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.
