Quoc Nguyen
// Tech Lead & Builder //
I started coding in 2010 and honestly haven't stopped since. Over these 16 years, I've built POS systems serving 60+ stores, healthcare applications, mobile solutions, and a wide range of automation tools and ERP systems—plus a few games.
Based in Ho Chi Minh City, I collaborate with teams worldwide and mentor impactful projects like RecyclerWorld (an NGO), Amazon automation suites, and enterprise help desk solutions.
