• Monitor system metrics (CPU, memory, I/O, network) during test execution.

• Solid understanding of Agile principles and Scrum methodology.
• Proven ability to define, prioritise, and deliver high-quality software features.
• Proven experience in non-functional testing, especially performance and scalability testing.
