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.

Hi there! I have 10 years of full-stack development experience and can build the responsive platform with chatbot flows, human handoff, campaign scheduling, personalised templates, conversation logs, quota management, billing status, and integration-ready APIs. For WhatsApp connectivity, I’d first confirm the integration method. For a production commercial platform, I’d recommend using Meta’s supported WhatsApp Business Platform/API rather than promising WhatsApp Web QR session automation or “500 messages without bans,” since account restrictions ultimately depend on WhatsApp’s policies and messaging rules. I can structure the chatbot and messaging layers modularly so an NLP/AI engine can be added later, with Docker deployment, admin documentation, real-time dashboards, plan-based quotas, and campaign analytics included.

Hi, The main challenge here is keeping each WhatsApp session reliably active in the cloud after QR pairing, while handling chatbot conversations and scheduled bulk campaigns without mixing the two workflows. I can build the reonspsive web platform with persistent QR-based sessions, live conversation handling, rule-based chatbot flows, bot/human handover, reusable templates, merge fields, scheduled campaigns, and real-time quota tracking. The quota system can be plan-based, so the 500 unique messages/day limit is enforced automatically for free users and adjusted according to the selected paid plan. The dashboard can cover connected WhatsApp accounts, conversations, campaign performance, daily usage, and billing status, with REST/GraphQL endpoints available for future integrations. I’ll also provide Docker-based deployment instructions and an admin guide. For the acceptance testing, I’d specifically validate the 500-message workflow and 20+ simultaneous sessions/connections, along with session recovery and campaign scheduling. Could you confirm which WhatsApp integration/API approach you expect for the QR pairing flow and whether billing/payment integration is already decided? I’m available to start immediately.

Hi there, Your project "Web WhatsApp Automation & Chatbot" instantly caught my attention — it's exactly the kind of work we love to take on. What stood out to me is how clearly you’ve described what you want — and clarity like that is where we deliver our very best work. From your brief I can see this involves web app, react, node — all areas we handle in-house. We specialise in PHP, Java, Python, Node.js, which lines up directly with what you need. How we'd approach it: - Map out the scope, pages and data models up front - Build the frontend and backend with clean, scalable code - Test across devices and browsers, then deploy - Hand over with documentation and post-launch support I also noted you don’t need keeping a browser open locally — that’s clear, and I’ll keep the work clean and strictly on-brief. Delivering at the scale of 500 unique is no problem for us — we're set up for volume without dropping quality. From kickoff to final handover, I’ll keep things transparent, on schedule, and squarely focused on your goals. Happy to jump on a quick chat to walk through scope and timelines whenever suits you.

Hi, I'm a Software Architect with 11+ years building backend automation and chatbot platforms at scale. I understand the real challenge here: keeping a WhatsApp Web session alive in the cloud reliably, with rule-based flows now that can later plug in an NLP engine without a rewrite. Given the scope, I propose Phase 1 (this bid): QR-based cloud session pairing + the rule-based chatbot module with conversation logging. Phase 2 would add the bulk messaging/campaign module with quotas and billing. What I'll deliver in Phase 1: - Web app with QR pairing, session kept alive server-side - Rule-based chatbot flows, swappable for NLP later - Conversation logging tagged for human hand-off - Dashboard shell for live conversations Quick question: are the contact lists for the (Phase 2) bulk messaging module opt-in / existing customers, or cold lists? That affects the sending architecture (rate limits, opt-out handling) I'd design for. I work fast and deliver exactly what you need. Let's build this right.

Hi, I notice that handling WhatsApp's rate limits and avoiding account bans will be crucial, so I'd approach this by implementing a real-time message queue that throttles sends based on the user's plan and WhatsApp's own limits. This way, we can prevent accidental flooding and ensure a smooth experience. I'll set up a system to track message quotas and automatically prompt upgrades when necessary. In my experience, a common mistake is not properly handling concurrent conversations, which can lead to missed messages or bot responses, so I'll make sure to implement a robust conversation management system that can handle multiple chats simultaneously. As a result, the client can expect a reliable and efficient web-based WhatsApp automation and chatbot platform that meets their requirements and provides a good user experience.

Hi, I can build this as a scalable web-based WhatsApp automation platform with a responsive React frontend and Node.js backend. The platform can include QR-based WhatsApp account pairing, persistent cloud sessions, live conversation management, rule-based chatbot flows, human handover, message logging, reusable templates, contact imports, merge fields, scheduled campaigns and real-time quota tracking. I can design the architecture so the current rule-based chatbot can later be extended with an NLP/AI engine without rebuilding the core system. The backend can also manage per-account plans, daily quotas, billing status and REST APIs for future integrations. The dashboard will provide conversation monitoring, campaign statistics, quota usage and account status, with Docker-based deployment and clear documentation. For bulk messaging, I’ll structure the system around appropriate WhatsApp platform policies and rate controls rather than relying on methods that could put connected accounts at risk.

I can build this as a scalable web platform with QR-based WhatsApp pairing, persistent cloud sessions, chatbot automation, bulk messaging, quotas, and a responsive admin dashboard. I’ll structure the chatbot with a rule-based flow engine first, keeping the architecture modular so an NLP/LLM layer can be added later without rebuilding the core system. Bot conversations will be logged and tagged, with seamless human takeover when required. For bulk messaging, I’ll implement contact import, reusable templates, merge fields, minute-level scheduling, campaign tracking, delivery status, and real-time per-account quota enforcement. The free plan will enforce the 500 unique-message daily limit, while plan-specific quotas can be managed from the backend. The platform will include secure session management, REST/GraphQL APIs, billing/quota handling, Docker deployment, admin documentation, and a responsive dashboard for conversations, campaigns, usage, and account status. I’ll also design the messaging layer for concurrent chatbot sessions and proper error handling, retries, logging, and monitoring. One important point: I’ll use the appropriate WhatsApp integration approach and ensure the implementation follows WhatsApp’s supported policies and messaging limits rather than designing around ban avoidance.

When 500 personalised messages, live support chats, and quota checks are all running at once, the main challenge is keeping sessions, automation, and usage limits reliable without making the dashboard difficult to operate. The platform can be structured around persistent WhatsApp sessions, a rule based flow engine with a clean handoff point for future NLP, and a campaign service that handles templates, merge fields, scheduling, and real time plan quotas. The dashboard can bring conversations, bot activity, campaign performance, billing, and the 500 message free tier into one place, with Docker based deployment and API endpoints prepared for future integrations. A comparable messaging system handled 20+ concurrent automated conversations while maintaining message logs and per account usage tracking. Would you prefer the WhatsApp connection built around the official WhatsApp Business Platform or the WhatsApp Web QR pairing flow specified here?

Hi, Keeping a user's WhatsApp account active after QR pairing, while running customer support and scheduled messaging in the cloud, needs to work reliably without forcing them to keep a browser open or lose conversations during automation. I’d structure the platform around persistent sessions, a separate chatbot flow engine, queued campaigns, message logging, and real-time plan quotas. That also leaves the chatbot layer open for an NLP engine later without rebuilding the core system. Before development, I’d want to confirm the WhatsApp integration method you expect for the QR-based pairing, as that will determine the session and deployment architecture. Regards, M. Hasan
