Diamond Certification & Verification Platform

GIL was a freelance project I built for a gemological institute. They needed a system where customers could verify diamond certificates online by entering a reference number, browse a gemstone encyclopedia, and learn about their grading process.
I built the whole thing from scratch — a public-facing site with 3D gem visualizations, a certificate verification system backed by PostgreSQL, and a secure admin dashboard for uploading and managing certificates. It was my first real client project, and shipping something that an actual business relies on taught me more about production engineering than any tutorial could.
Customers enter their certificate number and instantly get verification results pulled from the database
Detailed entries on 200+ gemstone varieties with properties, origins, and care information
Interactive 3D gem models and breakdowns of GIA-standard grading criteria
Protected admin panel for uploading certificates, managing records, and bulk operations
