Worked on the agda/agda repository over two months, focusing on both core language enhancements and repository maintenance. Developed an upgrade to Agda’s instance search, improving how eta-record-producing functions resolve instance fields, particularly under visible telescopes. This involved generalizing instance-argument handling, refining implicit argument processing, and updating documentation and tests to ensure reliability for developers working with type theory and functional programming in Haskell. Additionally, contributed to repository hygiene by updating the .gitignore to exclude .mjs test artifacts, streamlining version control and reducing build noise. Demonstrated skills in Agda, Haskell, repository management, and version control throughout the work.
May 2026 (agda/agda): Focused on repository hygiene to reduce noise and improve maintainability. Key feature delivered: Updated .gitignore to exclude .mjs test artifact files, ensuring test artifacts aren’t tracked in version control. Commit: faa9327330b9e1c1761c0fdf8d0a37a0b1bd42fa. Major bugs fixed: none reported this month for this repo. Overall impact: Cleaner repo, reduced CI/build noise, faster onboarding for new contributors, and clearer history for code changes. Technologies/skills demonstrated: Git hygiene, ignore-file patterns, lightweight change management, attention to artifact leakage control.

January 2026: Focused on strengthening Agda's instance search for eta-record-producing functions. Delivered a partial fix for issue #8337, enhancing implicit argument handling, generalizing instance-argument processing, and ensuring instance fields are correctly resolved under visible telescopes. This work included documentation updates, changelog entry, and targeted tests to validate the upgraded search behavior. The changes improve reliability for developers upgrading instance fields and reduce time spent on debugging around eta-expansion.
