PROFILE
Jack Chan
Andrew Jackson contributed to the cardano-scaling/hydra repository by enhancing backend reliability and efficiency through targeted improvements in API integration and DevOps workflows. He developed a genesis-based startup feature for Blockfrost integration using Haskell, optimizing API calls based on block time to reduce unnecessary requests and improve data retrieval speed. Andrew also addressed code formatting issues in Blockfrost.hs, aligning the codebase with project standards. In addition, he stabilized continuous integration pipelines by implementing disk cleanup steps in GitHub Actions with Bash and YAML, preventing build failures due to limited runner space. His work demonstrated depth in functional programming and CI automation.

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.
