Mira Calder
Partner, Quality Engineering
A release you can defend, not a ritual you survive.
Mira holds quality engineering at Runtime Studio London. Teams ask for her when shipping has become a performance: a week of clicking, a known list of flakes, a QA group that cannot reach the risks that actually move money or trust.
She maps the critical path, chooses a stack the team already speaks — usually Playwright and TypeScript — and leaves a suite they will still run in six months. On an engagement she still writes the first tests herself.
Qualifications
- Former Head of Quality, card-issuing platform
- Playwright and TypeScript on the money path
- Release gates in GitHub Actions and GitLab CI
Works on
- Test architecture for teams past their first automation attempt
- Critical-path suites internal QA can own
- Release gates that stop a bad build without stopping the week
