Who writes these articles?
The Chạm AI Agency team in Ho Chi Minh City, Vietnam - practitioners who build AI agents, phygital activations and GEO-optimized websites for small and mid-sized businesses. Each article names its author with a linked profile; frameworks come from client work in 2024-2026, not from theory.
