NowThe Shift
Why QA caught my attention
The rise of AI made me rethink the software development process as a whole. If generating code becomes easier, then quality, validation and reliability become even more important.
QA Automation caught my attention because it sits exactly at that intersection: engineering, product thinking and confidence in what we ship.
AI can accelerate development. Quality engineering ensures what we build can be trusted.
