Description

Are your sprints generating too many late-stage bugs? I help product teams fix that by embedding quality early — before development starts, not after.

With 10+ years of QA experience across Dutch organisations including PostNL and Coolblue Energy, I bring a strategic approach to testing that goes beyond running test scripts. I work closely with product owners, developers, and analysts to make sure requirements are clear, testable, and agreed upon before a line of code is written. At PostNL, this approach reduced sprint bugs by 40–50%.

What I typically deliver for clients:

→ Test strategy and approach tailored to your team and product

→ API test coverage using Postman, REST, GraphQL

→ Automated test coverage using Cypress, Selenium, Karate or Playwright

→ End-to-end test execution, regression management and release sign-off

→ X-Ray and JIRA test management setup and rollout

I integrate quickly into existing Agile teams and work independently from day one. ISTQB certified. Based in North Holland — available on-site in Amsterdam, Utrecht and surroundings, hybrid, or fully remote.

Currently available for short and long-term contracts.
