Things No One Told Me About QA
How to care, lead, and not burn out
The parts of QA no one explains: carrying too much, asking alone, leading without the title — and still showing up.
This is not a technical guide. It’s not a framework handbook. This isn’t a manual. It’s a mirror.
For those who’ve learned the hard way that quality has a cost — and it’s not just technical.
