About

Developer Experience Engineer at Ecosia. I work on CI/CD, internal tooling, and the workflows teams use to build and ship web and mobile products for millions of people.

Before this I owned acceptance-test automation and quality engineering across Android, iOS, web, Windows, and macOS. That work is what I use now: shorter build and test cycles, testing standards, and automation that keeps a release reliable.

I use AI-assisted engineering, including GitHub Copilot, Cursor, and Claude, where it improves the workflow.
