Nguyenle・Learn

A student's digital notebook exploring new things in Control System, Simulation, Fuel Cell and AI. A space for learnings and sharing along the journey.

Not just the technical side, but also the learning process, the ups and downs, and the discoveries I make along the way.

The content is updated soon as I write new posts.

Thank you for be here!
