I am a jack of all trades : computer science, operation research, board games, 3D modeling, 3D printing (of course !), bread baking, dessert maker, electronics, gamer, hiking, running everything in only one life to live ! :) I love being able to touch the model I imagine in my head, build and model in 3D CAD and then print using my 3D printer, there is something still magic and a bit more rewarding than all my heard of those virtual optimization algorithms ! ;)
