I worked on that project for 1 year on frontend with React, Typescript, MobX, GraphQL, Material-UI and Node.JS, TypeORM on the backend with PostgreSQL database.

2. An admin page with data server connected with smart devices. This project was heavy backend based received data via UDP packets and them database, then linked these data to the admin ui. Tech stack is exactly the same as mentioned at the frst project.

Both of the projects ran with agile/scrum methodology with sprints.
