Modern Pokédex

A modern, stylish, and interactive Pokédex application built with Next.js and TypeScript, meticulously designed to be as visually appealing as it is functional. This project demonstrates a passion for creating beautiful user interfaces with a focus on performance and smooth animations. It goes beyond a typical Pokédex by presenting exclusive data and insights about each Pokémon, offering information not available on other platforms, including the official Pokédex. Users can browse and search a vast collection of Pokémon, view detailed statistics, and explore their evolutionary chains. The application leverages the PokéAPI for data and is built with a fully responsive design for a seamless experience on any device.
