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. Our client also had a legacy .NET signature platform that was slowing delivery; the credential system needed modern foundations, not just a blockchain bolted on.
What We Built
We architected and led a multi-tenant SaaS platform end to end. The legacy .NET API was migrated to 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, while the .NET-to-TypeScript migration improved maintainability and delivery speed for every release since.
This project was delivered by our blockchain development practice.
