🧭 About me

I'm a QA Engineer who investigates products end to end — from the interface down to API contracts, databases, logs, asynchronous flows and third-party integrations.

I focus testing on business risk: payments, access control, state transitions and failure recovery. My reports connect a visible symptom to technical evidence and a clear release decision.

Good testing is not about clicking through every screen.
It's about understanding what can break — and proving what actually broke.
