Worked on the browser-use/web-ui repository to address stability and reliability issues in the Docker-based CI/CD pipeline. Focused on resolving a critical Docker build problem by removing an unnecessary dependency, which improved build consistency and reduced failures. Enhanced the test environment by adding essential font packages, leading to better character rendering during automated tests. Updated the Playwright installation process to ensure Chromium was reliably installed, minimizing test flakiness. Simplified and aligned the docker-compose.yml configuration for consistency across environments. Utilized Dockerfile and YAML extensively, applying CI/CD best practices to deliver targeted improvements without introducing new features during the project period.
