Worked on the onekey-sec/unblob repository to enhance both reliability and developer experience within a Nix-based workflow. Addressed extraction stability issues by downgrading the 7zip dependency in Nix packaging to version 16.02, aligning with Debian and resolving behavioral inconsistencies affecting MBR partitions and ZIP handling. Improved the development process by updating direnv to monitor all .nix files, enabling automatic environment reloads for smoother iteration. Introduced pre-commit hooks for Nix linting and formatting, raising code quality and consistency. Leveraged skills in CI/CD, DevOps, and dependency management, with a technical focus on Nix and Shell scripting throughout the project.
