# Juwon Daniel > Toptal vetted Frontend Developer & UI/UX Designer | React, Next.js, Typescript, TailwindCSS | Full-Stack | Building Beautiful, Scalable Web Applications Location: Lagos, Lagos State, Nigeria Profile: https://flows.cv/juwondaniel I'm a Frontend Developer and UI/UX Designer with over 5 years of experience building beautiful, responsive web applications that users love. I specialize in turning ideas into pixel-perfect, production-ready products and I handle both the design and the code. WHAT MAKES ME DIFFERENT Most developers can't design. Most designers can't code. I do both. As a Frontend Engineer, I build fast, scalable interfaces with React and Next.js. As a UI/UX Designer, I craft intuitive user experiences that look great and feel effortless. And when needed, I can handle full-stack development to ship complete features end-to-end. This design + development combo means: → Faster delivery (no designer-developer handoff friction) → Better user experience (I code with UX in mind) → Pixel-perfect implementation (what you see in Figma is what you get in production) → Full ownership (I can design, build, and deploy complete features) MY CORE SKILLS Frontend Development: React, Next.js, TypeScript, Tailwind CSS, ShadCN UI, Responsive Design, Mobile-First Development UI/UX Design: Figma, User Research, Information Architecture, Wireframing, Prototyping, Design Systems, High-Fidelity Mockups Full Stack (when needed): Node.js, Express, Supabase, Firebase, REST APIs, Authentication, Database Design IDEAL PROJECTS I'm best suited for projects where design quality and frontend excellence matter: - Startups building their first product (MVP to launch) - Redesigns that need both UI/UX and frontend work - Products where user experience is a competitive advantage - Teams that need someone who can design AND code If you're building something ambitious and need a Frontend Developer who can design, code, and ship, let's connect. ## Work Experience ### Full Stack Engineer & UI/UX Designer @ Capsured - capsured.com @ Squarelabs Jan 2024 – Present - Designed and developed a comprehensive luxury car CRM and ERP platform that helps high-end automotive businesses manage their operations.
