Your goal to unify member sign-up and verification across mobile, website, and WhatsApp makes a lot of sense for smooth user experience. For the app, I can build a sign-up flow integrated with WhatsApp Business API that collects user info and triggers Aadhaar OTP verification efficiently. Generating a unique QR code per profile won’t slow the process and will tie seamlessly to the user record. I’ve done similar work for a community org where we kept all user data in a single back-end, eliminating manual syncing headaches and ensuring consistent profiles across their app and web portal. A key step will be designing the API layer so that both your future Vanshvali website and WhatsApp bot can pull from and push to the same database. For the WhatsApp bot, I suggest a straightforward flow focusing first on registration and data confirmation, with fallback to a simple FAQ. Have you considered which OTP/Aadhaar service you want to use, and how flexible your WhatsApp API usage limits are? Handling bilingual conversation smoothly without delays will be crucial. I’m ready to start with the app milestone and get your users signing up via WhatsApp quickly while keeping data synced. Let me know if you want to discuss data security or hosting preferences early on.

I can build this with a centralized backend architecture so your mobile app, Vanshvali website, and WhatsApp bot all read/write from the same source no duplication, no sync issues. The first phase will focus on a stable mobile app with WhatsApp-based onboarding, QR generation, and OTP verification, ensuring the core flow works flawlessly before expanding. The system will include secure user registration, dynamic QR tied to each profile, Aadhaar OTP integration, and a bilingual-ready structure (Hindi/English). Once the app foundation is validated, the website and bot will plug into the same APIs, maintaining consistency across all platforms. To align perfectly: Which Aadhaar verification service/provider are you planning to use? Do you already have access to WhatsApp Business API or need setup assistance? Should the first version of the app be Android-only or cross-platform? If the goal is a system that is stable, scalable, and truly unified across app, web, and WhatsApp, I can structure and deliver it properly. Looking forward to hearing back from you and discussing this in the chat. Portfolio: https://www.freelancer.in/u/Rupal878 Rupal Saini
