I'm Karol Piotrowski, a Senior Software Quality Engineer / SDET with a strong background in manual and automated testing, CI/CD integration, infrastructure debugging, and QA process leadership. I excel at Agile/Scrum collaboration, requirements analysis, and mentoring teams toward higher testing maturity. I balance hands-on automation delivery with test strategy and continuous improvement across SDLC and STLC, while actively exploring AI-powered tools and Playwright community-driven best practices. I'm passionate about shaping test architectures, driving testing strategies across teams, and guiding cross-functional work between Development and Business. I regularly experiment with AI-assisted tools like GitHub Copilot, Claude 4.5, and Playwright MCP within VS Code to streamline framework implementation, documentation, and maintenance. I use projects like Playwright-based frameworks as sandboxes for PoCs and training new joiners.
