In this course, I will guide you step by step through the process of building a complete, modern, and professional portfolio website using Next.js 14, React.js, Tailwind CSS, and Nodemailer. Based on my experience helping students understand complex front-end concepts, I focus on clear explanations, real-world examples, and practical implementation. Instead of just explaining theory, we build everything together—from project setup to final deployment—so you fully understand why and how things work. You will learn the core concepts of Next.js 14, including the App Router, file colocation, private and dynamic routes, navigation, layouts, metadata, and loading states. Once the fundamentals are clear, we will build a full portfolio website with dynamic content, smooth scrolling animations, downloadable PDF files, and call-to-action buttons driven by scroll state. By the end of the course, you will deploy your website on Vercel, publish the source code on GitHub, and confidently understand the difference between React routing and Next.js routing, while knowing how to build real-world, production-ready applications. No prior experience with Next.js is required.

We minimize complex configurations and difficult theories, and focus on getting a hands-on feel for web development flow by writing code that actually works. This course centers on 'hands-on experience' rather than just 'learning.' If you've touched code even a little bit, anyone can follow along and feel the satisfaction of completion.
