UI/UX Implementation

Pixel-perfect implementation of your designs—Figma, Sketch, Adobe XD—with platform-native behaviors, smooth animations, and accessibility baked in. I bridge the gap between design and development, ensuring your vision translates seamlessly to production-quality screens.

Ideal for design-first teams who need a senior developer to implement their design system, or agencies looking for reliable implementation partners for client projects.

What I Implement

  • Design Systems: Component libraries, design tokens, theming
  • Platform-Native UX: iOS HIG, Material Design, gestures, haptics
  • Animations: Transitions, micro-interactions, Lottie, custom motion
  • Accessibility: VoiceOver/TalkBack, Dynamic Type, contrast, focus management
  • Responsive Design: Multiple screen sizes, orientations, safe areas
  • Localization: RTL support, dynamic text, locale-aware formatting

Deliverables

  • Production Screens: Fully functional, tested on target devices
  • Component Library: Reusable components with documentation
  • Design Tokens: Colors, typography, spacing, shadows as code
  • Motion Specs: Animation duration, easing, sequences
  • QA Checklists: Device testing matrix, accessibility audit
  • Handoff Notes: Implementation details for your team

Implementation Approach

1. Design Handoff Review

Review Figma/Sketch files, clarify ambiguities (e.g., missing states, edge cases), establish design QA process. Confirm font licenses, asset formats, motion specs.

2. Component Foundation

Build base components (buttons, text fields, cards) with design tokens (colors, fonts, spacing). Ensure reusability and consistency across screens.

3. Screen Implementation

Implement screens using component library, add platform-specific behaviors (e.g., iOS swipe-to-delete, pull-to-refresh), handle error states, loading states, empty states.

4. Animation & Polish

Add transitions, micro-interactions, haptic feedback. Test on real devices for smoothness. Profile with Instruments/Android Profiler to ensure 60fps.

5. Accessibility & QA

VoiceOver/TalkBack testing, Dynamic Type support, contrast ratios (WCAG AA), focus order. Device testing matrix (iPhone, iPad, Android phones/tablets).

Platform Expertise

iOS (SwiftUI & UIKit)

  • SwiftUI views with custom ViewModifiers
  • UIKit custom controls & animations
  • SF Symbols, Dynamic Type, Dark Mode
  • Haptic feedback, 3D Touch, Handoff
  • iOS HIG compliance (navigation, gestures)

Cross-Platform

  • Flutter widgets, custom painters, animations
  • React Native components, Reanimated
  • Platform-specific code (iOS/Android)
  • Gesture handlers, pan responders
  • Adaptive layouts for tablets

Typical Outcomes

  • Pixel-perfect screens matching design specs across devices
  • 60fps animations with smooth transitions and micro-interactions
  • WCAG AA accessibility for VoiceOver/TalkBack users
  • Reusable component library for faster future feature development
  • Design QA process for ongoing alignment between design and dev

Perfect For

  • Design-First Teams: Have beautiful designs but need senior dev to implement
  • Agencies: Looking for reliable implementation partner for client work
  • Redesigns: Updating legacy app UI to modern design standards
  • Design Systems: Building component library from scratch or migrating existing
  • Accessibility Compliance: Need WCAG AA/AAA implementation for VoiceOver/TalkBack

Frequently Asked Questions

Do you work with existing design systems?

Yes—I can implement designs from Figma, Sketch, Adobe XD, or any design tool. If you have an existing design system (Material Design, custom components), I'll follow your guidelines. If not, I can help establish one.

How do you ensure pixel-perfect implementation?

I use design handoff tools (Figma Inspect, Zeplin) for exact specs, test on multiple devices (iPhone 12-16, iPad, Android), use design QA checklists, and provide side-by-side comparison screenshots for review.

What about animations and micro-interactions?

I implement custom animations using platform-native APIs (UIView.animate, Core Animation for iOS; MotionLayout for Android; Animated API for React Native). Complex motion specs are prototyped and reviewed before final implementation.
