Built and deployed a full-stack AI content platform that generates, humanizes, paraphrases, and detects AI-written text using Google's Gemini API. Architected as a Next.js 16 monorepo with a credit-based usage system, Google OAuth authentication (NextAuth), and Stripe-powered subscription billing. Migrated the backend from a standalone Express/Node.js server to Next.js App Router serverless API routes, enabling a fully unified deployment on Vercel. Used Prisma ORM with a pooled PostgreSQL database (Supabase) for serverless-safe data access, and implemented secure JWT-based session handling, credit deduction logic, and Stripe webhook event processing for plan upgrades. Tech stack: Next.js, TypeScript, React, Prisma, PostgreSQL, NextAuth.js, Stripe, Google Gemini API, Vercel.
