01 · About

Same question, different materials.

Mechanical engineering taught me how physical systems fail. ISO 9001 taught me how to prevent failure systematically. Production AI is the third application of the same discipline. The question never changed: how does this system fail, and how do I build it so it does not?

Mechanical Engineering → ISO 9001 Quality → AI/ML Engineering
