The Problem

Self-taught developers watch hundreds of hours of tutorials on YouTube but have no "proof" of their learning compared to paid platforms like Udemy or Coursera.

The Solution

CertifYT bridges this gap by using the YouTube Data API to fetch playlist details, calculate the total learning hours, and generate a professional PDF certificate with a verifiable QR code.

Technical Highlights

  • Next.js App Router: For fast server-side rendering of certificate pages.
  • Supabase: Storing user generation limits and certificate validation records.
  • Puppeteer (planned): To automate high-quality PDF generation server-side.
