WebtoonLike is a complete redesign of a webtoon reading platform. I led the analysis, design, and redevelopment of the site to improve performance, security, and user experience. The project included migrating to Next.js for optimized server-side rendering and better SEO, as well as restructuring the database to MongoDB for more efficient content management. I also developed a responsive interface, a user management system with roles and permissions, and advanced search and filtering features. The deployment was accompanied by load and security testing to ensure robustness and scalability.
