QA Engineer at Streamtek testing microservice-based web and mobile apps, from API behavior to production stability.

At Streamtek, I test a microservice-based web application and mobile apps across emulators and real devices. I use browser DevTools to investigate API calls and network activity, and maintain test coverage for core user flows.

At Growave, I tested features and third-party integrations across web, mobile, and desktop, including REST APIs with Postman and data validation with MySQL. I also created test cases, checklists, and bug reports, and supported onboarding new QA team members.
