Problem

A developer portfolio that just lists technologies convinces no one — clients want proof you can ship a real production system, not a slide deck of buzzwords.

The Challenge

Build a portfolio that is itself a product — demonstrating full-stack capabilities including AI integration, CMS, auth, and automated deployment in one codebase.

The Solution

Next.js 15 App Router + React 19, Prisma + PostgreSQL, Sanity CMS, Gemini AI chatbot via Vercel AI SDK, NextAuth v4 GitHub OAuth, Upstash Redis rate limiting, GitHub Actions CI/CD, Framer Motion animations.

Technical Highlights

Server Components with selective client islands (Next.js 15 App Router)

Gemini AI chatbot via the Vercel AI SDK with streaming responses

Dual content sources: Sanity CMS + PostgreSQL/Prisma with a static fallback

NextAuth v4 GitHub OAuth with a role-based admin dashboard

Upstash Redis rate limiting on every API route

GitHub Actions CI — typecheck, tests and build on every push
