• Perform a wide range of testing activities, including functional testing, API/interface testing, performance testing (load, concurrency, stress, stability), and security testing.

• Utilize performance testing tools such as JMeter, LoadRunner, and Gatling to assess system performance, identify bottlenecks (CPU, memory, database), and propose optimization solutions.

• Record, monitor, and manage defects using defect tracking tools like JIRA, ensuring issues are resolved and fixes are properly validated.

• Work closely with development, product, and operations teams to review requirements and ensure software quality aligns with expected standards.

• Produce comprehensive test and performance analysis reports detailing test progress, coverage, quality status, and recommendations for improvement.

• Hands‑on experience with test management tools (JIRA, TestRail), API testing tools (Postman, SoapUI), and performance testing tools (JMeter, LoadRunner, Gatling).

• Programming capability to create automated and performance test scripts using Python, Java, JavaScript, or Shell.

• Solid knowledge of functional, API, and performance testing approaches, with a good understanding of security testing concepts and system architectures (web applications, databases, servers).

• Strong analytical and problem‑solving skills, with the ability to clearly document defects, reproduce issues, and diagnose performance problems.

• Familiarity with Linux environments, including the use of basic system monitoring commands such as top and vmstat.

• Excellent communication and collaboration skills, with the ability to work effectively in Agile development environments and cross‑functional teams.
