I am ready to build out a tailored WhatsApp-based solution and would like an experienced professional to guide and execute the technical work from start to finish. I have not locked myself into a single approach yet—this could take the shape of a lightweight chatbot, a full Business API integration, or even a promotional automation flow—so I’m open to your strategic input on the best route. Here’s what I need from you: • A quick discovery call or written outline clarifying the recommended architecture, tool stack, and any required WhatsApp Business verification steps. • Implementation of the agreed approach (whether that involves Twilio, Meta Cloud API, Node.js, Python, or another stack you prefer). • A clean hand-off package that includes tested code, clear installation instructions, and brief user documentation. Acceptance criteria will be a working WhatsApp endpoint that I can trigger or interact with live, plus the documentation mentioned above. If you can demonstrate previous WhatsApp deployments, that will help me choose swiftly.
