I already host a working WhatsApp API platform with full source code, but the project has grown messy and is missing several key functions. I need an experienced developer to clean up the current installation, restructure the codebase for long-term maintainability, and then layer in new capabilities. CRM & Automation – Build a lightweight CRM inside the same stack, focusing on solid Contact Management and Customer Support Management flows. – Add automation options for drip campaigns so I can trigger sequences from tags, dates, or webhook events. Multichannel AI Chatbot – Extend the existing WhatsApp logic to an AI-driven chatbot that answers on WhatsApp, Instagram, and Facebook from one central brain. NLP, intents, fallback responses, and simple training UI are all expected. Control Panels – Create an admin panel featuring User Management, an Analytics Dashboard, and full Settings Customization so I can tweak limits, keys, and message templates without touching code. – Include a reseller panel that lets me spin up sub-accounts, set message quotas, and brand each workspace. – Integrate a basic billing section to handle plan assignment, usage tracking, and webhook callbacks to my payment gateway. Hosting & Deployment Everything must run on my current server. You will document each step so I can reproduce the deployment on staging or a new VPS. Deliverables 1. Refactored, well-documented codebase running on my host 2. In-app CRM with contact + support modules 3. AI chatbot connected to WhatsApp, Instagram, and Facebook 4. Admin panel with user, analytics, and settings features 5. Reseller panel and billing module 6. Post-deployment walkthrough and installation guide Once live, I’ll verify smooth multichannel replies, contact syncing, and accurate usage reports before releasing final approval.
