Apply Classifier for AI bot
We worked with Bilal, a Senior AI Engineer, to build a RAG-based WhatsApp AI chatbot using Meta WhatsApp Cloud API. He set up the full knowledge base with vector database search so the bot answers accurately from our own data. Delivered on time, professional, and highly skilled. Will hire again.
