Ask HN: Has anyone built an autonomous AI operator for their side projects?

I spent the last month building what I call an AI operator - an autonomous agent that manages my side projects end-to-end while I focus on strategy. It runs on a 30-minute heartbeat loop, publishes daily blog posts, monitors Stripe for sales, checks sites are up, and does directory submissions. It knows when to escalate to me (financial decisions, strategic pivots) and when to just handle things. The hardest part was writing the decision tree - not the AI itself but defining what it owns vs. what needs human judgment. Current setup: main agent handles orchestration, a builder sub-agent handles code/deploys, an amplifier handles content/social. Revenue is small so far ($200 from PDFs) but the system works while I sleep. Curious if others have gone down this path and what broke for you.
