Hi, Your description cuts off mid-sentence, which makes it hard to scope accurately — but the core need is clear: a WhatsApp automation backend that handles messaging programmatically at scale. For the integration layer, I'd use the official WhatsApp Business Cloud API (Meta's hosted solution) with webhook handlers built in Python/FastAPI. This avoids brittle unofficial libraries and gives you proper message status callbacks, template message support, and media handling out of the box. I'd back it with a lightweight Postgres schema for contact management and message logs, plus a simple job queue (Celery + Redis) if your use case involves scheduled or bulk sends. Before going further, I need to understand the actual scope: How many contacts? Inbound replies, or outbound-only? Any CRM integration? The $600 budget works for a focused MVP — a working webhook receiver, send/receive endpoints, and a basic admin interface — but not for a full-featured platform. If you can share the complete requirements, I can tell you in 24 hours exactly what fits within budget and what would need to be phased. Best regards, Val

Hi there, WhatsApp automation platforms usually fail when bulk messaging, chatbot flows, scheduling, and live communication are not designed under one stable backend, so the key here is building a scalable system where campaigns, automation, and customer conversations stay synchronized without delivery or performance issues. A React and Node.js backend with secure WhatsApp API integration and Flutter mobile app would fit this well, especially for handling campaign management, chatbot workflows, scheduling, reporting, and multi-device usage cleanly at scale. I’ve already worked on similar messaging and automation systems involving real-time communication and workflow-driven chat handling. Are you planning to use the official WhatsApp Business Cloud API only? Happy to connect and discuss the architecture further. Kind regards, Nikunj
