Notes from production.
What building and running business software actually involves, written down while it's fresh.
Running a fleet of devices installed at customer sites, without logging into any of them by hand: one table for the whole fleet, live per-device health, remote controls your support team can use, and deep diagnostics for the bad day. From building FleetDeck.
A calm, practical checklist for business owners whose developer is gone: secure the accounts, test a backup, freeze big changes, map the system before touching it, and find an owner rather than a series of fixers.
Four simple rules I use to run AI features in software people depend on: the AI suggests and a human approves, it reads the real system instead of guessing, every change can be undone, and it stops when it isn't sure. From AccessHub's in-app assistant.
What it actually takes to send bulk SMS in the US without getting filtered or fined: consent, opt-out handling that survives re-imports, working STOP and HELP replies, and A2P 10DLC registration. Written from building it into a real platform.
