Projects

AzSat

I co-developed a can-sized satellite module for the CanSat 24 competition.
My contributions included working with Arduinos (C++), developing a Java app, a React-based web app, and real-time telemetry between the module and the website.
Our team was awarded the Ground Station award from ESERO and the Antenna award from ANACOM.
