Dan Gerlanc

I co-founded .txt as CTO and raised $11.9M in 2024. Over 15+ years, I’ve built technical teams from scratch as VP of Engineering at Normal Computing, 5 years leading 8+ engineers at Ampersand, and founding a boutique consulting firm.

I’ve taught thousands of students through O’Reilly Media courses on Python, Pandas, and Dask, maintaining an 8.56/10 instructor rating from 104 student reviews.

I am available for fractional CTO/VP Engineering work.
