Hire a UI/UX Developer.
Pixel-perfect. Accessible. Fast.
Looking to hire a UI/UX developer or front end web developer? I'm Aleksandar Kuzmanovic — a frontend engineer who builds pixel-perfect, responsive, and accessible user interfaces with React, Next.js, TypeScript, and TailwindCSS. I bridge the gap between design and engineering.
I don't just implement designs — I optimise them for performance, accessibility, and search engines. Every interface I build is responsive across all devices, accessible to all users (WCAG compliant), and loads in under 1 second. I design in Figma and implement in code, ensuring the final product matches the vision perfectly.
From custom design systems and component libraries to complex data visualisation dashboards and animated landing pages — I handle the full UI/UX development lifecycle. My frontends are built with TailwindCSS for maintainable styling, Framer Motion for fluid animations, and semantic HTML for accessibility and SEO.

Services & deliverables.
End-to-end.
Figma-to-Code Implementation
Pixel-perfect translation of Figma, Sketch, or Adobe XD designs into production React components with TailwindCSS. Every detail implemented exactly as designed.
Responsive Frontend Development
Mobile-first, fully responsive interfaces that adapt across all screen sizes. Fluid typography, responsive images, and flexible layouts with proper breakpoint handling.
Component Library & Design Systems
Reusable, documented React component libraries with consistent styling, TypeScript types, and Storybook integration. Design systems that scale with your product.
Accessible Interface Development
WCAG-compliant interfaces with semantic HTML, ARIA attributes, keyboard navigation, focus management, and screen reader testing. Inclusive design that reaches all users.
Interactive Animations & Transitions
Purposeful animations with Framer Motion — page transitions, micro-interactions, scroll-triggered effects, and loading states that enhance UX without impacting performance.
Frontend Performance Optimisation
Core Web Vitals optimisation, code splitting, lazy loading, bundle analysis, and rendering performance tuning. Beautiful interfaces that also load instantly.
Why hire me as your UI/UX developer?
Figma-to-Code Precision
I translate Figma designs into pixel-perfect React components. Every spacing, colour, and typography detail is implemented exactly as designed — with clean, maintainable code underneath.
Responsive & Mobile-First
Every interface is built mobile-first and adapts seamlessly across all screen sizes. Fluid typography, responsive grids, and touch-optimised interactions that work on every device.
Accessibility by Default
Semantic HTML, ARIA labels, keyboard navigation, focus management, screen reader compatibility, and colour contrast compliance. Accessible interfaces are better for everyone — and they rank higher.
Performance-Optimised UI
Code splitting, lazy loading, optimised image formats (AVIF/WebP), efficient re-renders, and minimal bundle sizes. Beautiful interfaces that load in under 1 second.
Animation & Micro-Interactions
Smooth, purposeful animations with Framer Motion and CSS transitions. Loading states, hover effects, page transitions, and scroll-triggered animations that enhance UX without hurting performance.
Design System Development
Reusable component libraries with consistent typography, colour systems, spacing scales, and interactive patterns. Design systems that scale across your application and keep your team productive.
My process.
Simple. Transparent.
Design Review & Planning
Analysis of your designs (or creation of new ones in Figma). Component inventory, responsive breakpoint planning, accessibility requirements, and animation specification.
Component Architecture
React component hierarchy, state management strategy, styling approach with TailwindCSS, and TypeScript type definitions. Clean architecture before coding begins.
Pixel-Perfect Development
Component-driven implementation in React/Next.js. Mobile-first responsive styles, accessibility attributes, and semantic HTML. Regular visual QA against designs.
Animation & Interaction
Micro-interactions, transitions, hover states, loading patterns, and scroll effects with Framer Motion. Purposeful motion that guides users and enhances the experience.
Testing & Optimisation
Cross-browser testing, responsive testing, accessibility audit, Lighthouse performance scoring, and bundle size optimisation. Launch-ready frontend quality.
Technology Stack
The art of frontend engineering.
Great UI/UX development is invisible — users don't notice the perfect spacing, the accessibility, or the sub-second load time. They simply experience a website that feels right. This invisible quality is the result of disciplined engineering: semantic HTML for structure, CSS for presentation, JavaScript for interactivity, and careful attention to performance at every step.
The gap between design and development is where most projects lose quality. A designer creates a beautiful Figma mockup, but the developer implements it with incorrect spacing, wrong fonts, or missing responsive behaviour. Aleksandar eliminates this gap by doing both: he designs in Figma and implements in React, ensuring pixel-perfect fidelity while writing clean, maintainable code.
Accessibility is not an optional feature — it is a requirement for professional web development. Over 1 billion people worldwide have some form of disability. Accessible websites reach more users, perform better in search engines, and often qualify for legal compliance requirements. Aleksandar builds accessibility into the foundation: semantic HTML, ARIA attributes, keyboard navigation, focus management, and colour contrast compliance.
TailwindCSS has transformed frontend development by replacing custom CSS with a utility-first approach that keeps styles consistent, maintainable, and performant. Combined with React's component model and TypeScript's type safety, it enables rapid development without sacrificing quality. Aleksandar's component libraries are reusable, well-typed, and production-ready.
Performance is a core UX metric, not a technical afterthought. A beautiful interface that takes 5 seconds to load provides a worse user experience than a simple one that loads instantly. Aleksandar engineers performance into every frontend project: code splitting, lazy loading, optimised images, efficient re-renders, and minimal JavaScript bundles. The result is interfaces that look stunning and feel instant.
Common questions.
Clear answers.
- What does a UI/UX developer do?
- Translates designs into pixel-perfect, responsive, accessible code. Focus on user experience — smooth interactions, fast loads, intuitive navigation, and accessible interfaces across all devices.
- What is the difference between a UI/UX designer and developer?
- A designer creates visual mockups in Figma. A developer writes the code that makes them real. Aleksandar does both — designs and implements with React, Next.js, and TailwindCSS.
- Why is frontend performance important for UX?
- Users expect pages to load in under 2 seconds. Slow interfaces increase bounce rates. Aleksandar engineers sub-1s frontends — beautiful design with performance that converts.
- Do you work with existing design systems?
- Yes. Aleksandar can implement designs from Figma, Sketch, or Adobe XD, work within existing design systems, or create new component libraries from scratch with TailwindCSS and TypeScript.
- Can you do both design and development?
- Yes. Aleksandar designs in Figma and implements in React/Next.js. This eliminates the gap between design and development — no pixel drift, no feature misinterpretation, and faster iteration cycles.
- What is WCAG accessibility compliance?
- WCAG (Web Content Accessibility Guidelines) ensures websites are usable by people with disabilities. This includes screen reader support, keyboard navigation, colour contrast, focus management, and semantic HTML. Accessible websites also rank better in search engines.
- Do you build responsive websites?
- Every website Aleksandar builds is fully responsive. Mobile-first development with fluid typography, responsive images, flexible layouts, and touch-optimised interactions. Seamless experience from mobile phones to ultra-wide desktop monitors.
