PROFILE
Jack Chan
Worked on the cardano-scaling/hydra repository to enhance backend reliability and efficiency in blockchain development. Focused on improving Blockfrost API integration by enabling genesis-based startup and optimizing API calls based on block time, which reduced unnecessary requests and improved data retrieval speed. Addressed code formatting issues in Haskell modules to align with project standards, resulting in a cleaner codebase. Additionally, maintained continuous integration stability by implementing a disk cleanup step in GitHub Actions using Bash and YAML, preventing build failures due to limited runner disk space. These efforts improved both system performance and the development feedback loop for hydra-node changes.

Jan 1, 2026January 2026: Maintained CI reliability for the cardano-scaling/hydra project by implementing a disk cleanup step in GitHub Actions to prevent space exhaustion during Nix derivation builds. This change, targeting limited runner disk space (~14GB), frees up critical headroom by removing large artifacts before builds and ensures successful compilation of hydra-node changes.
