Andrew Hoskins engineered robust dependency management features for the gleam-lang/gleam repository, focusing on safer upgrades and improved developer experience. Over five months, he refactored the compiler’s dependency system in Rust, introducing a centralized DependencyManager and exposing public APIs to support external tooling. He enhanced major-version resolution, implemented user-facing notifications for breaking changes, and optimized performance through caching and modularization. Andrew also stabilized Git-based dependency handling, reducing CI flakiness and streamlining local development. His work emphasized maintainability, reliability, and clear documentation, demonstrating depth in API design, code refactoring, and compiler development while addressing real-world challenges in package management workflows.

March 2025: Delivered reliable Git-based dependency management for Gleam, resulting in improved stability and reproducibility of Git-based dependencies in the Gleam compiler. Refactored the Git dependency handling and updated internal build configurations to reduce instability during rebases, and performed post-rebase formatting cleanup to improve code quality. These changes reduce CI flakiness, streamline local development, and lay groundwork for smoother future updates to Git-based dependencies.

February 2025 (2025-02) — Key delivery: Gleam compiler dependency management refactor and public API exposure. Refactored dependency management by moving DependencyManager and related logic into a new submodule (dependency_manager.rs), improving modularity. Made DependencyManagerConfig public and re-exported it from the main dependencies module to enable external usage. This work reduces coupling, enhances testability, and lays groundwork for external tooling integration without changing external behavior.

January 2025: Delivered key dependency-management enhancements and internal refactor for gleam-lang/gleam. Implemented user-facing messaging improvements for major dependency version notifications, and completed a comprehensive Dependency Management System refactor to improve reliability, maintainability, and API cleanliness. Updated tests and documentation to reflect new APIs and behavior. The work reduced maintenance overhead and set the stage for safer upgrades and automated checks in downstream projects.

November 2024 (2024-11) summary for gleam-lang/gleam: Implemented direct-dependency–centric major-version resolution to improve upgrade safety and visibility of breaking changes. Introduced resolve_major_versions to identify latest stable major versions, surface new major versions for direct dependencies, and surface breaking-change awareness while ignoring transitive and pre-release versions. The change tightens the focus to direct-declared dependencies, applies stable-version filtering, and uses deterministic sorting to select the latest stable release. This work reduces upgrade risk for users and provides clearer signals for maintainers.
