Agile: Quality Clean-Up in Development

Did you find yourself in a new company that switched to Agile? Or did your place of work decide to take up “agile development” and now you are part of the Scrum Team? And now you are the main on testing in the team, as the only tester. And most importantly, after implementing Agile, you test even more, but still, the quality of the product is not very good? And the manager, thinks to bring another tester to help you? But the quality of the issued product is still "not very good." What to do? Test even more and faster? But how? You are one, and there are many of them (developers). The short answer is to forget about testing and really tackle quality. How? I will talk about this in my talk.
