Jason Brownlee

Hello and Welcome!

I'm a research scientist and software engineer. I write words+code to help people solve hard problems.

I trained and worked as a Software Engineer for many years (e.g. enterprise, R&D, and scientific computing), but I'm known online for my work on Computational Intelligence (e.g. Clever Algorithms), Machine Learning and Deep Learning (e.g. Machine Learning Mastery, sold in 2021) and Python Concurrency (e.g. Super Fast Python).

Five things about me:

I grew up on the Internet in the 90s, also Melbourne, Australia.
I'm a programmer that explored a Masters and PhD in computational intelligence.
Quake (1996 computer game) got me into programming and AI and has a soft spot in my heart.
I read a lot, 200-300 books/year, mostly non-fiction.
I've authored 40+ technical books and thousands of tutorials/essays.
