I build hardware in public, from Hong Kong. Dealwa is the main quest: your favorite branded water, living in your bottle. The lab holds the side experiments, robotics and systems. When a team manufactures in China, I help them avoid the usual traps: factories, compliance, and manufacturing deals.



Moi je bois du sang pour vivre... par contre vous, il faut boire de l'eau !
