We are seeking an experienced full-stack/automation developer to build scalable WhatsApp and website chatbots for end-to-end clinic appointment management. The solution should leverage WhatsApp Business API, web chat widgets, and n8n workflows to handle conversational booking flows, availability checks, appointment creation, reminders, and real-time synchronization with Google Calendar. The system must support dynamic time slot discussions, conflict detection, timezone handling, and automated follow-ups. Developers should design robust webhook-based integrations, secure API layers, and fault-tolerant automation pipelines in n8n for event-driven processing. Experience with conversational UI/UX, LLM/NLP integration, rate limiting, message templates, and multi-clinic scalability is required. The final solution should include audit logs, admin controls, and extensible architecture for future integrations (CRM/EMR). Start with message with "Clinic" otherwise it would be rejected
