thanks! Most of these projects are hosted on Vercel, and I am extensively using their observability solution to get alerts when something unexpected happens. After some time you get to fix everything and you'll spend less time firefighting.

For customer queries, I usually respond myself. However when I am not available, I have a small team of freelancers that help me just with that. I played with LLMs for responding to questions, but it just didn't work out for me.
