Engineering student.
System thinker.

My name is Bastien Gaffet. A CPGE PCSI student, I build systems at the intersection of engineering, design and curiosity. Every project is a way to better understand how things connect: code, matter or ideas.

Outside the systems I create, I observe the world through photography, music (guitar), volleyball, and astronomy.
