Hi there!
I am a chatbot developer in the number one chatbot development agency in the Philippines. I basically create chatbots on Facebook Messenger Platform on a daily basis. For your project, what we can do in this project is that, for the chatbot creation, I can start creating the bot flow on day 1 in Chatfuel. Chatfuel is the leading bot platform for creating AI chatbots for Facebook and it has a free tier with most of the functionality needed in this project. For the 2nd day, I will create an API that integrates the bot with DialogFlow. DialogFlow is Google's best Natural Language Processing Platform, using this API will be a best fit for the bot in answering user inquiries. I can also teach you on how to train the bot using the DialogFlow console to make the bot smarter in answering questions. On the 3rd day, I will create a Middleware API for intercepting the photos sent by the user. We can further discuss the functions of this middleware but initially it will be used to store the photos. All of the APIs will be written in Node.js and will surely make use of Facebook Graph API The 4th day will just be API integrations and overall testing.
I'd like to know more about how we can work together to put out a great bot that would benefit your facility.
Hoping to work with you soon!
