I'm Gwenfred Tham, a Computer Science (AI) graduate from APU in Kuala Lumpur. I build computer vision and applied AI systems for real problems, from PCB inspection on a factory line to the till at a real hardware store.
I care most about the parts that keep a system honest: rules that a model cannot overrule, data that stays correct without a network, and tests that pin the behaviour down.
