Needles

A CRM for tattoo and piercing studios. Live, in beta.

Double booking is impossible. Not checked in the UI: the database refuses it.
  • One schema per studio Tenants never share a table.
  • Encrypted field by field AES-256-GCM, a key per studio.
  • Paperless consent Clients sign on their own phone, via QR.
  • Their own integrations WhatsApp, Telegram bot, Google Calendar.
Needles week calendar with colour-coded bookings per artist. Needles sterilization log: autoclave cycles with pass and fail results. Needles on a phone: today's appointments with live status.

Screens from the public demo, UI in Romanian. Every name in them is synthetic.

  4. Telegram
Silent when healthy. A daily heartbeat whose silence is the alarm.

What it runs

  • A staging copy of Needles that redeploys itself from a stable branch.
  • An AI agent on Telegram that triages alerts and reads my tools over MCP.
  • A phone control panel for both Docker hosts.
  • Ordered recovery after a power cut, written as a runbook.
  • Home automation, media, notes, an RSS digest at 08:00.
