I want a web-based platform that lets any user connect their own WhatsApp number simply by scanning the standard QR code (the same flow WhatsApp Web uses). Once paired, the account should stay active in the cloud so the user can keep sending and receiving without keeping a browser open locally. Inside the app, two core modules are required: 1. Chatbot The built-in bot must be able to respond to common questions, automate day-to-day customer support, and guide users through multi-step processes. I should be able to create rule-based flows now and, if I decide later, swap in an NLP engine without major refactoring. Messages handled by the bot need to be logged and clearly tagged so the user can jump into any conversation when human intervention is needed. 2. Bulk Messaging Users will upload or paste contact lists, choose from reusable message templates, personalise each send with merge fields (name, order number, etc.), and set a schedule—down to minute precision—before launching a campaign. The system must track how many messages each account has sent and automatically cap the free tier at 500 unique messages per day, prompting an upgrade when the limit is reached. Higher plans simply lift that ceiling, so the architecture has to store per-plan quotas and check them in real time. Core expectations and deliverables • Responsive web app (desktop and mobile) • Secure session handling for the QR-based login • Dashboard showing live conversations, campaign stats, quota usage, and billing status • REST or GraphQL API endpoints for future integrations • Clear deployment instructions (Docker-compose or similar) plus a brief admin manual Once the system passes functional tests—sending 500 personalised messages in a day without bans and handling at least 20 simultaneous chatbot conversations—the project will be considered complete.

When a project involves user engagement through messaging and automation, the real challenge often lie in making sure scalability while maintaining a secure and responsive experience. To adress potential concerns about user data and message limits, I will implement solid session management and make sure the system adheres to the 500 unique messages per day cap without disrupting existing user interactions. Phased approach: Initial setup: Configure the web app and Docker-compose for a secure environment. Chatbot development: Build the rule-based chatbot with logging and tagging features. Bulk messaging module: Implement contact upload, template management, and scheduling. Testing and deployment: Conduct functional tests and provide deployment instructions. I am ready to work remotely via AnyDesk or TeamViewer if required. My bid for this project is 5899 INR. Rajavel

**I am Anand and I can start your WhatsApp QR cloud platform this week** I build web apps where any user pairs their own WhatsApp number via QR like WhatsApp Web and it stays active in the cloud with no local browser needed. For 1. Chatbot I will build rule-based flows for FAQs support and multi-step processes with a clean interface to swap in NLP later plus full logging and bot-tagged messages with one-click human takeover. For 2. Bulk I will add contact upload/paste plus reusable templates with merge fields like name and order number plus minute-precision scheduling plus live per-account counting that caps free at 500 unique/day with upgrade prompt and per-plan quotas checked in real time. Responsive covers desktop and mobile. Secure covers encrypted session handling for QR login. Dashboard covers live chats campaign stats quota usage and billing. REST covers clean endpoints for future integrations. Clear covers docker-compose deploy plus short admin manual. Recent work: salon booking bot handling 25+ parallel chats with handoff; bulk sender doing 500+ personalised sends/day with anti-ban throttling. Can we start with your preferred stack for backend and hosting so I align Docker and API design today.

I see you need a web platform using WhatsApp Web QR authentication to handle automated chatbots and scheduled bulk messaging with strict daily rate limits. I've built WhatsApp automation systems using Node.js and Redis queues, implementing staggered delay algorithms to prevent account bans while processing dynamic merge fields and account quotas. Are you planning to host the Baileys socket connection natively inside Docker containers, or are you considering a third-party gateway API for session management?

Hi,I am Hassam, a Software Engineer and AI Full-Stack Developer with a BS in Software Engineering and strong specialization in AI/ML. I work with AI agents, automation workflows, APIs, real-time systems and scalable SaaS applications. I understand the core challenge: you need a cloud-based WhatsApp platform where users can connect their accounts, manage conversations, automate support, run campaigns and control usage from one dashboard. I can build: • QR-based WhatsApp session management with secure cloud sessions • Real-time shared inbox and human handover • Rule-based chatbot with architecture ready for NLP/LLM integration • Conversation logging and bot/human tagging • Bulk campaigns with templates, merge fields and scheduling • Per-account/per-plan quotas with real-time usage tracking • Dashboard for chats, campaigns, billing and quota usage • REST/GraphQL APIs for future integrations • Docker-based deployment, documentation and admin manual I would design the chatbot and messaging engine as separate modules so future NLP/AI integration does not require rebuilding the core platform. Portfolio: [https://www.freelancer.pk/u/hassam945?frm=hassam945&sb=](https://www.freelancer.pk/u/hassam945?frm=hassam945&sb=) I prefer to first discuss the technical workflow and constraints, then build and test the platform step by step. Thank you.

You need one web app for live support, chatbot handoff, scheduled campaigns, and plan-based message limits. At Marin Software, I built LangChain automation and real-time pipelines, which fits the conversation and scheduling side of this build. I’d separate messaging, bot flows, campaigns, and billing so an NLP engine can be added later. The dashboard would show tagged bot replies, human handoffs, campaign results, and quota usage; the API and deployment guide would support future integrations. Before implementation, I’d confirm the WhatsApp connection method. A WhatsApp Web-style QR session and a guarantee of 500 sends without bans are requirements I cannot promise. For campaigns, I’d design around the official business platform, recipient consent, approved templates, and measurable delivery results. Can the QR requirement change to official business onboarding, and are the contact lists opted in?

Hi, I hope you're doing well. I understand you're looking to build a cloud-based WhatsApp communication platform combining chatbot automation, campaign messaging, scheduling, contact personalization, quotas, and a centralized dashboard. The important part is designing the messaging layer and account management carefully so the system remains scalable, secure, and maintainable as usage grows. I will build the responsive web platform with secure account/session management, conversation and campaign dashboards, reusable templates with merge fields, scheduling, message logging, plan-based quotas, and REST/GraphQL APIs for future integrations. The chatbot will use a modular rule-based flow engine so an NLP provider can be introduced later without rebuilding the core architecture. I will also provide Docker-based deployment configuration, admin documentation, automated testing, and monitoring for concurrent conversations and campaign processing. My focus is on delivering a reliable, scalable communication platform with clean architecture, clear quota handling, secure implementation, and straightforward deployment and maintenance.
