About

Hey, I'm Jesse.

I've spent 20 years working in data — telecom, broadband, digital advertising. My day job is data and BI leadership: Tableau, Databricks, PySpark, the whole stack. I spoke at Tableau Conference in 2019, and I've been building analytics systems since before "data-driven" was a buzzword.

On the side, I build things. I'm an indie iOS developer with apps live on the App Store, and I design websites for local Colorado businesses. I live in Parker (south Denver metro) with my family, and I do this work because I genuinely like making useful things.
