Automatizar conversaciones de DM usando GPT-4 (OpenAI) con flujos predefinidos (preguntas de calificación, CTA, seguimiento). Gestionar leads en un dashboard con estados (nuevo, hablando, calificado, agendado, perdido). Ver estadísticas e informes (tasa de conversión, mensajes respondidos, llamadas agendadas). Permitir intervención humana (un agente puede tomar la conversación en cualquier momento). Subir links, videos y documentos que el asistente pueda compartir automáticamente. Requisitos técnicos: Frontend: React.js (preferible [login to view URL]) para dashboards y UI. Backend: Node.js (Express) o Python (FastAPI/Flask). Base de datos: PostgreSQL o MongoDB. Integración con Meta Graph API (Instagram Messaging), incluyendo webhooks. Integración con OpenAI GPT-4 para respuestas naturales. Infraestructura SaaS básica: login multiusuario, roles, gestión de suscripciones. Hosting: AWS / DigitalOcean / Render. Buenas prácticas: código seguro, manejo de límites de API, documentación clara. ✅ Por favor aplica solo si tienes experiencia previa con proyectos de IA en la API de Meta/Instagram y puedes mostrar ejemplos de dashboards SaaS con IA que hayas construido.

I've successfully built several SaaS platforms leveraging React.js, Node.js, and Python, including a similar project integrating AI-powered message automation for a client's Instagram marketing. My experience includes robust API integrations, database design (PostgreSQL preferred), and deployment using AWS/Azure. My approach will involve building a scalable and maintainable architecture using React.js for the frontend, Node.js (or Python, depending on your preference) for the backend, and a chosen database for optimal performance. I'll integrate pre-trained AI models for message automation and implement robust security measures to ensure compliance with Instagram's API and data privacy regulations. Testing will incorporate unit, integration, and end-to-end strategies throughout development. Let's discuss this project further. Could you share details regarding your existing infrastructure and specific AI automation requirements for Instagram messaging, so I can tailor a solution perfectly aligned with your objectives?

Hi, This is Elias from Miami. I’ve gone through your project details, and from what I understand, the goal is to build a SaaS platform combining a CRM and AI-powered chatbot for Instagram, where users can automate DM conversations with GPT-4, manage leads, track statistics, and allow human intervention when needed. I have over 10 years of experience in full-stack development (React.js + Node.js/Python) and have delivered SaaS dashboards with AI integrations, webhooks, and secure multi-user systems. I’d love to help bring this platform to life efficiently while keeping it scalable and maintainable. A few questions to clarify your requirements: Q1: For DM automation flows, do you envision dynamic branching based on user responses, or mainly linear pre-defined sequences? Q2: Should the system store conversation history long-term for analytics, or only aggregate metrics like conversion rates? Q3: For content sharing (links, videos, docs), do you need a built-in media library or integration with external storage like S3/Drive? Looking forward to connecting and discussing the best approach for this AI-driven SaaS. Regards, Elias
