How I workprinciples.md
- 01
You hear bad news early, and with a plan.
Every incident gets a root cause, not just a workaround.
- 02
No translator between you and your developers. That’s my job.
I can write the ticket, the code, and the status update.
- 03
AI makes me faster. Experience keeps it honest.
I use AI coding tools every day and review everything they write. I know what to throw away.
