Clinical dentist since 2010
Jungsoo Baek has practiced clinical dentistry since 2010 and currently runs his own private clinic. Now in his seventeenth year of clinical practice — infection control its most exacting discipline — he has held to one operative principle, simple and uncompromising: no sterile evidence, no procedure path forms. The procedure is not blocked when sterility is missing — the path that would constitute the procedure is never permitted to begin.
Certum Systems, founded in 2026, is the translation of that principle into the architecture of autonomous AI systems. Replace sterile evidence with a valid authorization token, and the procedure path with a physical actuation path — and an entire class of safety architectures emerges, in which dangerous actions are denied existence at the earliest possible structural layer.
No evidence, no path. The path is not refused — it is never formed.
