What I'm looking for

I’m seeking to contribute as a student QA.

At Hello Heart, I designed a custom Claude workflow with the QA team that reduced regression test case preparation time by 50%. I validated generated cases for accuracy and coverage before execution.

I approved releases for blood pressure monitoring apps across iOS, Android, and web through regression and exploratory testing. I also checked health data synchronization and UI behavior for Apple Health and Google Fit integrations.

Previously, I led QA at Corsight AI for AI-powered facial recognition software, validating performance across web, mobile, and desktop. I’m currently studying for a B.Sc. in Life Sciences, Biotechnology track, at Open University of Israel and seeking to contribute as a student QA.
