Objective: To build an unofficial mass trigger for WhatsApp (front-end + back-end) with clickable buttons for external links, using Node.js + TypeScript + MySql (preferred). If there is a strong technical justification, the developer may propose an alternative language. Note: The system is not for market commercialization but for internal team use. Note: The project details are in the attached file. If you have any questions, I am available to answer them. Questions: What is your availability to start creating the project? How long do you estimate to complete the project?
