PROFILE
Iris Garcia
Iris Garcia de Sebastian contributed to the zenrocklabs/zrchain repository, focusing on blockchain infrastructure and reliability. Over seven months, she engineered features such as Regnet network support for Bitcoin and Solana, robust end-to-end testing for cross-chain minting, and enhancements to transaction fee handling. Her technical approach combined Go and Python development with Docker-based CI/CD pipelines, integrating protocol buffers and gRPC for network communication. Iris addressed complex issues like nonce flow stability, double-signature validation, and MPC timeout handling, ensuring data integrity and secure key management. Her work demonstrated depth in backend development, blockchain integration, and automated testing for production-grade systems.
