Worked on the mendableai/firecrawl repository to stabilize automated Playwright testing within Docker containers. Addressed a persistent startup issue by relocating the Chromium browser path in the Dockerfile, ensuring Chromium was correctly installed and discoverable during container initialization. This fix resolved failures caused by missing Chromium under /tmp/.cache, particularly affecting Docker 4.46 environments, and led to more reliable Playwright service startups. The solution improved continuous integration reliability and reduced test flakiness, directly supporting deployment confidence. Demonstrated proficiency in containerization, DevOps, and Dockerfile management, while collaborating cross-functionally to deliver a maintainable fix for Playwright and TypeScript-based test infrastructure.
