MazarsDecember 2019 - January 2020

Following my chatbot experience at Accor, Viseo sent me to Mazars for a 25 days mission in order to setup a Chatbot for the Standards service.
The problem to solve is as follows : Mazars consultants often have questions around standards, which saturates the service. The documentation is exhaustive but complex and some questions have to be rerouted to the appropriate service.
My missions were :
- Setup the Bot architecture (NodeJS in micro-services, scalable and evolutive)
- Connect it to Teams via Azure
- Setup the tools and teach the teams so that they can be autonomous :
* DialogFlow (Natural Language Understanding tool)
* Firebase (for the bot language dictionnary)
* Teams App Studio
- Writing an extensive documentation on the project's Readme, to enable future evolutions
