About
I’m Pisek. I run AI at CJ Express Group, the Thai retail group behind CJ Supermarket and
CJ More — 2,500 stores across Thailand. I run the AI Centre of Excellence at head
office: a team of forward-deployed engineers embedded in the business, building computer
vision, recommendation and agentic systems where the company actually operates.
Before that I did a PhD in electrical engineering at Toronto, on quantum photonics —
entangled photon sources in semiconductor waveguides — then spent years designing
optical systems for AR glasses and surgical robotics. Physics taught me to distrust any
result I can’t measure, which is why I care more about evaluation harnesses than
leaderboards.
The governance side exists for one reason: a four-layer model — prevention, gateway,
observability, live protection — plus tool sanctioning and policy aligned to PDPA and
ISO/IEC 42001. It’s what lets 500 people use what we build directly, and 2,500
colleagues across HQ work with AI, without anyone betting the company on it.
