Have you worked with manual testing or tried automation and load testing?

In my practice, I started with manual testing, which helped me understand the product more deeply and identify bugs early on. Later, I tried automation using tools like Selenium and pytest for writing automated tests, which significantly sped up regression testing and increased its reliability.

I also have experience with load testing using JMeter and Locust to see how the system behaves under high load and to identify bottlenecks in performance. This allowed me to optimize server operation and improve user experience.
