Engineer by training.
Observer by habit.
LI YUNFEI / [email protected] ↗
I work across engineering, data, and the stubborn reality of physical systems.
My experience moves through sustainable mining, underground blasting, applied analysis, and digital tools. I use this archive to keep technical work close to the human and material contexts that give it meaning.
Observation before certainty. Useful tools before impressive abstractions. Revision when the ground says otherwise.
