I worked closely on the admin portal and the mobile app of InviSense. A product that aims to reduce costs of moisture-related damages by implementing a sensor developed by InviSense within the walls of the structure then read the moisture levels using an external scanner that is also developed by InviSense.

My role involved the development of the mobile app using React Native. Where after successful authentication of the user, it is used to communicate with a scanning device using Bluetooth to fetch the moisture level and then send the readings to the server.

I was also involved in the development of the back end, where I worked on restructuring the database, implementing parts of the REST API, as well as enhancing and building new functionalities in the admin management UI.
