About Subhajai Benchadhikul

Subhajai Benchadhikul is a technology leader and solution architect based in Bangkok, Thailand, with over 20 years driving enterprise digital transformation across retail, e-commerce, insurance, airline, and fintech. He specialises in accelerating large-scale platform programmes — most recently leading the Central Online replatforming at Central Retail Corporation, migrating a monolithic Adobe Commerce stack to cloud-native architecture on GCP — and in bridging C-suite strategy with engineering delivery. He now builds production agentic AI systems and AI products. A background spanning Art History, Design, and Engineering brings a human-centric lens to architectural decision-making.
