February 2021 - September 2021 (8 months)
Abidjan, Côte d’Ivoire
Within this project, I was responsible for setting up the server that handled authentication, authorization, token management, and data synchronization and flow between the server and the application.

I used Node.js as the technology to work in this area. To facilitate the process, I opted for Express, and for data processing, I chose a non-relational prototype, MongoDB.

I also developed a RESTFUL API with the help of POSTMAN to facilitate the integration process between the frontend and the backend via the microservice.
