You've been burned by "pixel-perfect" before. Here's what that actually looks like in React. You already have the design. What you need is a Front end Developer who reads a Figma file like a spec, not like a mood board - and delivers React and Next.js components that your team can actually maintain six months later. No "almost done", no mystery CSS, no excuses on mobile. That's what I build. I work with React, Next.js, TypeScript, and Tailwind CSS - and I know exactly where most implementations go wrong. ⚡ What you get ◆ Figma → React / HTML / CSS - your design, implemented exactly. Responsive by default, accessible markup, components your team can reuse without reverse-engineering. ◆ React & Next.js apps - SaaS platforms, dashboards, eCommerce UIs with SSR/SSG, TypeScript, Redux, and REST API integration. Architected to scale, not just to demo. ◆ Landing pages that load fast and convert - built with Next.js and Tailwind CSS, Lighthouse 90+, Core Web Vitals stable. Because a slow page is a lost lead. ◆ Performance optimization - faster TTFB, stable Core Web Vitals, SEO-friendly Next.js architecture. The kind of score your marketing team can actually show to stakeholders. ◆ Animations & interactions - smooth UI motion with Framer Motion and GSAP, from micro-interactions to full page transitions. Fast, not flashy for the sake of it. 🏆 Why clients choose me ✓ Top Rated on Upwork - 100% Job Success Score across 150+ projects ✓ 7+ years in frontend development - I've seen what breaks in production and I build around it ✓ AI-assisted workflow - faster delivery without cutting corners on quality ✓ Code that's clean, documented, and easy to hand off - your next developer will thank you ✓ Mobile-first by default, no exceptions ✓ You'll always know what's done, what's next, and why - no chasing for updates 🛠 Tech stack React.js · Next.js · TypeScript · JavaScript (ES6+) · HTML5 · CSS3 / SCSS · Tailwind CSS · Styled Components · Redux Toolkit · React Query · Framer Motion · GSAP · REST API · Vite · Webpack · Git · GitHub · Vercel · Netlify · Cloudflare · Node.js 📩 Tell me what you're building - share a Figma link, a brief, or just a few sentences about the problem.
