Convert Figma Design to Website with Animations
Fayaz did an excellent job converting our Figma design into a website. However, it's worth noting that he works part-time. Despite this, his technical skills and attention to detail were top-notch, resulting in a visually appealing final product. Clarifying availability expectations upfront would further enhance the experience of working with him.

I build fast, production-ready web apps with Next.js, React, and Supabase — whether that's a SaaS dashboard, a client portal, an e-commerce storefront, or an AI-powered tool. If it runs in a browser and needs to scale, I can build it.
I don't just implement UI. I architect frontend systems with clean structure, optimized performance, and code that your team can maintain and build on long-term.
