amoCRM Trigger Plugin Development

I need an MVP plugin that adds an “Automated Triggers” tab to every contact and deal card in amoCRM. Within that tab I want to create basic time-based, action-based or status-change rules; when any rule fires, the system should merge the contact’s name, company and other fields into a Welcome, Appointment Reminder or Follow-up template, then send the result through Telegram, Email or WhatsApp.

Scope for this first release:
• React + Tailwind widget injected in amoCRM for building and listing triggers
• Node.js service with PostgreSQL to store rules, schedule jobs and capture amoCRM webhooks
• Message delivery via Telegram Bot API, SMTP and a WhatsApp gateway you recommend
• Automatic event logging back to the amoCRM timeline
• A lightweight analytics view that counts messages per contact and per manager

Deliverables:
1. Complete, installable MVP (frontend, backend and integrations)
2. Step-by-step setup & installation guide
3. One month of post-launch bug-fix support

I’ll supply API keys and an amoCRM sandbox. Target turnaround is two weeks.
