Worked on the LedgerHQ/ledger-live repository to improve test hygiene for the ZCash shielded path by delivering a targeted logging cleanup in the test suite. The approach involved removing console.log statements from error handling within TypeScript-based tests, which reduced unnecessary log noise and enhanced the readability of test outputs. This change aligned with continuous integration goals by enabling faster diagnosis and triage of test failures. The work demonstrated effective use of automation tools, with Copilot co-authoring the refactor, and showcased a focus on maintainable testing practices. Skills applied included TypeScript and testing, emphasizing clean, efficient, and reliable test environments.
