Software Test Team Lead at Mizaic, leading NHS QA and maintaining a Cypress and Playwright automation framework.

United Kingdom

Message

At Mizaic (IMMJ Systems), I own the test strategy for a healthcare platform that helps NHS hospitals scan, index and archive paper medical records. I lead three QA Engineers across Agile squads and designed and maintain a Cypress, Playwright and TypeScript/JavaScript automation framework for critical workflows, UI components and APIs.

I introduced AI-assisted testing with Cursor AI and Model Context Protocol, and integrated automated suites into CI/CD pipelines. My work has increased test coverage, reduced manual regression effort and contributed to reducing customer-reported incident tickets by up to 50%; earlier at GFM, I tested fantasy sports and holiday-booking products and led a team of six testers.
