Data Sistah (Tiffany Teasley)

What it is

Tiffany Teasley taught high school math for 20 years before moving into data science and AI. Her site collects free guides, portfolio project ideas, and mentorship for career changers breaking into data and AI without a computer science degree or connections.

Why I recommend it

She is transparent about spending $21,000 on bootcamps that produced no interviews, which is exactly why I trust her advice about proof over certificates.
