QA / test automation engineer with ~9 years across e-commerce, corporate travel, and regulated gaming. I build full-stack test automation with Playwright and TypeScript — covering UI, REST APIs, and databases — and bring performance and messaging-based testing (k6, Kafka, Azure Service Bus) to systems that need it. I build the QA tooling and dashboards a team needs rather than waiting for them.
