Blockchain Digital Certificate Platform
Enterprise-grade digital certificate issuance and verification system built on AWS Managed Blockchain with Hyperledger Fabric. Ensures tamper-proof credential verification for educational institutions and certification bodies.
The Challenge
Educational institutions and certification bodies issue credentials that are trivially easy to forge and slow to verify. Employers and regulators need a way to confirm a certificate is genuine without trusting the issuer's database, and issuers need a platform that can serve many organisations securely at once.
What We Built
We architected and led a multi-tenant SaaS platform end to end, built on a modern Node.js/TypeScript stack (Apollo GraphQL, TypeORM, PostgreSQL) with a customer-facing product in Next.js. A Hyperledger Fabric blockchain layer makes certificates tamper-evident and verifiable, with a public verification explorer anyone can use. Multi-tenant onboarding runs on Cognito authentication with Stripe billing, and the AWS infrastructure and CI/CD is fully Terraform-managed with self-hosted GitHub Actions runners and shared reusable workflows.
The Outcome
The platform has issued more than 50,000 tamper-proof certificates with 100% verifiable authenticity and 99.9% uptime, serving multiple issuing organisations on shared, isolated infrastructure.
