I've created chatbot applications to several companies, over multiple channels, such as Skype and Skype for Business, Facebook Messenger, Telegram and for custom websites. I create chatbots that provide simple and complete features, such as conversational structures and dialog trees, integration with existing APIs (for gathering leads and information, do something for the user, etc). Creating a chatbot it's not a very complicated task, creating a good chatbot it's a tricky one, I can help you with that.
