- Automate what's repetitive, validate what matters
- Collaborate like a dev, think like a user
- Quality is a shared responsibility
- The most critical bugs aren't always the most visible
Testing frameworks, proof-of-concepts, AI-powered testing tools, CI/CD utilities, and real-world examples built for actual QA workflows — from E2E automation to LLM evaluation pipelines.
