Are you more interested in continuing to work in a familiar area (backend/API) or switching to mobile?

The choice between continuing work in a familiar area (backend/API) and switching to mobile development depends on your goals and interests.

If you enjoy delving deeply into server logic, API architecture, optimization, and scaling — it’s worth continuing to develop in the backend.

If you want to master new platforms, work with UI/UX, mobile frameworks, and mobile OS features — switching to mobile development will offer new challenges and skills.

For QA/QA Automation, this also affects specialization: automating mobile applications requires knowledge of specific tools (Appium, Espresso, XCUITest), whereas backend testing involves API tests, load testing, etc.

It’s recommended to assess what interests you more, what skills you want to develop, and try a small project or courses on mobile automation to see if this direction suits you.
