Low Kah Yi Engineering leadership · Singapore
Reliable systems.Through change. I lead engineering teams that keep control systems and digital infrastructure running through change. Here I write about reliability and build small models of how systems fail and recover.
Nine years in 24/7 operations · Controls · Modernization · Recovery Independent experiments in power, cooling and recovery.

Design reviews split a plant by discipline; faults do not. One synthetic unit shows a redundancy in one discipline defeated through another.
