Building a Modern Portfolio with Next.js 15 and Supabase
A comprehensive guide to building a professional developer portfolio using Next.js 15 App Router, Supabase for the backend, and Tailwind CSS for styling.
Why Build Your Own Portfolio?
As developers, our portfolio is our digital handshake. It's the first thing potential employers and clients see. While template-based portfolios are quick, building your own showcases your skills in the most authentic way possible.
Tech Stack Overview
Next.js 15 — App Router with React Server Components for optimal performance
Supabase — PostgreSQL database with real-time subscriptions and auth
Tailwind CSS 4 — Utility-first styling with a custom dark theme
Framer Motion — Smooth scroll-triggered animations
Setting Up the Project
Start by creating a new Next.js project with TypeScript and Tailwind CSS:
npx create-next-app@latest my-portfolio --typescript --tailwind --app
cd my-portfolio
npm install @supabase/supabase-js framer-motionKey Architecture Decisions
The most important decision is using Server Components by default and only opting into client components when interactivity is needed. This gives us the best of both worlds: fast initial loads with dynamic features where needed.
Pro tip: Keep your data fetching in Server Components and pass serializable props to Client Components. Remember that functions (like icon components) can't cross the RSC boundary.
Conclusion
Building your own portfolio is a rewarding investment. It demonstrates your skills, gives you a platform to share knowledge, and creates a lasting digital presence. Start with the basics and iterate — your portfolio should grow with you.
