Project Background

CSI PRO ACCESS is a security and access-control system developed within the CSI PRO Laboratory in Universidad de Sonora.

This project started as an experiment to attempt to build a system that allowed us to open the laboratory's door without having to use a key, since CSI PRO was steadily growing at the time and we didn't really have the resources to provide everyone with a key. Additionally, achieving this would make it more convenient to access the laboratory and would provide us with a reliable way of tracking who has entered.

App features

• Login with Google or GitHub
• Real-time access logs
• Support for multiple rooms
• Role-based permissions
• Ability to grant or remove access to specific users

How it works

CSI PRO ACCESS consists of many different scripts and apps. Firstly, a Python script that handles the user input coming from a keypad and controls the door's electric lock. The script communicates with a Node.js RESTful API which, in turn, communicates with the Firebase services to validate the user input.

I developed a Next.js webapp that displays the 20 latest access logs in real-time for us to see from inside the laboratory.

After the keypad method was stable, I coded a new Python script that leveraged Bluetooth to authenticate and access the lab. To take advantage of it, I developed the CSI PRO ACCESS mobile app with Flutter with OAuth authentication via Firebase and a more sophisticated data layer.

As the project grew, I decided to migrate the mobile experience to React Native because I wanted to explore it as a Flutter alternative, leading to providing a better user experience overall. At the same time, I developed a PWA with Vite for iOS users.
