        These are videos I’ve done.

        1. What is trunk based development?
        2. What are synthetic tests? (synthetic testing (CXA))
        3. What are deploy pipelines?
        4. How long should baketime be?
        5. What’s the role of QA in modern software? (QA)
        6. Fix problems w/ API Mocks w/ contract testing (testing)
