:Lift Box is an application designed to collect and use training data from groups or gym boxes. A gateway connects to multiple smart lockbars and gathers motion and performance data during workouts. The app retrieves this data from the gateway via WebSocket and displays it in real time in a clear and easy-to-understand way. Users can view motion data, track lifted weight, and monitor their training progress over time. Lift Box provides a practical solution for analyzing group training data, helping users and coaches better understand performance and evolution.

ABCCar controls a car’s pneumatic suspension system using a mobile device. It communicates via BLE (Bluetooth Low Energy), allowing the user to adjust the suspension in a practical and intuitive way. The project involves migrating an existing app originally developed in Java to Flutter. This makes the application more modern and allows it to run on Android and iOS while keeping the same core features. Through the app, users can send commands to change the suspension settings and receive information about the current status of the system, with great control and convenience.
