Worked on the LedgerHQ/app-exchange repository to streamline the Exchange app’s test suite by removing Sui swap tests, focusing on improving the efficiency and maintainability of backend testing workflows. Used Python to refactor the test suite, reducing the overall test surface area and thereby decreasing continuous integration run times. This change enhanced the reliability of developer feedback loops and contributed to faster release cycles. The approach emphasized code hygiene and collaborative development through a pull request-driven workflow. The work demonstrated a strong grasp of backend development and testing practices, delivering a targeted solution that optimized the project’s ongoing maintenance requirements.
