EarnDLT (GreenTruth) (https://earndlt.com) is a blockchain-based carbon compliance platform that helps companies track and report emissions data under the EU's Carbon Border Adjustment Mechanism (CBAM) and Scope 3 supply-chain requirements. The backend was live and running on NestJS with a GraphQL API, but as the platform scaled, it needed to support third-party data providers who expected standard REST endpoints rather than a GraphQL schema. πŸš€ What I worked on As part of the engineering team, I worked on migrating the core backend from GraphQL to a REST API architecture, on a platform already handling live compliance data. This involved mapping existing GraphQL queries and mutations to equivalent REST endpoints and reworking the data-access and request/response contracts so external providers could integrate cleanly. πŸš€ Stack: NestJS for the backend framework TypeScript across the API surface PostgreSQL for compliance and emissions data Next.js on the frontend REST replacing GraphQL as the integration layer πŸš€ The key challenge The migration ran over 1-2 months on a live platform handling real regulatory data, so downtime and inconsistency weren't options. The team took an incremental approach β€” standing up REST endpoints alongside the existing GraphQL layer, validating parity, then cutting over integrations gradually rather than in one hard switch. πŸš€ What shipped A production REST API layer that opened EarnDLT up to third-party emissions-data providers, with no disruption to the platform's live CBAM/Scope 3 compliance reporting.
