Senior Frontend Developer (Next.js) & UI/UX designer

I build high-performance Next.js websites and applications that turn visitors into loyal customers, seamlessly blending expert frontend development with strategic, user-centered UI/UX design to deliver beautiful, intuitive interfaces that scale effortlessly and drive real business growth. As a frontend developer with many years of experience, I understand how interfaces are built, how components scale, how responsive systems behave, and how performance impacts user experience. This allows me to design with real implementation in mind and develop with full respect for the original design. As a result, my clients avoid common issues such as: designs created without considering long-term maintainability and scalability, inconsistencies between mockups and final development, slow, poorly structured frontend, misalignment between design and development. I ensure a smooth, structured process where design and development work together seamlessly. 💻 Frontend Development I convert Figma, Adobe XD, PSD, and Sketch designs into pixel-perfect, responsive, SEO-friendly, production-ready websites and web apps. Tech stack: HTML5, CSS3, SASS/SCSS JavaScript (ES6+) Next.js/React Tailwind CSS, Bootstrap AlpineJS Git I focus on clean architecture, reusable components, performance optimization, and cross-browser compatibility. 🎨 Developer-Minded UI/UX As a UI/UX Designer with strong frontend expertise, I create scalable, conversion-focused interfaces that are visually polished and technically feasible. Figma: Auto Layout, components, design systems, responsive layouts, interactive prototypes. Every design is built with performance, responsiveness, and real development constraints in mind. 🚀 Full-Cycle Delivery If needed, I provide complete website development: UI/UX Design → Frontend Development → WordPress Integration Including custom WordPress themes, ACF integration, flexible content structure, SEO, and speed optimization. You receive a fully functional, easy-to-manage website built with clean, scalable frontend architecture.
