I need an end-to-end solution that lets diners interact with my menu through an AI chat interface and, on demand, download a polished PDF report of the same menu. Here is what I have in mind: • AI chat feature – The user types a question about any item on the menu and instantly receives a concise, friendly answer. Think of it as a waiter who never sleeps. You are free to use OpenAI, LangChain, or another framework as long as latency stays low and answers remain accurate. • One-click PDF report – From the same interface, the user should be able to export the full menu to a neatly formatted PDF. All menu sections, names, prices, and descriptions must carry over exactly as stored in the database or file you connect to. I will provide the raw menu data (CSV, JSON, or ...

I need an open, fully documented REST-style API that can sit between Ship ERP and our in-house Truck Management System, letting the two platforms talk to each other in real time. The core responsibilities of this new layer are: • Real-time status updates – the moment a shipment moves, both systems must reflect it. • Data synchronization – orders, loads, and reference data must stay consistent on both sides. • Rate engine – an endpoint that can accept lane details, weight, and accessorial flags, then return our calculated rate instantly. Key data points that the endpoints must expose or consume include tracking numbers, current shipment status, and system-generated rate calculations. Technical expectations – JSON over HTTPS; versioned endpoint...

I need a lightweight but reliable auto-responder for Facebook Marketplace Messenger. Every new inquiry should receive an English-language greeting that quickly qualifies the lead and then drops a link to my scheduling form so the prospect can choose a time that goes straight onto my Google Calendar. The must-haves for this first milestone are: • Detect the first incoming message on Marketplace chat and fire the greeting within seconds. • Insert my pre-written text plus the scheduling-form link (I currently use Calendly, but Zapier, ManyChat or native Meta tools are fine if you can achieve the same result). • Ensure the booked slot is created as a standard Google Calendar event with the prospect’s name and Messenger handle for easy follow-up.

My production API is running on Node 16, and I now need it fully upgraded to Node 22. The jump breaks several dependencies—some are deprecated, others removed entirely—so the work goes beyond just bumping versions. You will: • Analyse the current dependency tree, pin what still works, and replace or manually migrate anything that no longer compiles under Node 22. • Refactor hotspots you encounter for cleaner, faster execution; I’m aiming for measurable performance gains once the codebase is modernised. The application is an API service only (no UI), deployed through a typical CI pipeline, so the deliverable is a clean, install-and-run repository passing the existing test suite under Node 22. If you’ve already handled major LTS jumps and know ...
