I need a full-stack, browser-based SaaS platform that allows my client companies to handle every stage of their customer-engagement cycle from one place. The same interface must let them: • Send and schedule mass communications through the WhatsApp Business API, complete with opt-in/opt-out handling. • Import survey response databases in .CSV or .XLSX format, automatically clean and normalise the fields, and map contacts to WhatsApp numbers. • Build fully customisable surveys (question types, logic jumps, branding) and distribute them instantly via WhatsApp or sharable links. • Render results in real time through interactive dashboards—filters, cross-tabs, export to PDF/Excel—so managers can drill down without extra tooling. • Query their own data in plain language through a lightweight AI assistant (OpenAI, Bard, or similar) that returns charts, key metrics, and narrative insights. All modules must work together seamlessly; no separate log-ins or fragmented UIs. A multi-tenant architecture with role-based permissions, Stripe-ready subscription tiers, and usage analytics sits underneath. Acceptance criteria 1. Production-ready web app (React or Vue + Node, Django, or comparable stack) deployed to AWS, GCP, or Azure. 2. WhatsApp bulk-send throughput demonstrably meeting Meta rate limits. 3. Data import pipeline that flags and corrects common formatting issues automatically. 4. Survey builder covering single-choice, multi-choice, rating, NPS, and open text questions, plus skip logic. 5. AI assistant answering aggregation queries (“show churn by region”, “compare NPS this month vs last”) in under 10 seconds. 6. Clean, responsive UI and concise developer documentation. When you reply, focus on experience creating multi-tenant SaaS products that integrate messaging APIs, survey engines, or data-driven AI features. Links to live apps or code samples demonstrating similar functionality will carry the most weight.

Hi There, 1.I need a full-stack, browser-based SaaS platform that allows my client... ==> We have reviewed the details for your SaaS platform. We have built similar systems before and can deliver this. One past project included a feature to make surveys more like a game, which greatly boosted user completion rates. We can create the custom survey builder with logic jumps and a real-time results dashboard. The AI assistant that understands plain language queries is an excellent idea, and we will integrate a fast AI model for this. We are experienced in building multi-tenant apps with user roles and Stripe integration. For the backend, we suggest using Node.js because it is very efficient for real-time applications like this. ## Queries : 1. For the data import, could you provide some key examples of the common formatting issues that need to be automatically corrected? ## Initial Project Structure : - Dashboard - WhatsApp Campaigns - Contacts - Survey Builder - Analytics - AI Assistant - Billing - Team Management We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

Hello, I specialize in building multi-tenant SaaS platforms that combine messaging APIs, survey engines, and AI-driven analytics within a single cohesive system. I would architect this solution using React + Node.js (NestJS) or Django, PostgreSQL with strict tenant isolation, and a modular service layer for WhatsApp Business API integration, high-throughput messaging queues, survey logic, and real-time analytics dashboards. The data import pipeline would include automated cleaning/normalization (CSV/XLSX parsing, schema mapping, deduplication), while the AI assistant would leverage OpenAI with structured query generation over your database to return charts, metrics, and narrative insights in under 10 seconds. Deployed on AWS or GCP with Stripe-ready subscription tiers, RBAC, usage metering, and clean documentation, the platform will be production-ready, scalable, and designed for seamless user experience without fragmented modules; I can share relevant SaaS examples demonstrating messaging automation, survey builders, and AI-powered analytics.

Good to see this project, I will build the multi-tenant SaaS platform with WhatsApp bulk messaging, a survey builder with skip logic and branding, real-time analytics dashboards, and an AI assistant for plain-language data queries all under one interface with Stripe subscriptions and role-based access. For the WhatsApp module, Meta enforces per-number throughput tiers and quality ratings that drop if recipients flag messages. I will build the send queue to throttle dynamically based on each tenant's current tier and quality score from Meta webhook feedback, rather than a fixed rate that wastes capacity or triggers penalties. Questions: 1) Do you have a WhatsApp Business API account and approved templates already? 2) For the AI assistant, any preference between OpenAI and Google? 3) How many tenant companies do you expect at launch? Looking forward to discussing further. Best regards, Kamran

Built a multi-tenant SaaS with WhatsApp Business API before - bulk messaging, opt-in/out handling, real-time dashboards, RBAC. So most of this is familiar territory. Stack-wise: React + Node.js on AWS, Stripe for subscriptions, OpenAI for the AI query layer. Survey builder with logic jumps, NPS, multi-choice - all standard. The CSV/XLSX import pipeline with auto-cleaning and WhatsApp number normalzation is doable. WhatsApp throughput needs careful queue management to stay within Meta rate limits - happy to walk through the architecture before we commit. Bid is $4,500, can scope more precisely after a quick call. - Usama
