Soutenir DUONG NGUYEN (The Day)

I am a developer in the process of learning and building real products.

I’m interested in technology, systems, AI, and turning knowledge into practical value.

Here, I share what I’m learning, what I’m building, and what I struggle with along the way

from code and architecture to technical thinking, product sense, and market perspectives.

If these insights help you save time, avoid mistakes, or see things from a new angle,

buying me a coffee is a simple way to support my work and keep it going.
