Ari Kast

Software Engineer & Musician


I'm the creator of, a search engine for local live arts, and, a musically searchable index of Bach's music.

I'm also author of Stride Piano Tricks, a popular guide on how to play early jazz piano.

Here I write about the twin arts of software engineering and musicianship, and perhaps the occasional life-hack or two.
