Hendzel is the one writing this.

I'm Krzysztof Hendzel. I live in Warsaw, Poland. I make marketing tools, AI workflows, F1 fan sites, and a few things that don't fit any of those categories.

I'm a solo builder by choice — I've worked in teams, I've run paid acquisition at scale, and shipping alone with AI in the loop is the most fun I've had in 15 years.

Things I care about: shipping fast over shipping perfectly, honest numbers over vanity metrics, owning the platforms I build on, and writing things I'd want to read in five years.
