I test mobile and API systems, uncovering critical security and integration defects.
KazakhstanWhat I'm looking for
At ZITZER&SON, I test an Android biometric verification app and its backend services for a public-sector workforce. Through negative API testing in Postman, I uncovered a critical flaw that allowed a foreign face to register attendance; it was fixed the same day.
I've driven automation coverage of critical functionality to 70%+ using pytest, Playwright, and Allure TestOps, while validating integrations, push delivery, messaging flows, PostgreSQL data, and production logs and metrics. Earlier, I tested access-control and video-surveillance systems with real hardware at ZITZER&SON and live sports content and real-time data flows at the Russian Premier League.

• Traced lost access events across a Kafka chain (produce
