Switched from manual QA to dev after two years and I wish I'd done it sooner
Spent two years in manual QA feeling like I was watching everyone else build things. Started fixing tiny bugs in the test tooling, then automating checks, then one day a dev asked if I wanted to pick up a real ticket. Six months later I moved teams as a junior.
The QA background turned out to be a cheat code. I write way more defensive code and I actually think about edge cases before the reviewer does. If you're stuck in a testing or support role and eyeing dev, the path is shorter than it looks. Happy to answer questions.
