Self-Directed Learning

I have been a self-taught learner since the start of my career. Whenever a subject sparks my curiosity or a problem demands a new skill, I learn it from primary sources: documentation, books, papers, code. Over 25+ years this has covered software engineering, networking, cybersecurity, cloud, ML/AI, management and organizational design. I treat learning as a permanent practice, not a phase.
