About

Hi, I’m Brian Langenfeld. I do things with computers — mostly marketing automation, A/B testing, data visualization, and custom software development.

Why “Knotfield”?

Some people are born Smiths or Joneses. These are the lucky ones, because anyone can spell their last name.

I was born a Langenfeld, which — despite being spelled exactly as it’s pronounced — consigned me to a lifetime of hearing Langenseld, Langenfelt, and Langenfield. Especially that last one. It’s not “field”, it’s “feld”.
