CertifyCrafter
A full SaaS platform for bulk certificate and ID generation — built and shipped end to end. Used by teachers, HR teams, and event organizers to produce hundreds of personalized, verifiable documents in minutes.
01 · THE CHALLENGE
Organizations generating certificates at scale were stuck with manual design tools — copy-pasting names into templates one by one, with no way to verify authenticity afterward. Slow, error-prone, and impossible to audit.
02 · KEY DECISIONS
Template editor over rigid presets — flexibility without design skills. QR-based verification baked in from day one for trust. Credit-based billing to match sporadic, bursty usage.
03 · ARCHITECTURE
Next.js front end with a Firebase backend for auth, storage, and real-time data. Server-side batch generation for performance at volume, Paddle for billing and tax handling, and QR verification endpoints for credential checks.
04 · WHAT I'D DO DIFFERENTLY
I'd invest in the batch-rendering pipeline earlier. It became the core value once teams started generating hundreds at a time — building for that scale from the start would have saved a refactor.
