UI/UX Designer & React Developer | Next.js, TypeScript, Figma to Code
93% Job Success
4.9  (12 reviews)
Rawalpindi, Pakistan - 1:16 am local time
UI/UX Designer and React Developer building Next.js applications with TypeScript - Figma to production code in one person. Initial bundle 85KB gzipped (your app loads instantly), TTI under 1.2 seconds on 3G (fast on slow networks), zero layout shift on hydration (no jumping elements). AI responses streaming token-by-token (users see output generating in real-time).

I design the interface in Figma and build it in React. Same person.
What this solves is "Handoff Friction" when a designer creates the interface and hands it to a developer, the final product loses 40% of what made the design work. Spacing drifts. Interactions disappear. The prototype felt instant, the production app feels sluggish.

That gap doesn't exist when one person owns both.

WHAT I BUILD

SaaS Product Interfaces: Figma prototypes with every interaction state mapped, then pixel-perfect React and Next.js implementation. Design systems with 200+ reusable components where new features ship in 2-3 days because most of the UI assembles from existing primitives.

AI-Integrated Products: OpenAI and Claude API integration with streaming responses (users see AI output generating in real-time). RAG pipelines with semantic search and conversation memory. AI orchestration server-side, frontend presents it cleanly.

Enterprise Dashboards: Interfaces handling 100,000-row datasets without slowing down. Real-time WebSocket streams with optimistic updates. Server-side filtering and pagination. Role-based access control.

Product Redesigns : Codebases with "Interface Drift" where there are 30 button variants, scattered state management, no clear patterns. I audit with React DevTools Profiler, rebuild with proper component architecture. Products can grow again.

WHY MY INTERFACES LAST

Design System Architecture:Design tokens synced between Figma and code. TypeScript for self-documenting APIs. Storybook with visual regression testing. New developers ship features in 3 days, not 3 weeks.

Performance Engineering: Bundle under 100KB. React Server Components for data, Client Components for interaction. Core Web Vitals passing on production, not just localhost.

Built for AI Integration: Architecture structured so adding AI features is a new component, not a refactor. Streaming handlers in place. Context management established.

Stack: React · Next.js 14 · TypeScript · Tailwind CSS · Framer Motion · Shadcn UI · Node.js · PostgreSQL · OpenAI API · Claude API · Figma · Vercel

BEng + BCS · IBM Design Thinking certified · 15+ years shipping SaaS platforms, FinTech, healthcare, eCommerce

Currently building with AI-assisted tools including Cursor and Claude Code.
