Worked on enhancing UI test reliability for AI chat height calculations in the duckduckgo/apple-browsers repository. Focused on refactoring UI test assertions using Swift and unit testing techniques to ensure accurate height measurements within the AI chat interface. Addressed and resolved merge conflicts in the feature branch, which contributed to stabilizing the continuous integration process and enabled smoother code integration. The improvements led to reduced test flakiness, providing faster feedback cycles and more predictable release timelines for the AI chat UI on Apple browsers. Demonstrated a methodical approach to iOS development, emphasizing test accuracy and CI stability throughout the project.
