WhatsApp BSP-level Project develop

@mayankinnovative

Hi, As per my understanding: You are building a BSP-level WhatsApp API platform at Surefy and need to scale it into a WATI/AiSensy competitor. You need a comprehensive system featuring a flow builder, shared inbox, campaign management, and LLM-driven automation. You require a scalable, multi-tenant architecture capable of high throughput, complex Meta API webhooks, and seamless CRM integrations, all while ensuring high delivery rates and strict compliance. Implementation approach: I will build a modular system using Node.js and RabbitMQ to handle high-volume throughput. I will develop a node-based flow builder for chatbot logic and implement a multi-tenant PostgreSQL schema for inbox and campaign modules. I will build an AI middleware layer for smart routing and integrate Meta Cloud API webhooks with robust retries. My focus is on high availability and rate limit management to keep quality scores high while ensuring the system remains extendable for future CRM and third-party integrations. A few quick questions: 1. What infrastructure or message queue system does your current architecture utilize? 2. Do you have a preferred library or framework for the flow builder frontend? 3. What is your current messaging volume and targeted number of concurrent WABAs?

Hi, As per my understanding: you need to evolve your WhatsApp BSP platform with advanced automation, multi-tenant architecture, deep API integrations, and scalable messaging workflows. Approach: * Node.js microservices + queue-based messaging system * Meta API/webhooks, multi-WABA setup, CRM integrations * Flow builder + AI chatbot with analytics layer Queries: * Current infra/queue system in place? * Expected message volume scale? I will share my portfolio on your first message. I will be looking forward to hearing from you. Kindest Regards

Hi there! You are building a BSP-level WhatsApp communication platform and the real challenge is not just integrating the WhatsApp API, but designing a scalable multi-tenant messaging system that can handle automation, high throughput, and real-time event-driven workflows like AiSensy or WATI. I recently worked on a SaaS messaging system with webhook-driven architecture and queue-based message processing, where we improved delivery reliability, built structured campaign flows, and implemented CRM-style contact segmentation with scalable backend design. I will enhance your existing Surefy modules by building advanced WhatsApp automation flows, strengthening Meta Cloud API integration, designing webhook-based event handling, and improving system scalability with proper queueing, logging, and multi-tenant architecture support for future growth. Check our work: https://www.freelancer.com/u/ayesha86664 Have you already finalized whether you want a single WABA multi-number architecture or a fully isolated multi-tenant setup per client? I am ready to start — just say the word. Best Regards, Ayesha

Hi there, I have read your project requirement. You need to enhance and scale your WhatsApp Business API platform into a full BSP-level system with advanced features like campaign management, chatbot automation, flow builder, multi-WABA support, analytics dashboard, and high-performance messaging infrastructure. We can build a scalable solution using Node.js (NestJS) with PostgreSQL and a queue-based architecture (RabbitMQ/Kafka) to handle high-volume messaging, webhooks, retries, and rate limits. The platform will include automation flows, shared team inbox, contact segmentation, AI-powered chatbot (OpenAI integration), and seamless integration with Meta WhatsApp Cloud API and external systems like CRM. A few questions to clarify: ==================== Are you currently using Meta Cloud API or On-Prem WhatsApp API? Do you already have any queue system (RabbitMQ/Kafka) implemented? How many WABA accounts/numbers do you plan to support initially? Do you want a visual drag-and-drop flow builder from Phase 1? Best Regards, Srashtasoft Team
