My Work

I was responsible for the design and development of the entire Openr ecosystem. The central backend is made in Django (Python) and provides an interface for managing users, buildings, doors, access, etc. It features its own API for connected devices (intercoms, doors) and services (mobile app) and also communicates with external API's such as Particle and Twilio for unlocking doors and setting up voice calls respectively. The intercom application is written in Java as it runs on an Android tablet. It uses the Twilio SDK for making calls to Openr users. Finally, the web application for door access was written in React.
