next.js with TypeScript. For styling, we use Tailwind CSS as the primary system, with CSS Modules when component isolation requires it. For animations, we use Framer Motion for React-native transitions and GSAP for complex timeline and scroll-trigger animations.

Yes. Accessibility is a first-class requirement, not an afterthought. We use Radix UI headless primitives for complex interactive components (modals, dropdowns, tabs) because they provide correct ARIA patterns out of the box. We test with VoiceOver on macOS and NVDA on Windows and verify keyboard-only navigation for every interactive element.

Yes. Storybook is our standard tool for building and documenting component libraries. Every component is built with all documented Figma variants as Storybook stories, with props documentation, interaction tests, and accessibility annotations. The Storybook becomes a living reference for your entire engineering team.

We begin every engagement with a Figma file review. If the file has quality issues - missing states, inconsistent spacing, or ambiguous interactions - we flag them before development begins and work with your designer to resolve them. Building from an unclear spec is a leading cause of implementation rework.

Yes. We implement micro-interactions specified in the design file using Framer Motion for React-native animations and GSAP for scroll-triggered and timeline-based sequences. We match the designer's specified easing and duration values exactly and produce a side-by-side comparison video before sign-off.

Yes. We extend, refactor, and improve existing component libraries regularly. We audit the current library for accessibility issues, inconsistent prop APIs, and missing states, then deliver a prioritized improvement plan alongside any new components your design requires.

We measure Lighthouse performance scores before and after implementation. We optimize images (WebP/AVIF, lazy loading), eliminate render-blocking CSS, minimize JavaScript bundle size, use virtualization for long lists, and ensure animations run on the GPU compositor layer. Performance gates are part of our definition of done.

Yes. We write interaction tests in Storybook using the play function for user behavior coverage, visual regression tests via Chromatic to catch unintended visual changes, and Jest + React Testing Library unit tests for complex component logic. Test coverage requirements are agreed at project kickoff.

We test every component in Chrome, Safari, Firefox, and Edge at each required breakpoint. We use autoprefixer for CSS vendor prefixes, polyfill only where necessary (not by default), and document any known browser limitations with workarounds. Safari on iOS is tested on a physical device - not just an emulator.
