Guillaume Cisco is a Senior Software Engineer based in Paris with 14 years of experience building scalable full‑stack systems, blockchain platforms, and developer tooling. He blends backend expertise in Python/Django and Hyperledger Fabric with front‑end skills in React, Node.js and PWA/SSR optimizations, having shipped production services and internal data‑analysis tools for healthcare and consumer products. At Owkin he led a team building a privacy-preserving blockchain ecosystem for medical research and contributed core identity and CA features to the Fabric Python SDK; at Forest Admin and open-source projects he improved database model generation and fixed real SSR/styling issues in popular React spinner components. Comfortable with cloud-native deployments (Kubernetes, GCP/AWS), CI/CD and advanced cryptography, he pairs system design with hands‑on implementation and test-driven delivery. Colleagues describe him as a pragmatic engineer who surfaces subtle edge cases—like CORS/JSON parsing and prop-update bugs—and turns them into durable fixes.

Contributions summary:Guillaume implemented and added tests for the Fabric-ca register method, enabling user registration within the Hyperledger Fabric Python SDK. They then added a CA Revoke method, enabling certificate revocation within the Fabric CA service. The user also implemented affiliation management methods, including create, get, update, and delete operations, and also implemented methods for re-enrollment and generation of CRLs. These changes enhanced the SDK's functionality for identity and certificate management within a blockchain environment.

Contributions summary:Guillaume primarily contributed to the backend of the `lumber` project, focusing on features related to database model analysis and generation. Their work involved refactoring code for model relationships, particularly `belongsToMany` associations. They also addressed a CORS middleware issue to resolve JSON parsing problems and fixed a bug related to handling column names containing parentheses in the database models. Furthermore, they added new test cases demonstrating the fixes.
