Rockstar🎓
Top SchoolErwin Heitzman is a Senior Test Automation Engineer with a decade of experience building robust, maintainable test platforms for web and component ecosystems. Based in the Netherlands, he has driven modern WebdriverIO-based setups at Rabobank that cover accessibility, visual regression, styles and functional tests while prioritizing ease of use, speed and stability. An active contributor to the popular webdriverio project, he implemented and hardened cookie commands and edge-case test coverage, showing attention to detail in core automation tooling.

Colleagues know him for learning new domains quickly (CSS and web components at scale) and turning that curiosity into practical, cross-team improvements.
