QA Engineer at Visma testing a bank integration service and creating reusable AI skills for test-data generation.

At Visma, I test a bank integration service that automates payment flows between accounting systems and banks. I work across front-end and back-end components, using Claude and GitHub Copilot to generate and extend automated tests.

I also create reusable AI skills for test-data generation and standardized test creation. This work has reduced test creation time by approximately 30%.

At Endava, I led a four-member QA team testing a web application for car dealers. I owned test planning, strategy, and execution, and identified opportunities for test automation.

Earlier, I tested digital payments at Endava, telecom software at Nokia, and automotive infotainment systems at Continental Automotive. I’ve worked across manual and automated testing, including end-to-end and regression testing.
