Je vais réparer ou développer une application Ruby on Rails

I build AI that does real work for businesses: voice agents that answer your phone and book customers, chat assistants that handle support 24/7, and automations that remove manual steps from your day. Recent build: an AI phone receptionist taking live calls for a US hospitality business. It checks real availability, quotes the price, sends a payment link, completes the booking, and hands off to staff when a caller needs a human. Production engineer first. I handle the unglamorous parts: guardrails, error handling, cost control, monitoring. Tell me what you want to stop doing by hand.
