I credit educational and science programming as a continuing influence on my approach to engineering — Veritasium, StarTalk and 3Blue1Brown have been informal sources of mathematical and physical intuition. I prefer to write clean, efficient and maintainable code, and I have a continuing interest in full-stack development, machine learning and cloud computing.
